ECONOMIC DEVELOPMENT

Great Optimism for the Future German Pump and Compressor Manufacturers in 2018

Christoph Singrün and Ulrike Mätje

Manufacturers of liquid pumps as well as compressors, compressed air and vacuum technology benefited from a recovery in sales in 2017. In both segments, expectations for 2018 point towards an increase in sales of 3 percent.

Liquid pumps:Production picks up again in 2017

According to figures published by the Federal Statistical Office, the production of liquid pumps (excluding hydro pumps) amounted to 4.5 bil-lion euros in 2016, marking a decline of 4.7 per-cent compared to the previous year. At more than 40 percent, manufacturers of centrifugal pumps account for the largest share, while man-ufacturers of oscillating and rotating displace-ment pumps achieved 9 percent each. Produc-tion amounted to 3.4 billion euros in the first three quarters of 2017, an increase of 1.8 per-cent compared to the same period in the previ-ous year. The overall volume for 2017 is estimat-ed to be 4.6 billion euros.

The incoming orders statistics for liquid pumps which were compiled based on information pro-vided by VDMA members, reflect the economic situation of German pump manufacturers (Fig. 1). Throughout 2017, demand was up three per-cent in real terms compared to the previous year’s level, with foreign demand (+4 percent) increasing slightly more than domestic demand (+ 2 percent). At 80.4 percent, capacity utiliza-tion as an indicator of order backlog was at the lower end of the scale in January 2018. In addi-tion, sales achieved in 2017 fell one percent short of the values achieved in the previous year.

Germany remains in first place

According to the Federal Statistical Office, ex-ports of liquid pumps amounted to 5.0 billion euros in 2016, thus recording (only) a slight de-cline (–1.7 percent) compared to the previous year. In 2017, German exports picked up consid-erably, with liquid pumps (excluding hydro pumps) worth a total of 5.4 billion euros being

delivered abroad. Germany thus remains un-challenged as the world’s leading export nation. With a world trade volume of 33.1 billion euros (2016), German manufacturers make up a share of 15 percent, followed by China (14 percent) and the USA (12 percent) (Fig. 2).

With 60 percent of exports, Europe continues to be the most important sales market for liquid pumps made in Germany. Demand from China (+ 19.0 percent) and Russia (+ 22.4 percent) gained momentum compared to the previous year, while trade with Austria also increased in the two-digit range (+ 10.8 percent). In 2017, the most important purchasing countries for Ger-man manufacturers were the Czech Republic, the USA, China, France, and Italy (Fig. 3).

Compressors, Compressed Air and Vacuum Technology:Production picks up again in 2017

According to the Federal Statistical Office, pro-duction of compressors, compressed air and vacuum technology (excluding pneumatic tools) amounted to 4.7 billion euros in 2016, a slight increase compared to the previous year. Turbo compressors make up the largest share at 35 percent, followed by rotating displacement compressors at 18 percent, vacuum pumps at 16 percent, and vacuum pump and compressor components at 15 percent. Production in the first three quarters of 2017 amounted to 3.6 bil-lion euros, increasing by 2.9 percent compared to the same period of the previous year. The overall volume for 2017 is estimated at 4.8 bil-lion euros.

The incoming orders statistics which were com-piled based on information provided by VDMA members show that incoming orders in 2017 increased by three percent compared to the pre-vious year. Domestic demand was on par with foreign demand (3 percent each) (Fig. 4). In addi-tion, sales in 2017 increased by three percent compared to the previous year.

Germany remains the leading export nation

At a world trade volume of 31.7 billion euros in 2016, Germany’s world trade share amounts to 16 percent (Fig. 5), with runners-up Italy and the USA lagging behind considerably (at 9 percent each).

Europe continues to be the most important sales market for German compressors, com-pressed air and vacuum technology. 54 percent of all exported goods remain on the old conti-nent, 85 percent of which are delivered to EU countries. Trade with the USA (+7.8 percent) and China (+6.7 percent) has recovered compared to the previous year. The main buyer countries in-clude the USA at 11 percent (Fig. 6), China, Italy, France and Great Britain.

Pumps and compressors “Made in Germany” continue to be in high demand VDMA supports its member companies in con-solidating and strengthening the global market leadership of the German pump and compres-sor industry in 2018. We continuously strive to increase our presence in promising foreign mar-kets by organizing “German pavilions” as part of German export promotion campaigns. In addi-tion, VDMA coordinates joint fundamental re-search projects, which are indispensable when it comes to continuously improving products. Manufacturers of pumps and compressors, compressed air and vacuum technology also benefit from and promote new approaches in the field of Industrie 4.0. Topics such as sustain-able production processes and products and energy efficiency continue to be perennial issues in this regard.

12 ECODESIGN


European Ecodesign Legislation: VDMA Commitment for Pumps and Compressors

Friedrich Klütsch and Andreas Brand

Helping to shape ecodesign legislation and timely information on planned implementation procedures: VDMA Pumps + Systems and VDMA Compressors, Compressed Air and Vacuum Technol-ogy actively support their members in this process, showing relentless commitment in the face of adverse circumstances. So, what is the current status of Pumps and Compressors?

Situation of the pump manufacturers...The revision of pump-relevant ordinances 641/2009 „Heating circulation pumps“ (in-cluding supplement 622/2012) and 547/2012 „Water pumps“ is more than a year behind schedule. This may be a testament to the in-creasing complexity of the subject, but it also has to do with a change in staff in the Commis-sion and the results of preliminary studies that do not completely satisfy anyone. The so-called Consultation Forum, i.e. the last joint meeting of the industry and the EU Commission, origi-nally scheduled to take place in February 2017, was re-scheduled to December 2017 and then to February/March 2018. Now, we assume that, with some luck, this step may still be taken before the summer break 2018. This will also depend on the conclusion of the Motor Ordi-nance (640/2009), which, due to an extended product approach, is closely linked to the pump ordinances.

In mid-2017 it looked as if ordinance 641/2009 would be adopted with just some minor cor-rections in terms of thresholds, if any. But as a result of the newly opened discussion on inte-grated products (e.g. hot water generators), the commission may have to take a closer look at the product group and the revision of this ordi-nance. A ‘cosmetic’ adjustment, for example in the form of increasing the so-called benchmark („best technology available“) had been expect-ed and would have passed the decision-making bodies without much discussion. For formal reasons, however, we will now have a discussion in the Consultation Forum because the relevant

industry sector submitted a request to extend the exemption periods. This may additionally delay the heating circulation pumps ordinance.

Together with the revision, ordinance 547/2009 („Water Pumps“) has also been extended in terms of scope of application. The new ordi-nance will also cover multi-stage horizontal centrifugal pumps, multi-stage submersible motor pumps („borehole pumps“) and booster systems (boosters). We do not expect waste-water pumps (which the Commission originally also wanted to be included) to become part of the revised ordinance. In this regard, a consen-sus was found as a result of our discussion with the EU Commission and the study author, post-poning the regulation for these pumps to the next revision (in 5 years). Within this period, the European Pump Manufacturers’ Association, Europump, will lay the foundation for the ener-gy-related description of the various wastewa-ter pumps and their wide range of applications. The operator side will also be taken into account in this context, as their processes in the trans-port, cleaning and treatment of different water qualities are closely linked to the wide range of available pump types.

However, the crucial point currently is the imple-mentation of Europump’s endeavour to extend the product approach. In addition to the pump, the extended product now also includes the motor and possibly a controller (e.g. frequen-cy converter). Only a holistic approach, which will include these components, will generate the energy savings environmentalists and the

13ECODESIGN


Commission are talking about. For the pumps considered, a restriction to the hydraulic part (pump) would only provide about 10% of the savings that could be leveraged if the extended product was included. Values ranging from 5 to 50 TWh were mentioned in this context. Euro-pump, in cooperation with the Technical Univer-sity of Darmstadt (Prof. Pelz, Prof. Stoffel), has created an algorithm for calculating a so-called energy efficiency index (EEI). The EEI provides an application- and size-independent statement on the energy efficiency of a component (pump, motor, frequency converter). Based on the algo-rithm and the pre-determined operating param-eters, a distributor of the complete product will be able to calculate the most efficient combina-tion and to demonstrate it by own tests.

However, doubts were raised in recent discus-sions with the EU Commission about the feasi-bility and the verifiability of the EEI by market surveillance authorities. The Commission is now considering to limit the ordinance to the individ-ual components instead of covering the extend-ed device. If this approach were to succeed or be pushed through, the EU‘s climate goals would be difficult to reach, Europump’s extended prod-uct approach would have failed, and a 15-year commitment to the eco-design process would come to a disappointing end—certainly not a good example.

Europump is therefore quite tense about the upcoming Consultation Forum, especially be-cause—in the event of a further delay—the work in this field will only be continued by the next Commission (from mid-2019, after the elections).

Situation of the manufacturers of compressors, compressed air and vacuum technology...

Since the Consultation Forum was held on Octo-ber 23, 2014, the legislative process for standard air compressors (oil-injected/ piston/screw/multi-cell compressors) has been suspended. In the meantime, another study on oil-free and low-pressure air compressors was published. It was completed in mid-2017 with the publica-tion of a final study report.

Significantly lower than expected energy consumption

The main findings of the study are that oil-free and low-pressure air compressors consume sig-nificantly less energy than previously estimat-ed—only approx. 25 TWh in 2015 instead of approx. 80 TWh. In addition, the author of the study calculated only very minor savings for oil-free and low-pressure air compressors (0.35 TWh/a in 2040, with a banning of 40% of prod-ucts from the market). Higher savings (on the other hand) are calculated for the newly intro-duced scenario (“Applying heat recovery”) based on very rough assumptions; approx. 2.6 TWh/a in 2040 in addition to BAU („business as usual“, if 20% of the DL systems had heat recovery). However, only rough assumptions were made in this regard; physical and technical circum-stances were insufficiently considered. When the study text was drafted at the beginning of 2018, the manufacturers therefore expressed strong concern regarding a mandatory require-ment to install heat recovery elements in all compressors sold then.

Outlook

The industry is currently opposed to combining the standard air compressor legislation with that on oil-free and low-pressure air compres-sors. The relevant working groups produced the respective data collections at different times and using different methods, and mixing the legislative definitions for different products would be counterproductive.

The EU Commission intends to discuss the next steps in this legislative process in the context of a Consultation Forum, which will probably be held in the summer of 2018. There are indica-tions that the EU Commission will not propose a minimum efficiency regulation for oil-free and low-pressure air compressors in the forum because of its low savings potential.

14 INDUSTRIE 4.0


Administration Shell Makes Pumps a Key Element in Industrie 4.0

Jochen Müller

Pumps play a vital role in more than just the process. In tomorrow’s increasingly connected information world of Industrie 4.0, standardized pump information offers great potential to make pump operation more productive, for example by reducing maintenance costs, increasing availability and enhancing energy efficiency. In order to support ongoing developments in Industrie 4.0, pump manufacturers in the VDMA associations Pumps + Systems and Compressors, Compressed Air and Vacuum Technology are now developing a manufacturer-independent administration shell for pumps and vacuum pumps. This administration shell introduces pumps as a participant in the Industrie 4.0 environment and thus a key element of future process optimization.

Motivation

Industrie 4.0 means intelligent digital connec-tion of products and processes in order to op-timize the value chains of manufacturers and users. For pump manufacturers, Industrie 4.0 offers potential to optimize pump production processes (smart production, e.g. optimizing the quality, throughput and capacity utilization in production), while innovative smart products and services provide potential for pump users to optimize their own business processes.1

In the age of Industrie 4.0, the requirements for pump functionality are changing. While devel-opments used to center around technical prod-uct and process innovations, the focus of future innovations will be on supporting pump users in optimizing their business processes. When com-bined with services and expert knowledge, in-telligent pumps can, for instance, detect signs of wear or potential for increasing energy efficien-cy. Complex analysis methods, such as vibration analyses, can be conducted using cloud-based applications. It is important that end users map the results of such analyses to useful standards, such as the NAMUR status for the standardized representation of maintenance information. As well as potential for optimization in main-

tenance or energy management, the availabil-ity of standardized information for identifying pumps is essential for efficient documentation, order and device management.

Pump users can only be supported in the opti-mization of their business processes successful-ly and efficiently if standardized information is seamlessly integrated into their IT architecture horizontally and vertically, without the infor-mation having to be laboriously engineered by hand. This all comes down to the core task we are facing: formally describing and structuring the functions and information of pumps in the Industrie 4.0 environment. Pump manufactur-ers in the VDMA associations Pumps + Systems and Compressors, Compressed Air and Vacuum Technology are now tackling this challenge by developing a manufacturer-independent ad-ministration shell for pumps.

Administration shell and preparatory work

If a pump is to participate in the Industrie 4.0 environment, it must have a digital represen-tative, known as an administration shell. This is the link between the smart physical pump that is able to communicate and the Internet of

15INDUSTRIE 4.0


Things and services. Together with the pump, it forms the Industrie 4.0 component.

Fig. 1 shows the general structure of the admin-istration shell (see also Footnote 2 for the defi-nition). Standardized submodels that describe different functions of the of the pumps, such as configuration, diagnosis, control etc., with a structured quantity of standardized features in accordance with IEC 61360 are integral parts of the administration shell.

The “Device Profile for Liquid and Vacuum Pumps” (VDMA Specification 24223) is an excel-lent basis for specifying the submodels. It stan-dardizes fundamental functions and informa-tion on vacuum and liquid pumps in operation, across applications and irrespective of commu-nication-specific properties.3

The device profile defines the functional device architecture, the structure and the meaning of

Fig. 1: General device profile for pumps and structure of the administrative shell

the device parameters. Device functions (e.g. identification, configuration, actuation, mea-surement, monitoring, diagnosis etc.) are de-scribed in the form of general building blocks and serve to define four specific pump types: universal pump, process vacuum pump, tur-bo-molecular vacuum pump and centrifugal pump..4 The profile serves as the basis for de-veloping communication-specific enhance-ments (PNO: profile for intelligent pumps, 2008, CANopen device profile for pumps, 2010) and as the basis for products from var-ious pump manufacturers.

Transfer of the pump profile into an administration shell

The aim of the VDMA working group “Pump 4.0 – Administration shell for pumps and vac-uum pumps” is to transfer the general device profile into an administration shell and to

map the general stipulations for OPC-UA-com-pliant communication.

VDMA Specification 24223 provides an exten-sive semantic inventory for describing the oper-ation of pumps, although additional phases in the pump life cycle are not included. When the pump profile is transferred into an administra-

tion shell, the phases of the pump life cycle that need standardization (e.g. planning, ordering, delivery, commissioning, operation and remov-al) must therefore be defined. Existing feature specifications, such as eCl@ss, can be refer-enced for ordering and commercial processing.General feature specifications of IEC 61360 must also be taken into account in implement-ing the profile’s components. As a general rule, features should not be defined multiple times. Instead, existing features should be checked and merely referenced where suitable (see Foot-note 5 for the mechanisms for this). Avoiding multiple specification of features is especially important for fundamental recurring functions of Industrie 4.0 components, such as for consis-tent identification. Coordination with Plattform Industrie 4.0 committees and working groups on the creation of administration shells is need-ed here.

OPC UA is currently becoming established as a preferred communication technology in the Industrie 4.0 environment.6 VDMA’s current work on machine tools and plastic and rubber machinery focuses on standardized OPC UA in-terfaces for the digital connection of machinery with its environment.

One of the benefits of OPC UA is the availability of a meta model that makes it possible to find specific information models and creates princi-ples for the automatic execution of rules. The idea is therefore to create an OPC UA compan-ion specification based on the submodels of the pump administration shell that enables the ad-ministration shell to conduct OPC UA-compliant communication.

Made up of representatives from pump man-ufacturers, VDMA associations and TH Köln, the working group will begin activities in early March 2018. Initial results are expected by the end of the year.

18 INDUSTRIE 4.0


Industrie 4.0 and digital transformation solutions are a priority for many pump, vacu-um equipment and compressor manufacturers. The race to develop new business models has just started. Cyber security is a system security challenge at this point.

There is an increasing need for individualized products. To be ready for the impending chang-es, companies must take a fresh look at their production and logistics flows and re-structure their operations. The magic word here is Indus-try 4.0. “Cyber-physical production systems” will control and monitor new production processes. The term “cyber-physical production systems” refers to tight integration between real (phys-ical) process flows and information processing. Global information networks with always-avail-able connectivity provide the basis. The physical processes consist of embedded sys-tems which exist in a technical environment. The virtual pro-cesses are data, information and services which can be made available on the information net-work. Cyber-physical production systems have the advantage that they can be adapted quickly and efficiently as re-quirements change.

App in the cloud

In response to rapidly increasing energy costs, more and more electronic components and sensors are being installed on rotating equip-ment. However, that is not enough to make the components Industry 4.0 ready. Data genera-tion (big data) must be followed by data analy-sis and interpretation (smart data). Sensors provide data, microchips with on-board soft-ware interpret the data and actuators initiate the appropriate response. Practical implemen-tation of Industry 4.0 means that a system no longer operates exclusively under the guidance of a central process control system. Intelligence migrates to the field level. Smart field devices execute specific functionalities and option-ally may monitor and control other technical equipment.

19INDUSTRIE 4.0


The next step is the digital counterpart in the cloud. The digital twin can access other data sources or communicate over a network with other digital twins, e.g. as an active element in a cyber-physical system.Connectivity and inter-activity are essential for Industry 4.0 readiness. The compelling bene-fits for plant operators are enhanced transparency and higher system avail-ability together with increased productivity.

The big data to smart data business model

Smart Data provides an opportunity to gener-ate business models which in the past were not feasible. Manufacturers have been selling hard-ware, but what they are really selling is con-vey-ance of the medium. Customers could conceiv-ably pay for conveyance of a medium from A to B without investing in the hardware. It is up to the manufacturer to design a materi-al flow process which is as efficient as possible. This approach generates additional value-add for conventional solutions. Service is becoming an increasingly important factor in the machinery manufactur-ing indus-try. In the future, rotating equipment suppliers will offer products that have a high-er service ratio. Many pump suppliers clearly intend to expand their service and spare parts business.

Smart Data provides an opportunity to generate new business models.

Safety and security — critical infrastructure?

Despite all the euphoria about the digital trans-formation, security must not be neglected. A hacker recently gained access to the system which controls the waste water pumps in a large German city. Fortunately, the control sys-tem crashed.

Functional safety on automation systems makes it possible to protect equipment and sys-tems and prevent human health risks and environ-mental hazards. IT security provides protection against harm caused by external attack. In both functional safety and IT security, unauthorized access can interfere with systems, causing them to malfunction.

The three main IT security protection goals are confidentiality, integrity and availability. The regulations and standards can create the basis for inter-company networking.

The cyber security world and security technolo-gy are still evolving, and there is a certain lack of clarity about the extent of unauthorized access. The goal of the cyber security teams is secure, reliable automated data exchange between network-connected production sys-tems along with protection of products and systems.

Permanent Magnet Motors in Pump Systems Increase Energy Efficiency for Water Management

Thomas Schmidt, Ulrich Hentrich and Jana Schrader

Growing environmental awareness and the steadily rising energy prices have brought the topic of energy efficiency into the focus of politics, business and the general public. Almost half of the industrial electricity consumed is used to power electric motors. Many countries have therefore introduced binding energy efficiency regulations. Water management, which uses electric motors to drive pumps, is also looking for ways to save energy. One solution is the use of permanent magnet motors in pump systems.

Producing potable water in the Harz region: The use of permanent magnet motors in water management pump systems increases the energy efficiency of the plants.

21PUMPS & SYSTEMS

For decades, increasing performance, coupled with reducing manufacturing costs, was at the forefront of manufacturing drive units for pumps. However, this attitude changed fundamentally with the beginning of the energy transition movement and the constantly rising energy costs. With the demand for high efficiency, energy performance is now in the foreground. As a result, water management has been striv-ing for some time now to continuously improve the energy efficiency of its pump systems.

Many companies have already introduced a systematic energy management system in accordance with DIN EN ISO 50001. The imple-mentation of the international standard means that energy-intensive companies in the manu-facturing industry only have to pay a greatly reduced EEG levy (Renewable Energy Sources Act). This type of energy management system may also provide electricity and energy tax relief.1 One of the most effective measures for saving energy in water management is the con-version of old pump systems to energy-efficient pumps and drives.

Life cycle costs of pump systems

Often, only the efficiency of the pump was con-sidered when previously analyzing the econom-ics of pump systems. Conversely, the efficiency of the motor, which is determined by the ratio between the electrical input and mechanical output power, was largely ignored. However, the overall efficiency of the complete pump system has an impact on the energy costs and, with a share of more than 80%, is a decisive factor in economic efficiency. In comparison, the acquisi-tion costs amount to only approx. 8% and the maintenance costs of the complete system to approx. 10%. The investment and maintenance costs are therefore negligible compared to the energy consumption costs. In other words, the greatest savings in electricity costs can be achieved through the optimization of the com-plete system.²

This is why water supply companies are cur-rently working extensively to continue to reduce the life cycle costs of pump systems and to save energy in a sustainable way. The only way to achieve considerably better energy performance while simultaneously increasing the degree of

efficiency is to switch from asynchronous to synchronous pump drives. In this context, the technology of submersible motors with perma-nent magnets is increasingly becoming the focus of attention.

A new energy-efficient motor concept for submersible motor pump systems comprises permanent magnet-synchronous-submersible motors in 6”, 8” and 10” sizes covering a power range of 4 kW to 350 kW. The systems with fre-quency converters can be supplied in 50 Hz and 60 Hz versions. For the use in different media the 6” permanent magnet-synchronous-sub-mersible motors are available in the X (AISI 316) and Y (AISI 904L) versions, the 8” and 10” motors in C (AISI 304), X (AISI 316) and Y (AISI 904L) ver-sions. This means that all parts in contact with the pumped medium are made of stainless steel. By using physiologically safe materials, any contamination of the pumped medium can be ruled out, making the permanent magnet motors suitable for use in potable water. The motor connection cable is available in different quality grades, designs and lengths depending on the application. For potable water applica-tions, the cable which has KTW approval (suit-able for contact with potable water) is also avail-able in a shielded version. The aim is for a power loss of less than 1% in the cable.

Efficient technology with permanent magnets

The permanent magnet-synchronous-submers-ible motors are designed for the operation of submersible pumps, but are also suitable for the operation of other machines in subsea and marine applications.

In the case of electric motors, a torque is generated in the field of an electromagnet by the force of a current carrying con-ductor. The rotors of asynchro-nous drives require a current to generate the magnetic field. The heat created by the current and the losses due to changes in magnetization cause rotor losses, which account for almost 30% of the

total motor losses alone. The rotor of the syn-chronous motors, on the other hand, is charged by permanent magnets and rotates in the same way as with asynchronous motors in a liquid medium. Thus, current does not flow through the rotor which means rotor loss is almost com-pletely eliminated. All motors are equipped with a waterproof special winding and can be rewound. The radial plain bearings are lubri-cated by the motor fluid which consists of a bio-degradable water-glycerine mixture and ensures frost protection for temperatures as low as –25°C. If necessary, the mixture can also be replaced by a pure water filling for use in the production of potable water. A sleeve protects the permanent magnets attached to the rotor from external influences. Coolant counteracts demagnetization of the magnets by heating. The 6” and 8” motors have connection dimen-sions which are compliant with the NEMA stan-dard and the 10” motors have internationally accepted connection dimensions. The perma-nent magnet motors can be used universally, i.e. on all pumps and as replacement motors.

Axial thrust of the pumps is absorbed by an axial bearing with self-adjusting tilting pads. The pumped medium is generally sealed off by a high-quality and wear-resistant mechanical seal. In addition, a membrane is used for pres-sure compensation between the motor and the environment. Electrical cables which are facto-ry-connected to the motors are water pres-sure-tight. The motors are also earthed inside. The design of the motors is VDE-compliant and meets the EC safety requirements for machines.

As previously mentioned, unlike asynchronous motors, current does not flow through rotors equipped with high-quality permanent mag-nets. This means that they do not start auto-matically from the three-phase mains. For this reason, the motors can only be operated with a frequency converter that is suitably equipped and designed for the required output. The fre-quency control also allows the operating point of the pump system to be adapted to actual requirements and further energy savings to be made. It is advisable to use a sine wave filter or a dU/dt filter as system supplement. Due to the operating principle of the frequency converter, high voltage rise rates and voltage peaks are generated, which would damage the insulation material of the switching points, the motor sup-ply line and the motor winding. The filter helps reduce and improve them. The sine wave filter generates a largely sinusoidal output voltage from the square voltage pulses at the converter output. The additional losses and noise in the motor are thus reduced and a quiet and safe running of the motor is guaranteed.

Submersible motor pump systems benefit users who have a continuous, reliable demand for pump performance. A system with a permanent magnet-synchronous-submersible motor only pays off with increasing running time. For this purpose, payback periods are easily calculable. In the case of few operating hours, the use of systems with permanent magnet motors is not recommended. In these cases, tried and tested asynchronous motors should continue to be used.

Advantages for the water supply

Even though the conversion to a pump system with permanent magnet synchronous rotor, fre-quency converter and filter requires initial investment, it offers enormous advantages for customers with a continuous, reliable pump output requirement in the medium and long term.

The submersible motor pump systems with syn-chronous motor have some significant advan-tages over conventional submersible pumps:

23PUMPS & SYSTEMS

High energy efficiency

With permanent magnet technology and an increase in motor efficiency of up to 15%, the entire system achieves a high level of energy efficiency. Compared to asynchronous motors, synchronous motors of the same size achieve higher performance. In addition, they are char-acterized by excellent partial load behaviour over the entire power range. The overall effi-ciency of the system can thus be increased by up to 9%. At the same time, the frequency con-verter required for the opera-tion of the permanent magnet motor enables optimum con-trol of the desired conveying parameters. The speed control allows the pump to operate in the optimum energy range, which can lead to energy sav-ings of up to 30%.

Increased service life

The significant reduction in the self-heating of the motors by a maximum of 29 K increases the service life of the permanent magnet-synchro-nous-submersible motors. Lower losses in the motor reduce the internal tempera-tures and thus protect the motor winding, seals and bearings. The temperature of the pumped medium can reach as high as 50°C due to the reduced self-heating. In addition, smaller starting cur-rents of the motors increase the running time and extend the service life. In summary, costs for operation and main-tenance of the systems can be saved.

Reduction of life cycle costs

In addition, permanent mag-net-synchronous-submersible motors can be used to drive a larger range or several operat-

ing points with only one system. The higher pur-chase costs for the synchronous motor, the fre-quency converter and the sinus wave filter or dU/dt filter amount to only a few percentage points in the life cycle of the pump system. By saving energy costs, amortization can be achieved in a short time.

The significant reduction of the motor sizes between 4 kW and 350 kW from 32 to 7 enables the entire power range to be covered by only a few motor sizes. The lower rated currents mean

that smaller cross-sections of the motor connec-tion cables can be used. This also helps reduce investment costs.

Huge energy savings for water suppliers

Examples from two German waterworks show how water suppliers can save energy and costs by converting their existing pump systems to more efficient systems with permanent magnet motors.

A waterworks in Colbitz-Letzlinger Heide has been using pump systems with permanent magnet-synchronous-submersible motors since

the fall of 2015. As part of the energy manage-ment system, the operator of the waterworks prefers to procure energy-efficient products, but also continuously checks and monitors the indi-vidual pump systems with regard to their effec-tiveness and savings potential. This also applies to the well with a flow rate of 180 m³/h. A com-parison between the existing pump of the well with asynchronous motor and the new 10” pump with 6” permanent magnet-synchro-nous-submersible motor with 22 kW showed that the electrical power consumption was reduced from 26.7 kW to 23.9 kW. The overall efficiency increased from 59.2% to 66.1%. Accordingly, energy consumption was reduced by 24,528 kWh per year. In this case, the com-pany saves €3,900 per year in energy costs for the operation of a well.

The operator of the waterworks had originally set the goal that the additional expenditure of €6,100 for the new pump system with perma-nent magnet technology should be amortized after a service life of ten years. Due to the enor-mous energy savings, however, the new system was fully amortized within two years and sav-ings of approx. €33,000 were achieved as part of a ten year projection.

In a waterworks on the Rhine, eight wells are operated with submersible motor pumps for pumping water. In June 2017, the plant operator converted a well to the new permanent magnet technology. The aquifer, a body of rock that holds water in cavities, has a thickness of 20 m. However, this thickness varies depending on the season, so that the pumps have to adapt to dif-ferent delivery heads. The operators of the waterworks meet this challenge by using a mag-netically inductive flow meter and thus ensure a constant flow rate.

For the conversion of a well, pump parameters with two operating points were also required. The first operating point was set to a flow rate Q of 250 m³/h at a delivery head of 31.5 m and a pump P2 output of 26.5 kW, while the second operating point was set to a flow rate Q of 300 m³/h at the same delivery head of 31.5 m and a pump P2 output of 32.4 kW. Accordingly, a sys-tem consisting of a 10” submersible motor pump with a 6” permanent magnet-synchro-nous-submersible motor (45 kW), a frequency converter and a dU/dt filter was supplied to the

waterworks. To the satisfaction of the operator, both operating points can be reached with this system, which in turn illustrates a further advantage of the permanent magnet technol-ogy. An initial evaluation showed that the energy consumption of the well could be sig-nificantly reduced. Previously, 0.1304 kWh was required for pumping 1 m³ of water. The new system has a consumption of only 0.0918 kWh/m³, which represents an energy saving of 0.0386 kWh/m³. At a flow rate of 250 m³/h, 9.65 kWh can be saved. With 8,000 operating hours per year under continuous operation of the pump, 77,200 kWh can be saved, which equates to savings of approximately €17,000 in energy costs.

Prospects

Permanent magnet-synchronous-submersible motors are a further step towards highly effi-cient drive motors and make an important con-tribution to climate protection. The submersible motor pump systems are an alternative that not only saves energy and costs in the long term, but are also available as a complete solution. Work is currently underway to use submersible pumps with permanent magnet motors for energy recovery. In many applications, the water from elevated tanks is fed into the pipeline at high pressure and then adapted to the supply water

pressure by means of pressure reducers. This energy is to be used for the water suppliers’ own consumption.

Mobile Centrifugal Pumps Assure Flexibility and Safety in EX Zones

René Grywnow

Pumps play a key role in the chemical-pharmaceutical industry. They have a significant impact on determining whether a system is able to produce efficiently and effectively. The commercial damage resulting from a serious pump failure is therefore all the greater due to the resulting production downtime. Mobile, frequency-controlled pumps ensure that production can be resumed as rapidly as possible. Their use also assures better cost- effectiveness and enhanced environmental protection.

27PUMPS & SYSTEMS

Today, modern production operations need to be efficient and effective. Systems should be able to run profitably at high utilization levels and high efficiency ratings, to safeguard the long-term future of a production location. Over the next few years, the chemical-pharmaceuti-cal industry stands to benefit from population growth and the associated increasing levels in demand for its products. Nevertheless, locations and their respective advantages will remain the subject of continuous scrutiny.

Pumps are a significant component in any prof-itable chemical production operation. as Along with length of service life and a high level of operational availability, Life Cycle Costs are an important purchasing criterion for any produc-tion operation. These include maintenance, operating costs, downtime costs, loss of pro-duction etc. Another aspect is of particular importance for the chemical-pharmaceutical industry: plant safety for people and the envi-ronment.

Pumps are at the very heart of production. When a pump fails, the unscheduled production downtime can incur daily costs that can run into the millions. Production businesses have devised various strategies for achieving the highest possible plant efficiency ratings, even in the event of a serious malfunction. Depending on the approach, companies may keep spare parts or even entire redundancy pumps in their inventory. From a commercial business point of view, inventory is the most expensive option because it ties up capital. However, this plan reduces risk levels and assures continuity of pro-duction.

The most commonly used pumps in the indus-try, with a market share of around 68%, are known as standard chemical pumps. As pump manufacturers comply with the dimensions specified in DIN EN ISO 2858, replacing the pump should be an easy process for the opera-tor. However, in practice, replacing a pump 1:1 is not always feasible because the hydraulic per-formance capacity of a pump is manufactur-er-dependent, and significant deviations can exist within the different sizes of product.

Some operators evaluate the replacement capa-bility of a pump using the NPAI (standard pump replacement capability index). This index charac-terizes the ratio of QBEP (best point of impeller) and QISO (standard nominal displacement vol-ume). The smaller the deviation, the greater the geometric similarity of characteristics curves, and the more easily pumps can be interchanged. Developments in drive technology and in fre-quency converter technology can contribute to making pumps more flexible to use in future, which in turn will help reduce the inventory of spare parts while enabling pumps to be operated in a more energy-efficient manner, thus ensuring higher levels of production reliability. Frequen-cy-controlled pumps can be used in a flexible manner across different sizes which reduces the need to keep replacement units in inventory.

Overview of frequency converters

Frequency converters are easy to install centrally in the switch cabinet (IP20). The performance range depends on the manufacturer and extends

The requirements profile for frequency-con-trolled pumps from an operational point of view is as follows:

• External frequency converter (switch cabinet)

• Remote frequency converter • EX zone (up to 11 kW) • Non-EX zone (up to 30 kW)

• Monitoring options • Standard monitoring • Extended monitoring • Data interchange

• EMC (electromagnetic compatibility)

The list of requirements is long and varies from one sector to another.

Mobile pumps can be used in EX areas in many different ways, e.g.:• For unloading tanks• As emergency pumps to reduce the need for

standby pumps• For batch processes• In the pharmaceutical and biotechnology

industry• As mobile process pumps

• To transport alkaline solutions, acids, solvents etc.

• To transport media laden with solids, with a solid content of up to 30%

A mobile centrifugal pump should facilitate seamless operation

The customer requirement for a frequency-con-trolled mobile pump can be as follows: The operator wanted to have a pump that could quickly replace various in-situ standard chemi-cal pumps in the event of a serious system fail-ure. The goal in this specific example was to

remove the defective pump in the event of a pump malfunction and to resume production with the help of a mobile, flexible pump. Use of this pump therefore enables production opera-tions to be maintained while the failed pump is repaired in a specialist workshop.

Pump requirements:• Zone 1, temperature class T3 (200°C) • Maximum temperature of the medium

during production operations up to 140°C• Density between 820 and 930 kg/m3• Viscosity in normal operation similar to

water• Pump failure:

• Temperature between 50 and 70°C • Non-toxic medium • Viscosity 20 to 90 mm2/s

• Existing pumps and operating points, see Tab. 2

To ensure safe operation in the EX zone – Zone 1, temperature class T3 (200°C) – the customer wished to have a unit that can be operated on

location without needing to be integrated in a higher-order control system. Tab. 3 shows the configuration options of the mobile pump.

The chemical factory decided in favor of the fol-lowing version of normally-aspirated mag-net-coupled chemical process pump:• Housing material 1.4581• Containment shell Hastelloy® C4• Containment shell thermocouple• Fluid level limit switch (suction end) up to

200°C• Coriolis flow measuring up to 200°C and

viscosities of 1 to 1,000 cP• Pressure gauge (suction and pressure side) 0

to 10 bar absolute

Fig. 2 and Fig. 3 show the characteristics range that can be covered by the mobile pump. In the event of a malfunction of one of the installed chemical process pumps, this pump can cover its function fully, i.e. it can fulfill all operating points with their different densities and viscosi-ties. The mobile pump is limited by the motor used and the power intake required at the oper-ating point. A motor reserve in the EX zone (safety factor) must also be taken into account. Depending on the size of the motor, this can be up to 20%.

There is a level switch on the suction end of the pump which detects potential flow rate interruptions and then promptly shuts down the pump. This ensures that the pump cannot run dry, and that neither the pump nor the containment shell reaches a critical tempera-ture, both of which are factors which abso-lutely must be avoided in a potentially explo-sive environment.

Temperature monitoring prevents secondary damage

The mobile centrifugal pump was equipped with a metal containment shell made of Hastel-loy® C4. This makes it possible to fit a tempera-ture sensor on the atmosphere side. Eddy cur-rents are induced during the operation of a magnetic coupling with metal containment shell. These cause the containment shell next to the magnets to heat up. During normal pump operation, this heat energy is dissipated by the medium flowing through the pump. As a conse-

quence, the surface temperature of the contain-ment shell only increases slightly. Nevertheless, the containment shell has the highest surface temperature of any component on the pump.

In unauthorized operating statuses such as • when operating against a closed slide valve, • when running dry or • when a magnetic coupling desynchroniza-

tion occurs,no medium is pumped, and thus there is no cooling effect.

This causes the surface temperature of the con-tainment shell to rise rapidly. This can be mea-sured using the thermocouple. Using the appro-priate devices, an alarm can then be triggered, or the pump can be shut down. Secondary dam-age can be prevented by shutting down the pump promptly. At the same time, this prevents the surface temperature of the pump from ris-ing in an uncontrolled manner, in particular on the containment shell, which can develop into a

potential combustion source in zones where there is a risk of explosion.

Flow measurement, supported by the operator on location

In the example described here, the operator decided in favor of a Coriolis flow measuring system. The determining factors were its ability to achieve the highest possible temperatures and to contend with the full range of viscosities that occur during the production process. Flow measurement can be beneficial in three ways on the mobile unit:• It gives the operator on location the ability

to pump volume-based batches around because the operator retains visual control on site at all times and is able to operate and shut down the pump via the control panel.

• The operator on site has a display screen that indicates if the pump is running against a closed valve.

• Operation within the characteristics curve takes place in the normal manner. This visual check enables the operator on site to ensure that the pump always operates within its permitted characteristics ranges at different frequencies.

Frequency converters operate efficiently and save energy

By setting the actually required operating point, less strain is placed on the pump and energy is also conserved at the same time.

With their infinitely variable feedback control capability, frequency converters start and stop the motors very gently. The advantage com-pared to mains-operated motors is no torque or

load impact. This reduces material wear in the system, components such as valves can be used longer, and repair and maintenance costs are reduced.

A comparison of the different types of feedback control confirms the efficiency of frequency con-verters. The affinity laws demonstrate this.

Stellt man den tatsächlich benötigten Betriebspunkt optimal ein, behandelt man nicht nur die Pumpe schonender, sondern spart auch gleichzeitig Energie. Durch ihre stufenlose Regelung starten und stoppen Frequenzumrichter die Motoren sehr sanft. Der Vorteil ist, dass im Vergleich zu netzbetriebenen Motoren kein Moment- oder Laststoß erfolgt. So reduziert sich der Materialverschleiß in der Anlage, Ventile sind z. B. länger einsetzbar und die Reparatur- und Wartungskosten sinken.

Mobile pumps offer numerous advantages

Modern drive technology raises the question whether the many different sizes of standard chemical pumps are actually required, and whether it may be possible to cover several of the currently existing characteristic ranges using just a few sizes of pump, and pumps which employ frequency control in the future.

Frequency control provides the operators of ret-rofit projects and mobile process pumps in explosion-protected zones with many advan-tages.

When planning a new system, frequency control can be integrated in the planning from the beginning, and appropriate pumps can then be sourced. In existing facilities, it is often very expensive to retrofit switch cabinets, particu-larly where space is limited. It is, however, possi-ble to retrofit frequency converters to pumps with power ratings of 30 kW or 11 kW (EX zone). A range of different connections (field bus etc.) can be used to integrate these pumps into a higher-order control system, based in a control room, from which feedback control operations can be directed. In future, this could provide cost savings with regards to materials and inventory management, as well as in terms of energy con-sumption and CO2 emissions. This would enable manufacturing businesses to actively contrib-ute to protecting the environment.

According to the Federal Environment Agency, trade and industry and commerce and services account for approximately 70% of all electricity consumed in Germany. The industrial sector alone accounts for almost 45% of the electricity consumed. This results in potential cost savings for electrical drives, as they consume almost 40% of all electricity consumed in Germany, with approximately 80% of that figure being consumed by trade and industry. By using ener-gy-efficient pumps, up to 5 billion kWh of energy could be saved annually in Germany alone.

Reliable and Cost-Effective Configuration of Pumps for Corrosive Media

Rudolf Gänsl

The selection of suitable pumping technology, as well as the energy- efficient use of raw materials, is especially challenging if the manufacturing plant operator handles corrosive or toxic media. When designing a pump specifically for the production of polyaluminium chloride, special materials were used to avoid any pump corrosion by the aggressive medium. Furthermore, the double hose-diaphragm pump meets the optimum technical requirements for this challenging process and ensures low- pulsation operation, while simultaneously providing favorable procurement and operating costs.

Polyaluminium chloride (PAC) is used in water treatment and in the cosmetic industry. The PAC production process presents several challenges which must be considered when selecting the suitable pump.

35PUMPS & SYSTEMS

At the end of the process chain in many indus-trial manufacturing processes, a by-product is created in addition to the desired commodity. This by-product often has a commercial use. An Indian production unit for caustic soda serves as an example. When producing caustic soda from sodium chloride, large amounts of chloride slurry are created, an acidic and therefore partic-ularly aggressive medium. Over the course of the process, the chloride is made to react with aluminium hydroxide in order to produce poly-aluminium chloride (PAC), which is an extremely corrosive solution with a pH value of between 1 and 3. A suitable high pressure pump feeds the PAC at high temperature and a pressure of 50 to 100 bar into a spray dryer, where PAC powder in micro-fine parts is produced as an intermediate product for further use. PAC is used in water treatment as well as in the cosmetic industry for making antiperspirants (deodorants).

The PAC production process presents several challenges which must be considered when selecting the suitable pump. The criteria include:

• pressure and corrosion-resistant materials• hermetically sealed process• pressure of 50 to 100 bar• temperature up to 120 °C• low pulsation • optimum efficiency• minimum costs (capex and opex)

Titanium as material

The high pressure has to be maintained in order to achieve even granulation of the PAC powder. With pressures of up to 100 bar, metals are pri-marily considered as the material for piping and valves. Both Hastelloy C and titanium resist cor-rosion. Based on specific experiences and tests, the operator decided to have medium-wetted and pressurized parts made of titanium, whereas PTFE (polytetrafluoroethylene) was to be used for seals and to separate the wet end from the drive end.

Due to their special design, displacement pumps have proven themselves for such demanding processes at high temperatures. Screw spindle pumps and eccentric screw pumps do have low-pulsation properties, however the special requirements, such as hermetic seals and mate-

rial resistances, are difficult to align with rea-sonable overall costs. Centrifugal pumps are not applicable because of the high operating pres-sure.

Undesirable pulsations

Taking the process-related requirements into account, only a plunger or piston pump can be used. In this case, the decision was made in favor of a double hose-diaphragm pump. Spray dryers are generally very sensitive to pulsations, but a triple acting pump with offset arrange-

ment of the crank shaft/connecting rod assem-bly by 120° has proven successful in ensuring operation at low pulsation. By using an appro-priately sized pulsation dampener, the residual pulsation can be reduced to less than 1.5%. Fur-thermore, the use of a triplex pump ensures

that low pulsation is even maintained at the very low maximum flow rate of 2m³/h required for this specific spray dryer.

Reduce slurry-wetted parts

The slurry-wetted parts of the feed line and con-necting pipe, as well as the check valves and valve seats, are made of titanium. While the inner parts of traditional diaphragm piston pumps, e.g. diaphragm casing and pump cover, are in direct contact with the pumped fluid, the slurry chamber of the chosen double hose-dia-phragm pump is sealed from the environment. Therefore the pump heads did not have to be made of titanium and costs were reduced sig-nificantly.

By using a flexible double hose-diaphragm, the medium is fed through the pump in a favorable way without contact to any parts subject to pressure. The pressure within the pump casing and pump head caused by the displacement of the plungers is the same in the hydraulic fluid and the medium, which means that the only function of the diaphragm is to separate the critical medium from the hydraulic fluid. Almost identical pressure is maintained inside and outside the double diaphragm, so that the diaphragms are only subject to deformation energy and no other stress. This design helps

reducing costs for maintenance and wearing parts. Material with special properties

While the hose-diaphragm for many standard applications is typically made from NBR (nitrile rubber), this particular case of PAC application only allowed for PTFE as the diaphragm material. With this special material, which is resistant to the corrosive properties of PAC, a service life of more than two years is achieved. Valve balls and valve seats are therefore regarded as the sole real wearing parts of the chosen pump design.

Safe operation thanks to proven technology

In addition to the special features, proven serial parts offer the ideal solution regarding initial and operating costs. Additional features guaran-tee safe and low-wear operation. When exchanging wearing parts, in this case only the internal parts of the check valves, the pump remains integrated in the piping. Specially developed sound sensors allow condition moni-toring of every individual valve. Thanks to these sensors, only the actually affected valve is sub-ject to maintenance, which in turn further reduces the operating costs.

The pump is usually driven by a variable speed motor. If two or more units are being operated in parallel, electronic crankshaft coupling is applied, which further reduces pulsation in the system, resulting in a uniform volume flow. By means of crank shaft coupling, an appropriate offsetting of the crank angle is maintained over the whole duration of the operating time, which means that two triplex pumps are working at the uniformity of a six-head pump.

Thus the used double hose-diaphragm pump combines the operator’s special requirements with the proven and tested properties of a serial product.

Smart Metering Allows Conserving Resources and Protecting the Environment

Michael Birmelin

Industrie 4.0 has ceased to be a futuristic vision in industries shaped by procedures and processes. Modern metering pumps meet the requirements of the fourth industrial revolution in a tremendous number of different processes. Smart control technologies ensure a fault-free metering process at all times. The pumps respond automatically to changing conditions, can be operated intuitively and they communicate using state-of-the-art technology. Not only are they robust, adaptive and user-friendly, but they also offer comprehensive networking. Predictive maintenance and minimal use of chemicals improve the quality of products and reduce downtimes and costs.

Smart metering pumps are used, for example, in industrial cooling towers, the treatment of potable and waste water and industrial and process water treatment

39PUMPS & SYSTEMS

In the process industry and chemical plants, the fourth industrial revolution or the Internet of Things (IoT) cannot become a smart process through digitalization and networking alone. The complex procedures which dominate here cannot be interrupted and require optimum availability and great awareness of safety. After all, the majority of the chemicals being stored, transported and processed are harmful to health. The processes used also require proce-dures with maximum energy savings, maxi-mum conservation of resources and maximum environmental protection. Monitoring and con-trolling the interwoven processes produces an ever increasing amount of data and informa-tion. And this needs to be designed to be as transparent as possible.

Smart metering pumps deliver holistic solutions

Modern metering pumps are equipped with fea-tures, which accommodate Chemistry 4.0 and/or Process 4.0. They reduce consumption of the raw materials and help to minimize operating errors and downtimes. This is achieved because the pumps are not only robust, adaptive and user-friendly, but are designed to offer compre-hensive networking.• They are robust: their construction ensures a

long service life and high availability.• They are adaptive: they can automatically

adapt to constantly changing operating conditions.

• They are user-friendly: they are easy to install and commission. Clear, intuitive operation ensures simple parameterization, calibration and storage.

• They can be networked: they communicate using CANopen, PROFIBUS and PROFINET at fieldbus level and can be remote-controlled using an app.

Adaptive control technology

A new metering pump with controlled solenoid drive clearly illustrates how these features are realized. As the equivalent to a frequency con-verter for a motor-driven metering pump, the controlled solenoid of a solenoid metering pump allows the precise control of the feed rate. Solenoid control can also be used to detect all

pressure deviations in order to protect the sys-tem from overpressure. What is unique about this is that no interference-prone sensors are needed. What’s more, the pump automatically adjusts its metering behaviour to the prevailing circumstances. It increases metering pressure as back pressure rises or decreases it when the back pressure drops. The pump also adapts its metering function if the viscosity of the feed chemical changes. If the chemicals are viscous, the drive solenoid is moved with more force while less force is applied when low-viscosity chemicals are used.

Automatic bleeding

When metering liquids, especially gaseous feed chemicals, gas bubbles can have a detrimental effect on the pumping process or even bring it to a complete standstill. Active and passive bleed systems ensure that the chemicals are metered smoothly.

Modern metering pumps meet the requirements of the fourth industrial revolution.

Active systems involve electromagnetically con-trolled valves or an extended diaphragm stroke which divert the gases via a bypass. Passive sys-tems, such as coordinated discharge valves, ensure that any gases trapped or produced are continually discharged. While this approach ensures smooth operation, the operator does not want to cast out the feed chemical through the bypass in many applications.

Another solution is an almost invisible groove in the valve seat. During the suction stroke, a small amount of the chemical can flow back through this groove. Should errors arise, the ability to com-press is thus re-established in just a few strokes. This type of automatic bleeding can be imple-mented without any sensors or actuators, it avoids chemical loss and is very robust. The PVDF-based material has a stable geometry and is resis-tant to most chemicals and dirt. The movement of the valve body – out and back into the valve seat – means that dirt cannot become firmly attached and is even removed from the pump. No restric-tion to functionability can be observed even when crystallising chemicals are used, as crystallisation cannot take place in the groove.

The geometries of the groove can be clearly defined for various chemicals. Here the return flow in the suction stroke needs to be minimized in a smooth operation and full functionality needs to be ensured as viscosity increases. Return-flow channels with cross-sections of between 0.005 and 0.5 mm² have proven to be the best and can be achieved by groove depths of between approx. 0.01 and 0.2 mm.

User-friendly design

Intuitive operation and simple programming of all the required pump parameters are key for error-free operation. A large, illuminated graphic display with plain text in a variety of languages ensures this. Various manufacturers use a mini-mal number of controls for rapidly adjusting parameters – a rotary dial or click wheel and pressing a button several times are the only things required to quickly access parameters or functions at different menu levels. Specifying the capacity in liters per hour avoids laborious conversions and allows the setting to be made quickly and easily. Stroke length, frequency and metering profile are all freely parameterizable. A pressure indicator on the display provides infor-mation about the existing pressure levels. The three-level LED status display, on the front of the unit, is easy to read from a distance and from all angles and clearly indicates the current operat-ing status.

Control using Bluetooth

Smart devices, such as smartphones and tablet PCs, have also become commonplace in the industrial world. Metering pumps have also become more user-friendly thanks to remote control via an app. They can be operated with ease without the operator having to stand right

in front of them. This saves work, time and therefore operating costs, especially for pumps installed in hard-to-reach places. With a sole-noid-driven metering pump, remote control is made possible through a Bluetooth module, for example: a Bluetooth-enabled Android smart device with an appropriate app can provide

almost completely wireless control and moni-toring. What’s more, the app features additional functions: parameters and options for pump mode can not only be displayed, but also selected and configured to suit almost any setup. Calling up device or diagnosis data is just as simple. Pump-related incidents are displayed in a log file and can be sent as an email, as can a complete pump configuration.

This saves time and money especially when sev-eral pumps are used for similar tasks: standard parameters can be loaded with ease for the applications at hand. And the same is true if a pump needs replacing: the parameters of the old pump are read out and wirelessly imported onto the new one.

Intuitive operation and simple programming of all the required pump parameters are key for error-free operation.

Safety and reliability must also be ensured. When establishing a Bluetooth connection to a pump, the selected pump identifies itself visu-ally via blue LEDs. However, access to the pump parameters is only provided once a four-digit PIN has been entered.

Predictive technology

Functions enabling predictive maintenance, for example using diaphragm rupture sensors, are integrated in metering pumps. A diaphragm rupture is detected immediately and forwarded as an error message. The metering pump pro-vides the operator on site with a message or an optical signal. At the same time, an electrical signal is sent to the control room. As the dia-phragm is a multi-layered safety diaphragm, the chemicals cannot escape in an uncontrolled manner. The process underway at that time does not have to be interrupted immediately. The diaphragm can be replaced at the next con-venient time, for example, when production is interrupted due to pauses or batch changes. Unnecessary downtimes are avoided and the system availability is increased by up to 20 per-cent. This also significantly reduces mainte-nance costs.

Control circuits for complete solutions

Holistic solutions for metering jobs can be achieved by the metering pump, controller and sensors working together in an optimized man-ner. Metering pumps produce a perfect control circuit when combined with the controller and sensors. When tailored to the application, pre-cise, measurement-dependent metering opti-mizes the demand-driven addition of the chem-icals needed.

The pump’s smart control technology ensures smooth metering processes at all times. Chemi-cals are metered to the process in exactly the required quantity, which improves the efficiency and accuracy of the metering capacity.

Intuitive operation

The measuring and control system plays a major role in a perfectly functioning control circuit. Future controllers are fitted with a touch display for simple operation and an interactive start wizard. Intuitive menus, including those for cali-brating the sensors, make operation much eas-ier for the user. Integrated functions for saving energy and chemicals help to significantly cut resource consumption and energy costs, enabling savings of up to 50%.

A newly developed measuring and control sys-tem, for example, reliably monitors and controls all parameters needed for efficient water treat-ment. An interactive start-up wizard uses ques-tions about system planning to guide the opera-tor through planning the complete system. The planning results encompassing all components can be transferred to the commissioning menu using drag & drop. This allows systems to be started up quickly and easily.

The touch display provides direct control. Videos support the intuitive menus, for example by showing step-by-step calibration of the sensors involved. The device can also be remotely oper-ated via the Internet when linked via a smart-phone or any other Internet-enabled end device. Peripheral devices, such as circulating pumps, filter circuits, valves etc. can also be controlled.

Networked communication

Various fieldbus systems, such as CANbus or PROFIBUS, are used for trouble-free control of the metering pumps using a central control in production and automation technology. These systems ensure seamless communication with the pumps. The controller also communicates with analog sensors and actuators, or digital ones if connected via CANopen. Links to the con-trol level are established via PROFIBUS DP-V1, Modbus and OPC.

Equipped with appropriate modules, the pumps can communicate via the industrial Ethernet, PROFINET.

Transparency through digitalization and portals

In the future, the amount of data recorded will increase significantly. Various pieces of infor-mation, whether from sensors or pumps, must not only be recorded, but also provided and for-warded efficiently for process control. This results in data-based operating models which require a high degree of mobility and transpar-ency. The relevant data is prepared and provided accordingly as part of a complete solution. Internal data is linked with external data and used to optimize operational and operating processes.

In the future, portals which can be accessed from anywhere in the world via the Internet will play a key role. They offer users multiple bene-fits in particular through their seamless and faultless operation. End user devices are com-prehensively integrated both locally and

through a remote connection. Customers and technicians benefit from direct access to all information on the devices and systems installed on site. Calibration data, set parame-ters or error statuses produce a comprehensive picture. Operating conditions, such as length of operation, capacities or pressure situations can be called up and displayed at any time for the current setup or for the setups used on previous

days and months. An alert indicates set limit and alarm values. For example, the current lim-its for liquid levels are displayed and replenish-ment is ensured in time when critical levels are reached. This allows chemicals to be procured just in time and storage tanks to be topped-up accordingly. Costly downtimes from failing to replenish in time are avoided.

Furthermore, the user can automatically pro-duce reports at no extra cost or additional effort. Official requirements can therefore be satisfied in a convenient way and documentation pro-duced with ease. All required reports can be sent directly to the relevant authorities.

Smart metering paves the way for Industrie 4.0

Modern metering pumps satisfy the require-ments of the fourth industrial revolution in pro-cesses for a very wide range of areas. Smart con-trol technologies ensure a fault-free metering process at all times: through automatic responses to changing conditions, intuitive operation and communication options using state-of-the-art technology. Users benefit from real-time transparency of measured data and increased process safety.

In this way, processes can be continuously used to capacity and optimized. More efficient pro-cess management improves the quality of prod-ucts, extends the service life of systems and reduces operating costs.

These pumps and control circuits are used, for example, in industrial cooling towers, the treat-ment of potable and waste water and industrial and process water treatment.

New Screw Pumps Provide Efficient Solution for High-Pressure Applications

Oliver Troßmann and Ralf Richter

Supplying fuel to gas turbines places high demands on the pump technology due to the extremely low viscosities of the fuels used and the very high required pressures. The use of a specially developed triple screw pump provides a lasting and highly efficient solution for this and other similarly demanding applications. The modular design of the pump acts like a screw pump kit. The segmentation into basic and add-on elements means that we can cope with all pressure levels that are currently common on the market.

Specially developed triple screw pumps are used to supply fuel to large gas turbines.Source: Václav Mach / Fotolia.com



Kerosene and diesel are the primarily used to supply large gas turbines. They have extremely low viscosities that hardly climb above the 3 cSt mark. In addition, the required pressures in these applications are very high, typically between 130 and 180 bar. This is joined by a volume flow rate, which can be more than 3,000 l/min in the most powerful large tur-bines.

High-pressure application for fluids with a low viscosity and high differential pressure there-fore place some very special demands on the design and development of a triple screw pump. The following fields of action have to be taken into particular consideration: • resulting hydraulic transverse forces• axial thrust compensation• hydraulic efficiency

Hydrostatic transverse forces

In triple screw pumps, three screw spindles that intermesh and seal each other off rotate in a close-fitting housing. The resulting sealing lines create feed chambers of different pressures. The difference in pressure between the feed chambers and their spatial offset due to the screw profile creates hydrostatic transverse forces. Fig. 1 shows the hydrostatic build-up of pressure along the screw set. The pressure increases from the inlet of the screw set to the outlet. These hydrostatic loads only affect the idler spindles of the screw pump and press these against the walls of the housing. The

drive spindle remains almost load-free because the opposite surface ratios cancel each other out.

The resulting hydraulic load can be calculated from the sum total of the individual chamber forces: The radial force on the idler spindle results from the sum total of the individual components and vector addition to the overall force:

Resulting hydrostatic transverse force

(Source, see footnote 1)

The hydrodynamic sleeve bearing forces result-ing from the sleeve bearing system between the outer diameter of the idler spindle and the housing compensate the hydrostatic transverse forces. The operating states can be designed and predicted easily with the help of general calculations of radial sleeve bearings, such as the Sommerfeld number and Reynolds equa-tion.

Axial thrust compensation

Another critical aspect when dimensioning sin-gle-volute, high-pressure pumps is the compen-sation of the axial thrust caused by the high dif-ferential pressure. A hydrodynamic compensa-tion of the axial forces analogous to the radial bearing is impossible due to the forces and the given geometric circumstances. In order to keep the system in equilibrium, the axial forces caused by the geometry of the screw profile have to be hydrostatically compensated. The sealing lines and the surface areas under a dif-ferential pressure must therefore be described exactly. Fig. 2 shows the surfaces with the same pressure in the same color.

Hydraulic efficiency

The volumetric efficiency has to be taken into account if competitive products are to be brought onto the market. This is a further important point when designing pumps with a very high pressure and a low-viscosity medium. To ensure the devel-opment of new products and fields of application remains within a reasonable economic and tem-poral framework, an exact, physically-based model of the leak flows in a screw pump should be made. Each individual gap can be modeled in terms of flow mechanics (see Fig. 3) and its influence on the overall system can be pre-dicted. This means that the optimum gap heights for special applications can be deter-mined. As a result of these measures, the volu-metric efficiency can be increased by 10 to 15%.

Development of a modular screw pump

During the development phase of the modular screw pump, the aforementioned fields of action are considered with the exact context of the application. The sleeve bearing system between the idler spindle and housing has to be dimensioned in such a way that the result-ing hydrostatic forces can be compensated with the hydrodynamic forces. As the geometry of the idler spindle also depends on the volu-metric pumping task being fulfilled, the degrees of freedom when designing the sleeve bearing are very limited. On account of the lead

and profile geometry, the diameter and effec-tive bearing width can only be varied within a very limited range.

One further aspect of hydrodynamics is viscos-ity. The bearing in the triple screw pump is lubri-cated by the pumping medium. The viscosity parameter is given and cannot be changed due to the specified application. The options for increasing the load-bearing capacity of the sleeve bearing are thus restricted to the follow-ing aspects:

• Speed• Surface quality• Reduction of the load on the bearing

Speed

The sleeve bearing theory states that increasing the speed is one parameter to increase the load-bearing capacity of a bearing. However, this is subject to technical and physical limits. The pumps are usually operated by a motor without a frequency converter, in other words at a constant speed. Two-pole motors are normally used to drive the pumps at a speed of 3,000 or 3,600 rpm. Higher speeds are also possible in principle. However, tests have shown that dou-ble the angular speed does not – as presumed by the Sommerfeld number – mean double the load-bearing capacity. The energy introduced by the higher peripheral speeds makes the sleeve bearing system much more sensitive to mixed friction states that may temporarily occur on account of the start-up and shut-down states or in the pump’s running-in phase. In addition, the sleeve bearing heats up due to the increased vis-cous friction. This temperature increase further reduces the viscosity of the fluid.

Seite1von1





(Source, see footnote³)

Surface quality A further aspect for the sleeve bearing is the choice of material pairs and/or the determina-tion of the surface qualities to be produced. With high surface qualities, the permissible residual gap in the sleeve bearing can be reduced and the load-bearing capacity therefore increased. A surface with low peak-to-peak

heights and only slight deviations in the straightness is state-of-the-art in today’s stan-dard sleeve bearings and is easy to produce. However, standard sleeve bearings have a length-diameter ratio of between 0.5 and 1.25. In the case of the screw pump, length-diameter ratios of 15 to 20 have to be expected due to the axial extension. This parameter greatly limits the optimization potential, especially with regard to the straightness. The demands made on the manufacturing technology are high, and in the case of a high-pressure pump with hydro-dynamic lubricant films, are only possible with a great deal of effort and with special tools.

Reduction of the load on the bearing

Reducing the load on the bearing, along with the speed, is a parameter that influences the height of the lubricant film and thus the func-tionality of a sleeve bearing. The load on the spindle results from the differential pressure that the pump has to exert. This parameter is given by the application and cannot be changed. Sealed chambers are formed in the screw pump that generate a linear build-up of pressure. As a result of this linearity, the differential pressure between the individual chambers is constant and proportional to the overall number of cham-bers. In turn, the chamber differential pressures define the load on the sleeve bearing system of a web. This thus leaves the possibility of reduc-ing the load on the bearing. The more chambers can be formed, the smaller the load will be. The consequence of this is that the length of the intermeshing screw packages increases.

Manufacturing quality vs. effective length

Two of the aspects described above are abso-lutely contradictory regarding the new pump to be developed. In order to achieve the necessary manufacturing quality, the length to be machined must be kept short. This is opposed by the demand for longer effective lengths in order to increase the number of chambers. A new pump was developed on the basis of this paradox that unites both contradictions (Fig. 4). Great attention was paid to the pump’s seg-mentation during its design. The segments allow optimum manufacturing parameters for each individual part. The effective length can be

increased at any time without any major effort by simply stringing the segments together. The add-on segments consist of two idler spindles and a housing part of the same length. The number of segments is defined by the later application and the hydrodynamic lubricant film required. In the application described above, this is a 10xD pump. This means that the screw package length corresponds to ten times the diameter of the drive spindle. With this design, one basic element, four add-on ele-ments, one end element as well as a bearing/seal cover are joined together.

Segmented screw pump kit

The modular design of the high-pressure pump increases the potential of a triple screw pump kit: the basic and add-on parts can be seg-mented to cover all common pressure stages currently on the market with this kit. This also makes it easier to extend the pressure stages than by extending the current common design.

Current low-pressure applications can be catered for with the basic set-up consisting of basic element, end element and cover. Medi-um-pressure requirements are covered by inserting an add-on element. Further add-on elements are inserted for each pressure stage to further increase the pressure. The only compo-nent that changes in this concept is the drive

spindle. This cannot be of a segmented design on account of the pressure ratios and the func-tion of transferring the torque to all idler spin-dles. This modularization concept allows indi-vidual reactions to the demands that are made.

The shorter overall length of the individual seg-ments allows the application of modern mate-rial layers using new coating methods for the first time. These sleeve bearing coatings improve the lubrication gap limit and thus the pump’s operational range.Various measures were taken to further improve the efficiency of the pumps, which is already very high for triple screw pumps. For example, the tolerances inside the pump were reduced at certain points. The theoretical work mentioned above acts as a foundation for this.

Advantages of the screw pump for high-pressure applications at a glance

• Low-pulsation pumping behavior: pulsation < 1% of the feed pressure

• Almost wear-free: spindles run hydrodynamically without any metallic contact

• Reduction of wearing parts: only the shaft seal and deep groove ball bearing require regular maintenance

• Simplified service: The pump is designed as a plug-in unit and can be easily removed for inspections

• Maximum flexibility through welded housing: individual customer wishes can be met

• High operational reliability

• Flexible choice of materials: from low-temperature materials through to a stainless steel design for corrosive media

• Option: cartridge seal pursuant to API 682 or hermetically tight magnetic coupling (conforms with TA Luft)

Through the development of a new, viscosity-in-dependent, axial thrust compensation system, it was also possible to achieve a much higher volumetric efficiency. The new thrust compen-sation system is 100% hydrostatic, thus making it wear-free. The improvement achieved in volu-metric efficiency is around 20%, corresponding to approx. 10% relative to the overall efficiency.

Advantages for users

The mode of operation of the screw pump makes it predestined for high-pressure applica-tions. This is mainly due to the pump character-istics of this type of pump, which have an excep-tionally low-pulsation pumping behavior. Unlike

other positive displacement pumps, the differ-ential pressure in screw pumps is distributed over the feed chambers produced by the screw profiles. The number of chambers depends on the length of the screw profile and screw pitch, and in the case of fuel supply pumps, is typically at least ten chambers. This means that the last feed chamber before the opening in the pres-sure chamber already has 90% of the system’s counter pressure. Together with the smooth opening of the chamber in the pressure cham-ber, this leads to a pulsation level that is far below 1% of the feed pressure.

One further advantage is that the high-pressure pump described here largely works without any wear in the permissible operating range. On the one hand, this is achieved by the fact that a lubricant film radially separates the spindles on sleeve bearings from the housing wall so they run purely hydrodynamically without any metallic contact. On the other hand, the opti-mized axial thrust compensation system for the spindles ensures that mixed friction states are reliably avoided in all of the pump’s operating states. This applies in particular for the start-up and shut-down processes, during which visible wear can often be detected on the front faces of the spindles in normal systems.

The shaft seal and the deep groove ball bearings used to fix the drive spindle are therefore the only relevant wearing parts that require regular maintenance. The service requirements were

also taken into account in the development: the bearing and seal can be replaced with the least possible effort as only the separate bearing/seal cover must be disassembled.

The pump itself is installed in a separate welded housing as a plug-in unit. One advantage of this is that it can be inspected without having to dis-connect the pump housing from the system. And the design with a welded housing offers maximum flexibility to satisfy as many custom-ers’ wishes as possible, for example a different flange arrangement, a specially adapted foot-print or the provision of special measuring con-nections. In addition, the active forces that can occur on the flange, for example through ten-sion in the flange connections during installa-tion of the pump in the system, are not trans-ferred to the rotor teeth. This rules out any pos-sible risk to the pump’s operational reliability.

The flexibility of the materials used is matched by the versatility of the pump’s possible connec-tion geometry. For example, the pump can be made with low-temperature materials for extreme installation sites. It is also available in a complete stainless steel version for media with corrosive or aggressive constituents.

As for the shaft seal, many years of experience have shown that the pumps can be fitted with not only the standard, single-action mechanical seals but also with cartridge seals with a supply system pursuant to API 682, or hermetically tight magnetic couplings if necessary. Apart from the leak-free requirement pursuant to TA Luft (Technical Instructions on Air Quality Con-trol), the life cycle costs can be greatly reduced if

a maintenance-free magnetic coupling is used. This, in connection with the great efficiency of the pumps, results in an extremely low total cost of ownership.

Technical Ceramics Expand the Applications of Sealless Pumps

Frank Holz

The applications of efficient, hermetically-sealed centrifugal and screw pumps have expanded substantially. Magnetic drive pumps with ceramic containment shells are now used to convey fluids with a viscosity of 0.1 to 10,000 cP at differential pressures of up to 40 bar and temperatures between –200 and +400°C. This expansion was driven by the further development of ceramic containment shells. Further advantages of ceramic containment shells include limited dry-run capability of magnetic drive centrifugal pumps, increased output density of magnetic drives, and the ability to convey low-boiling liquids near vapor pressure.

Sealless pumps with technical ceramics are used in the chemical and petrochemical industries, for example.Source: industrieblick / Fotolia.com

53PUMPS & SYSTEMS

Screw pumps

Hermetically-sealed screw pumps are used in the chemical and petrochemical industries to convey liquids with viscosities ranging from 0.1 to 10,000 cP. These screw pumps can be designed as either single or dual-flow pumps. Fig. 1 shows a single-flow design.

Screw pumps generally consist of intermeshing screws that form axially-separated conveying chambers together with the surrounding hous-ing. The surrounding housing can be designed as a withdrawable unit or as part of the pump housing. Radial and axial sleeve bearings installed in the pump housing support the screws (Fig. 1). The drive (e.g. an electric motor) transmits the required conveying capacity to the pump shaft, from where it is transmitted to the drive screw via the magnetic coupling without direct contact. The rotating screws create a chamber in the suc-tion area of the screw pump that gradually fills with the conveyed fluid. As the screws continue to rotate, this fluid-filled chamber is transported axially in the direction of the discharge side, conveying the fluid to the pump’s discharge side. Fig. 2 shows two screws installed in a with-drawable housing design.

The complete pump design, consisting of pump housing with adaptable flanges and the with-drawable unit, is illustrated in Fig. 3. Fig. 4 shows the design, consisting of suction and discharge housing with integrated flanges and with-drawable unit including magnetic drive.

With both housing types A and B, the pump housing and the suction and discharge housing can remain installed in the piping during main-tenance work, while the withdrawable unit with the magnetic drive is removed and/or replaced. Fig. 5 shows removal of the withdrawable unit for housing type B.

Screw pumps with magnetic drives offer various design-related advantages compared to mechanically sealed pumps, the most import-ant being hermetic sealing. The design of her-metically-sealed pumps does without dynamic seals, instead only using static seals and thus fully ruling out seal wear and a resulting increase in leakage.

The axial forces created in screw pumps are compensated by hydraulic balancing. In screw pumps with mechanical seals, however, the axial forces cannot be fully compensated over the entire operating range, making it necessary to reinforce the axial bearing in some operating conditions.

The magnetic drive screw pumps described here ensure full compensation of axial forces over the entire operating range of the pump, regard-less of changes in suction pressure or other pump parameters.

Magnetic coupling

Magnetic couplings generally consist of three main components: • External rotating magnetic ring

(magnetic driver)• Internal rotating magnetic ring

(magnetic carrier)• Containment shell

The drive (e.g. an electric motor) transmits the torque to the pump shaft, from where it is trans-mitted to the drive screw via the magnetic cou-pling. Without direct contact, the magnetic driver attached to the pump shaft transmits the

torque via the containment shell to the mag-netic carrier mounted on the drive screw. The containment shells can be made of metallic or non-metallic materials. When metallic contain-ment shells are used, eddy currents are created in the containment shell due to the rotating magnetic field between the magnetic driver and the magnetic carrier. These eddy currents lead to a temperature increase in the metallic con-tainment shell. To limit this temperature increase, a defined cooling flow must be circu-lated through the magnetic drive, utilizing the pressure difference created in the pump.

As a result, a critical operating point of magnetic drives with metallic containment shells is at very low pressure differences in the pump. Under certain circumstances, the pressure dif-ference may not be sufficient to ensure the required cooling flow, thus causing an unac-ceptable temperature increase in the contain-ment shell and the fluid.

Benefits of non-metallic containment shells

Magnetic couplings with non-metallic contain-ment shells are not affected by such electro-magnetic eddy current losses. Furthermore, the temperature of the containment shell and the fluid does not increase during operation. This makes it possible to substantially reduce the internal circulation (cooling flow), thus increas-ing the pump’s overall efficiency.

Ceramic containment shells

Compared to CFRP containment shells, ceramic containment shells have a considerably larger temperature and pressure range, which is one of the reasons why the development of ceramic containment shells has been driven forward in recent years. Today’s magnetic couplings with ceramic containment shells are the result of these efforts. They are available as standard equipment for pumps with the following oper-ating characteristics:• Temperature ranges between –200 and

+400°C• Pressure ratings of PN40• Transmission capacities of up to 1 MW

Special versions with higher pressure ratings are also available. The standard version comes with two different gap widths (between the external diameter of the magnetic driver and the inter-nal diameter of the containment shell). In order to reduce friction in the gap between the driver and containment shell, the larger gap width is the preferred option for conveying highly-vis-cous media. The reduced friction also leads to an increase in efficiency.

“P” drive

In addition to the required pump output, the electromagnetic losses occurring in metallic containment shells need to be compensated, resulting in reduced overall pump efficiency.

At identical speeds and when a metallic contain-ment shell is used, the transmission perfor-mance and the magnitude of electromagnetic losses of magnetic coupling depend on the strength of the magnetic field. When metallic containment shells are used, an increase in transmission performance therefore always automatically results in an increase in electro-magnetic eddy current losses.

Increasing the output density of magnetic drives is therefore only sensible when using ceramic containment shells. In this case, the transmis-sion performance can be increased with causing any electromagnetic losses. Power magnets (P magnets) make it possible to increase the trans-mission performance by 30%. Magnetic cou-plings with power magnets can now be used to drive pumps for which magnetic coupling was not available until now.

Dry-run capability

Pumps with ceramic containment shells are suit-able for use in a wider range of applications. They are capable of dry running for a limited time (in this case, “dry running” refers to a loss of suction side flow) without being damaged, which is par-ticularly useful when using pumps in batch mode or when emptying tank containers.

The design of the screw pumps ensures that all sleeve bearings are constantly lubricated with fluid, even when the pump is running dry. This is also true for centrifugal pumps of this type. The use of a ceramic containment shell also prevents a temperature increase in the magnetic cou-pling due to eddy current losses, thus consider-ably enhancing the pump’s dry run capability.

Modular pumps

To ensure that they can be used in all types of hermetically-sealed pumps, the magnetic cou-plings feature a modular design. The housing lid is used as the interface between the pump and the magnetic coupling.

The metallic or ceramic containment shells are mounted on the housing cover on the pump’s drive side. How the housing cover on the pump side is designed depends on whether the pump is a centrifugal or screw pump. Fig. 6 shows the modular system of the magnetic coupling. The use of this modular system offers consider-able benefits for users of hermetically-sealed pumps:• All parts of the magnetic coupling are

identical for both centrifugal and screw pumps

• Only one stock of replacement parts required

• Servicing and maintenance can be carried out as usual.

High-Pressure Compressors Facilitate Complex Processes in the Chemical and Petrochemical Industries

Hartwig Alber

The chemical and petrochemical industries use multi-stage high- pressure booster compressors that are perfectly tailored to the complex processes and procedures of these industries. They are particularly suitable for use in recycling and support processes, such as the recovery and reintroduction of hydrogen (H2), nitrogen (N2) or forming gas. In addition, these compressors meet the requirements for operation in explosive zones. Early warning systems and continuous monitoring of the built-in compressor system enable condition-based maintenance and prevent costly downtime.

Multi-stage high-pressure booster compressors are used in the processing of process gases in the chemical and petrochemical industries.

Source: industrieblick / Fotolia.com

Oil-free reciprocating compressors are used in the processing of process gases such as hydro-gen (H2), carbon dioxide (CO2) and ethylene (C2H4) in the chemical and petrochemical indus-tries. With an output of up to 270 kW, they can be single-stage, two-stage or three-stage and are suitable for pressure ranges of up to 250 bar. Their optimized design and the space-saving arrangement of all their components mean that they need 35–40 percent less space than other compressors. Thanks to the control via a fre-quency converter, these compressors react flexi-bly to process-related fluctuations in volumetric flow. In addition, the directly-coupled motor increases energy efficiency by 2-4 percent com-pared to belt driven machines. Less mainte-nance is also required, since there is no need to test the belt tension or replace the belt. The compressors are particularly suitable for use in recycling and support processes such as the recovery and reintroduction of hydrogen (H2), nitrogen (N2) or forming gas.

Metal diaphragm compressors with a drive power of up to 160 kW and a leakage rate of less than 10-5 mbar l/s cover high-pressure applica-tions up to 1000 bar with comparatively low vol-ume flows. These machines feature a triple sandwich metal diaphragm with integral dia-phragm monitoring, ensuring the gas and hydraulic areas are fully separated. This design creates a leak-free system. Such compressors are used, for example, to fill gas cylinders, as cycle gas compressors, and to compress rare and therefore more expensive gases. They are also suitable for dealing with highly toxic carbon monoxide or highly aggressive pure H2S, for example. Moreover, they facilitate the difficult processing of silane gases, which react and ignite immediately upon contact with ambient air.

ATEX: Safety is mandatory

Especially in the chemical and petrochemical industries, the safety of operating and mainte-nance personnel and equipment is paramount when working with toxic and highly-flamma-ble gases. ATEX certification (Atmosphères Explosibles) was introduced in the EU in 1994 in order to prevent risks. The latest version of the directive has been in force since April 2016 and stipulates minimum requirements for the

use of equipment and protective systems in potentially explosive zones. The risk potential according to ATEX is derived from the probabil-ity of the simultaneous occurrence of fuels (e.g. flammable gases) and oxygen over a certain period of time.

Compressor systems must also be adapted spe-cifically for use in the Ex-zone and the manufac-turer must verify their conformity with the ATEX Directive.

Example: Chemical plant in Taiwan

A leading Taiwanese manufacturer of petro-chemical precursors produces ethylene oxide, ethylene glycol and their derivatives. In doing so, the company pays special attention to an eco-nomical and environmentally friendly manufac-turing process. The compressors it previously used to produce ethylene glycol could no longer guarantee high availability and reliability. In 2016, these compressors were replaced by a two-stage dry-running compressor, which is used to compress a gas mixture (C2H4, CH4, CO2, N2, O2, Ar, C2H6 and other gases).

The oil-free and water-cooled dry-running com-pressor for volatile organic compounds enables gas recycling in the production processes with almost no loss at all. With the machine specially adapted to the demanding process requirements of the project in Asia, the compressor meets all local requirements for installation in Ex-zones. The compressor system PLC is the interface to the remote control station. Sensors, controls and couplers are used to integrate the entire unit into the control room. In addition, all important oper-ating parameters can be read on site.

Secondary cooling circuit prevents damage

Since the Taiwanese factory uses a water-satu-rated gas mixture with carbon dioxide, all the components needed to be designed in stainless steel to prevent corrosion. Likewise, automatic condensate discharges had to be provided as gas saturated with water vapor increases the risk of water hammer, which could lead to compressor failure and production downtime. An efficient cooling concept adapted to the process was therefore particularly important. To ensure this, the compressor has a closed secondary cooling circuit.

Cold cooling water may cause condensation on the suction valves as the compressor cools, which could damage the system. This is counter-acted by an integrated cooling system, which continually keeps the entire compressor at the required temperature using a high volume flow and a small temperature difference. A heat exchanger dissipates the absorbed heat to the open cooling system on site. Controlling the flow of the cooling water in the heat exchanger controls the secondary cooling circuit.

As the factory in Kaohsiung is close to the sea, seawater is used for cooling. This meant that the cooling system had to be designed so that sedimentation-prone solids are filtered out at the entrance to the compressor system and all the parts that come into contact with the cool-ing water are resistant to seawater. A special fil-ter system prevents the plate heat exchangers from being contaminated by particles.

Early warning system enables condition-based maintenance

Since piston and packing rings are typical wear-ing parts in reciprocating compressors, special attention must be paid to the wear of these components to prevent unscheduled machine stops. Large moving masses on the liners lead to increased stress – especially with horizontal reciprocating compressors that have a drive power of more than 500 kW. Monitoring wear therefore makes sense. Rod-drop sensors, for example, can be used to monitor horizontal sys-tems. A spacing sensor measures when the pis-ton rod gets closer to the sensor. The sensor checks the vertical drop of the piston in the cyl-inder by assessing the behavior of the piston rod and detecting the displacement of the rod in the gland. Thus, the rod-drop sensor is an early warning system that ensures system availability.

A rod-drop sensor is an electrical sensor that expresses the distance to be tested as electrical resistance (+/- 10 V). The sensor carries a certain voltage, which changes as soon as the distance between the sensor and the piston rod becomes smaller. The compressor control detects the sig-nal, triggering an alarm in the control room, whereby this early warning system guarantees proactive maintenance. For this reason, the

manufacturer must define the minimum dis-tance from which an error message is triggered in the program control. Since the Taiwanese manufacturer had used this technology suc-cessfully in the past, this sensor was also inte-grated into the new compressor system.

The sensor tells the user at the right time when the piston or packing ring is worn, so the required wearing parts can be ordered in good time. When assembled, the three sensors must be easily accessible for maintenance, positioned accurately, and as close as possible to one

another – one sensor on each of the first and second-stage piston rods and one sensor on the crankshaft. This also made it possible to equip the V-compressor with the rod-drop sensor sys-tem commonly used in horizontal systems.

Remote maintenance enables fast commissioning

interconnected machines. For this reason, it is essential that every new system fits perfectly with the existing system peripherals. Since the compressor manufacturer is the best person to interpret his system’s messages, it is always recommended that the commissioning be per-formed by the manufacturer himself in such projects. System-related assistance is often also possible in conjunction with remote main-tenance, whereby data interfaces with Modbus RTU (RS 485), Profibus and Profinet/Ethernet – preferably Profinet with PN/PN coupler – are used. In order to give the compressor manufac-turer access to the control system on site, the user must first make the physical connection and grant approval. As soon as these require-ments have been met, the manufacturer can communicate with the control and, if neces-sary, adapt the software easily and quickly and update the control.

Under certain circumstances, this system can also show whether machine parts need to be serviced or replaced. Through intelligent evalua-tion of runtimes, servicing and the required materials can be planned at an early stage. Active and prompt servicing thus guarantees maximum system availability.

When the high-pressure compressor was com-missioned in Taiwan, for example, adjustments made necessary by changed process parameters could be made via efficient remote mainte-nance. The compressor was commissioned on schedule in March 2016.

Compressed Air Storage Power Plants Store Power from Sun and Wind

Rasmus Rubycz

The amount of electricity generated from renewable energies is steadily increasing. However, wind and sunshine are not always constantly available. In order to guarantee a continuous supply and bridge any dips in supply, surplus electricity needs to be stored. Compressed air storage power plants are still largely unknown, but are already a tried-and-tested option for storing green electricity cost-effectively in the long term.

Compressed air storage power plants will be able to store green electricity cost-effectively in future.Source: Atlas Copco



Almost all areas of society and industry agree that the energy transition is one of the greatest challenges of our time. According to the Federal Office of the Environment, a respectable 31.7% of the electricity consumed in Germany in 2016 was generated from renewable sources. Wind and solar power make up around two thirds of this (61.4%) – a figure that is set to increase.

The most important renewable energy sources – wind and solar power – are clean, cheap and proven, but they have a serious disadvantage: They are never 100% predictable and are there-fore not base-load compatible. If a reliable sup-ply is to be guaranteed in the face of the ever-in-creasing proportion of green electricity gener-ated by wind and the sun, efficient and cost-effective electricity storage systems will be essential in both the mid-term and long-term.

High pressure for the energy transition

There are many options for storing surplus green electricity so that it can be used at times when there is little wind or sunshine. Among the most important systems are battery storage systems, pumped storage power plants, power-to-gas, redox flow batteries and the hydrogen infrastructure that has been propagated for decades.

One solution that is much less well-known is compressed air storage power plant technology, known as compressed air energy storage or CAES. When surplus electricity is available, air is highly pressurized by a compressor. Depending on the type of system, the pressure can be between 10 and 200 bar. The compressed air generated is temporarily stored in suitable tanks. To release the stored energy, the air is then decompressed via a turbo-generator (tur-bine and generator). The electricity generated is then fed back into the grid.

First CAES power plants support conventional electricity generation

Astoundingly, CAES technology came onto the German electricity storage market as long ago as 1978 – more than a decade before the first lithium-ion batteries were ready for the market.

Together with pumped storage power plants – another archaic solution – the Huntorf CAES power plant in Lower Saxony formed the basis of German electricity storage for years.

Green electricity did not have to be stored back then – it didn’t even exist. Instead, these stor-age power plants offered a fast-reacting reserve for the high-consumption peak load periods to support the large fossil fuel and nuclear power plants, which were extremely lethargic at the time.

There is a certain irony in the fact that, having been introduced to support fossil fuels and atomic power, this technology could now gain a key position in the reconstruction of the energy infrastructure following the extensive abandon-ment of conventional electricity generation.

Enthalpy is everything

The heating of the air is usually an undesirable side-effect compression. This is also the case at the Huntorf power plant, where the heat gener-ated during air compression (up to 72 bar) is emitted into the environment by coolers before the air is stored in a salt cavern.

The polar opposite is true during expansion. Here, the turbine draws energy from the air stream, resulting in a drop in both pressure and temperature. However, compressed air alone is not an energy storage device, but a carrier that can be charged with heat.

It all depends, to a lesser extent than for pres-sure, on the available enthalpy, i.e. the energy that can be extracted from a kilogram of air. To attain higher turbine output power, the air tem-perature should be as high as possible. This is also referred to as the enthalpy difference Δh. In contrast, the pressure merely defines the den-sity of the air, i.e. the mass flow m. This relation-ship is clearly shown by this simple equation, where P is the power:

P = m * Δh

In the case of the aforementioned power plant, natural gas is also burned in order to replace the enthalpy lost when the compressed air cools.

Adiabatic compressed air energy storage possible

In a diabatic compressed air energy storage power plant, the thermal energy created by the compression of the air is emitted into the envi-ronment. The electricity produced is a mixture of around 1/3 stored electricity and 2/3 natural gas electricity.

This process can, however, also be carried out entirely without the use of additional fuels. If the natural gas were to be replaced by the stored heat from compression, then the power plant would be an adiabatic compressed air energy storage power plant, or A-CAES. This represents a challenge in practice, however, because a medium is required in order to store heat. In addition, the temperature must be as high as possible to achieve maximum efficiency.

Numerous studies on this topic have been con-ducted, including the technically fascinating ADELE project, which has since been cancelled. Storage efficiencies of 70%, achieved at tem-peratures of approx. 600°C and pressures of 160 bar, suggest that the planners intended to expand the limits of the technically possible to the maximum.

Whereas this was new territory in many respects, an A-CAES power plant can also be operated at significantly lower temperatures. The obvious question is, what storage efficien-cies can be achieved with the machines that are already available from turbo machine man-ufacturers today? Storage of heat or com-pressed air should be conducted exclusively using the possibilities available today in con-junction with solid-state storage devices, fluids or molten salt baths, as well as salt caverns. Naturally the aim is to determine the advan-tages, disadvantages, and cost-effectiveness of such a system.

The study: A-CAES energy storage system for citizens’ wind farm In order to establish a direct relationship to reality, the key data for an A-CAES system were outlined in co-operation with a citizens’ wind farm in Schleswig-Holstein. On account

of bottlenecks in the high-voltage grid, the operators of this wind farm are frequently forced to shut down the wind turbines. Where derating was necessary due to a grid bottle-neck, the average duration of this was around 10 hours.

A compressor performance of approx. 12 MW and a gross storage capacity of around 120 MWh are required in order to absorb the maxi-mum output of the wind farm during such a bottleneck. A nominal power of around 12 MW was also selected for the turbo-generator.

In co-operation with the Schleswig-Holstein State Office of Agriculture, Environment and Rural Spaces, a suitable site for a cavern was sought in the direct vicinity of the wind farm. The ground geology here allows storage pres-sures of more than 100 bar.

Following economic optimization, the storage capacity and storage system operating pressure were found to demand a cavern size of around 50,000 m³ at an operating pressure of 120 bar. The operating pressure can fluctuate between 110 and 120 bar. In comparison with the use of natural gas caverns, both the volume and the pressure range are low and easy to control.

Blocks made from a special polymer-reinforced concrete were chosen as the thermal storage medium, largely based on the existing data from such concrete storage systems and their simple technology. Other available storage tech-niques, such as pressurized water tanks and latent heat storage systems (melts), were rejected on account of reservations regarding safety or process, but are conceivable in princi-ple. The blocks are heated to around 300°C during the compression stage.

The equipment: turbo-compressor, turbo expander and thermal storage system

In order to achieve the required pressures, an eight-stage radial turbo-compressor with dual intercooler and aftercooler and a driver output of 12.64 MW was chosen as the charging com-pressor. Thanks to the integrally geared design, with which cooling is theoretically possible after each compression stage, this is not a technical challenge.

To achieve the maximum storage efficiencies, a combination of four radial and twelve axial turbine stages was chosen for the turbo expander (electrical output 11.24 MW). Radial turbines are often more efficient at high oper-ating pressures, while the axial design is good for large volumetric flows close to atmospheric pressure.

As it is also possible to construct the radial turbines in an integral gearbox design, the compressed air can also be heated immediately after each stage. This allows optimum use of the stored heat created during compression. A central motor/generator can be connected to both the compressor and the expander via an active coupling. Experience with similar machines indicates an expected reaction time of less than five minutes from standstill to full load.

Equipment with variable inlet guide vanes (com-pressor) or inlet nozzles (turbine) enables load change rates of several percent per second to be achieved. In addition to the pure continuous storage of the wind power, this also enables par-ticipation in the market for primary operating reserves – an economic advantage.

Storage efficiency of almost 70 percent

The gross power quantity of 126 MWh used for the compression results in a net power quantity of 89.9 MWh. The study thus resulted in a calcu-lated mean efficiency of 66% for the A-CAES power plant. This A-CAES application therefore lags behind lithium-ion batteries and pumped storage power plants in terms of efficiency, but is considerably more efficient than power-to-gas or a hydrogen storage system.

Comparing the cost-effectiveness of storage technologies

At a conservative estimate, the price for the complete installation of the storage system is around €425/kWh. With regard to the total investment, the A-CAES storage technology using a salt cavern exhibits an enormous degres-sion rate as the storage capacity increases.

This is hardly surprising, because the initial drill-ing required in order to excavate the cavern accounts for around 30% of the total costs of this case study. The specific investment for a sys-tem with twice the storage capacity drops to around €330/kWh.

Whereas the specific investments for pumped storage power plants lie within the range of between €40 to €180/kWh, the price for large lithium-ion battery storage systems is currently about €600/kWh. However, a development

towards around €360/kWh by the year 2020 is foreseeable. The prices for hydrogen storage sys-tems on a comparable performance scale differ widely; realistic prices start at around €600/kWh.

So the A-CAES technology looks positive. Com-parison with other storage systems shows that this application (11.24 MW, 89.9 MWh) is by all means realistic from an economic point of view.

Not only that: A-CAES has the system-related advantage of a theoretically unlimited number of cycles. While batteries and fuel cells age and lose both capacity and power, the mechanics

and the minimal shrinkage process of the cavern are the only limits on the lifetime of an A-CAES application. From experience, we know that such machines can easily last for 30 years, suggesting a long lifespan for the A-CAES technology.

This longevity is proven not least by the Huntorf power plant, which was built in 1978 and is still in operation today.

Alternative concepts:Underwater storage systems, tunnels, pipelines

Although the use of a cavern is proven technol-ogy, it limits the use of A-CAES to regions with suitable geology. In the same way that pumped storage power plants are found exclusively in mountainous regions, most cavern fields exist in northern Germany. This is an advantage for the storage of wind power, but prevents nationwide use. Alternative concepts for the storage of com-pressed air have therefore been developed. Among the most unusual of these are undoubt-edly the use of gigantic balloons on the sea bed, which use sea water as counter-pressure, and the re-use of a tunnel inside a mountain in Swit-zerland as an oversized gas cylinder. Smaller applications could make use of pipeline seg-ments, known as pipe storage systems.

There are also numerous alternatives for ther-mal storage. From water, ceramic structures and wax to thermal oil, any thermal storage system with an adequate temperature level is suitable in principle.

The great challenge now is to fit the various building blocks together so as to create an eco-nomically-attractive overall concept for the indi-vidual application. A-CAES is a technology that sparks the fantasy of many engineers, not least due to the many storage variants.

Electricity storage systems will become interesting from 2025

Despite the many reasons for optimism, the reality is that no installed storage system, whether battery, A-CAES or hydrogen, is cur-rently capable of working efficiently without state or EU subsidies.

The inundated electricity market currently rep-resents the largest hurdle: There is simply too much cheap, conventional electricity. Amortized lignite and atomic power plants continue to contribute large parts of the base load, while gas-fired or the now flexible coal-fired power plants switch in when the availability or con-sumption of green electricity fluctuates.

Electricity storage systems are thus solving a problem today that will only exist tomorrow. Only from an annual green electricity propor-tion of 40 to 60% will the remaining conven-tional power plants begin to struggle to ade-quately stabilize the grid. The 40 to 45% mark is expected to be reached in 2025. Seven years remain until then – a very short time for the construction of a nationwide storage infra-structure.

A-CAES – a tangible solution

Market-compatible efficiencies and costs, tech-nology and materials proven a hundred times over, and a theoretically unlimited number of cycles: There are plenty of advantages to the A-CAES electricity storage system.

With renewable energies set to contribute an ever greater proportion of the electricity gener-ated, the nationwide use of energy storage sys-tems will be inevitable sooner or later. A start-up aid such as the EEG (Erneuerbare-Energien-Ge-setz = Renewable Energies Act) would be a suit-able instrument for establishing the technology on the market. The development of photovoltaic and wind power since the 1990s shows just how well a project like this can work.

Innovative Vacuum Components Increase Efficiency and Safety in the Automotive Industry

Josef Karbassi

The highly automated production lines of the automotive industry require innovative air-controlled vacuum technology in a wide variety of areas. One example comes from the press shops, where the transfer of metal parts between the presses can be controlled by means of a decentralized vacuum system. The use of multi-stage ejectors with integrated release mechanism enables fast evacuation, good suction performance and rapid release. Specialized suction cups provide optimal adhesion to potentially oily automotive components.

Automated material handling plays a major role in automotive production processes. Vacuum technology increases efficiency and safety while reducing the cost of a non-value-adding process step.

Press-to-press transfer is a huge vacuum applica-tion in automotive plants. Metal sheets are transferred through a series of stamping presses that cut, bend and shape the sheets, forming them into car parts. This is an application domi-nated by air-driven ejector technology, a contin-uously advancing field that is increasingly leav-ing electro-mechanical pumps by the wayside.

There are two different approaches within ejec-tor development. The first is in the form of decentralized systems with one ejector for each suction cup; the other is the centralized approach, where centrally placed ejectors serve an entire gripper arm. Both approaches offer benefits and both can be tailored to suit specific requirements or circumstances.

Decentralization is gaining momentum

Recently, the decentralization option has gained popularity among automotive manufacturers, especially for use in high-speed transfer presses, including cross-bar presses, where speeds of up to 15–20 strokes per minute are not uncommon. However, while a quicker response and release time is one of the main benefits of a decentral-ized solution, the added weight of multiple ejec-tors on each gripper arm can impair the speed, and also lead to unnecessary wear and tear on robot arms.

This is why lightweight decentralized ejectors are increasingly making inroads on the market. The latest ultra-lightweight ejectors have been specially designed for endeffectors/grippers used in press-to-press transfer. Due to the extreme vibrations associated with this applica-tion, mounting and installation interfaces need to be very strong and robust, and comply with industry standards in order to facilitate retrofit-ting in tooling systems.

Multistage ejectors preferred

To ensure the shortest possible release time, it is particularly important that the vacuum is bro-ken down quickly for suction cups with a diame-ter of up to 125 mm. Using multistage ejectors rather than single-stage ejectors will ensure a faster evacuation time, better suction capacity and a quicker release.

Low air consumption is another important performance target, with market-leading multi-stage ejector technology typically offering reductions of up to 25 percent, which translates into considerable energy and cost savings.

Reliable release mechanism is needed

Cycle speeds within an automated press-to-press transfer typically fall within the range of 8–20 picks/strokes per minute, and decentral-ized ejectors require a release function in order to meet such cycle speed targets. The latest ejec-tor models feature integrated release mecha-nisms and have been designed with ports for compressed air and vacuum in-line, enabling them to be mounted directly onto the hose, close to the point of suction.

The release mechanism can be either automatic, with no need for a secondary compressed air hose, or, alternatively, can be controlled by pilot compressed air. As it is not uncommon to sense vacuum on one or two units per endeffector/gripper, it is useful if optional vacuum sensing ports are also available.

Compact ejectors with integrated controls

So-called compact vacuum generator systems integrate controls such as valves, switches and sensors, and represent a more centralized approach. They are compact and are ideally suited for use in robotic applications in space-constrained installations. However, cen-tralization and the integration of such special-ized functions and technologies have pitfalls: if one part fails, the entire system fails.

It is therefore notoriously difficult to maintain a steady voltage in a system made up of several power-draining sub-units. If the voltage level drops too low, a valve might fail to open or close. On the other hand, a sudden surge can result in the catastrophic loss of a sensitive vacuum switch or sensor. Hence, it is essential that cen-tralized and highly integrated systems are designed with attention to detail and use state-of-the-art components, ensuring maximum operating time for the users.

Configurable approach offers flexibility

Configurable compact systems that allow users to choose from a wide variety of optional and/or customized pneumatic and electrical interfaces, valves, switches, and other features are particu-larly useful, as this allows tailoring the units precisely to individual manufacturing require-ments and budgets.

Such flexibility offers numerous opportunities for substantial cost savings. A compact and often modular, or even stackable, design allows the ejector units to be integrated into existing production lines without the need for modifica-tions, offering hassle-free installation that saves users both time and money.

The most advanced systems offer additional spe-cialized features, such as the amplified blowoff and the generic IO-Link for smart sensor and actuator communication. These features already meet the requirements of the next generation, the so-called Industrie 4.0, in which the Indus-trial Internet of Things (IIoT) is implemented.

Durable friction cups are essential

Dedicated suction cups that provide enough friction to enable optimal grip on potentially oily metal sheets and automotive parts are additional essential prerequisites in automated press shops. Emerging market requirements call for safer sheet metal handling and maximum hold on parts with a concave or convex surface.

A superior grip enables an increased number of strokes per minute in stamping, cutting, bend-ing, and punching machines, making for more cost-effective and productive press shops. Cups

that combine the properties of polyurethane with those of rubber display exceptional elastic memory and press oil resistance. These charac-teristics enable them to keep their shape and remain in good working order.

Disassembly enables maintenance and service

The ability to open and disassemble automation equipment enables faulty components to be exchanged and is a guarantee for uninterrupted production. It is essential that the equipment can be dismantled to allow its main compo-nents to be serviced and maintained to a high standard.

Although some systems are designed to be resil-ient to dust and dirt, at some point, cleaning will be necessary. Hence, cleanable vacuum filters should be used wherever possible and extra-large filter areas will also help to raise the bar for reliability. And a reliable system makes for a pro-ductive press shop – an excellent start in the race towards the next generation of automotive plants.
