grundfos INDUSTRIAl SOlUTIONS

The reasons for choosing Grundfos E-solutions in industrial applications are many. The advanced functionality offers extensive possibilities for complete process control just as significant energy savings can be gained by controlling the pump’s speed according to demand.

The E in E-solutions is synonymous with electronic control and energy savings. And you are guaranteed instant system improvement when you go for an E-solution. The unique all-in-one solution, pump, motor and integrated frequency converter, is packed with intelligent features that make installation, operation, and service exceptionally easy and performance much more efficient and reliable. The compact, integrated design comes with one drive for the entire world and complies with all international standards.

Go green with ESustainability is at the very heart of Grundfos and our full line of E-solutions is just one of many contributions to a greener world. Using E-pumps in your system, combined with correct sizing and the right control strategy, you can achieve significant energy savings – depending on your load profile up to 60% – because the pump is performing according to demand. We were the first pump manufacturer in the world to market a pump solution with built-in frequency converter and we continue to use our experience to break new ground in E-pump technology. To offer you the most valuable solutions.

Supreme speed controlSpeed control is an essential part of the supremacy of an E-solution. The frequency converter simply adjusts the pump’s speed according to the actual demand to offer a variety of benefits:

> Energy savings Speed control reduces energy consumption – and CO2 emissions.

> Increased comfort Speed control can reduce the noise from the system and the soft start feature eliminates water hammering.

> Reduced total cost Speed control can replace regulating valves, sensors and process equipment, and the quick installation contributes to bringing down the total cost.

> Longer life Reduced speed decreases the stress on the motor and prolongs the system’s life – as does the advanced integrated protection of pump, motor and electronics.

Customisation your wayWith an E-solution your pump can be perfected to suit even very detailed requirements. The customisation options include choice of materials, connection options and special software. The latest advances in software allow our designers to target your specific challenges very, very specifically.

System upgrade with standard pumpsVirtually any conceivable application can be upgraded with a standard pump from Grundfos’ comprehensive range. The pumps can be built to specification, thanks to the large variety of sizes, materials and designs. Whether the system is intended for heating, air-conditioning, water supply, pressure boosting or industrial processing you are guaranteed to find a pump that will successfully improve both control and cost effectiveness. On the following pages we go into more detail with selected applications but naturally our E-solution programme is compatible with a much wider range of applications.

Customise to go furtherif a standard product is not enough to cover your specific needs customised software is available to take your system upgrade even further. Customised software enables you to embed exactly the functionalities you want in your pumps – and to change the way they perform:

> Pump curves can be stretched and bent> inputs and outputs can be dedicated > Advanced functions and set-up can be selected> A variety of user interfaces can be chosen> Plus much more.

PC tools at your disposal if you wish to carry out adjustments yourself we provide a dedicated PC-based programming and monitoring tool. This gives you full access to optimising your software in any way you want. We are also more than happy to provide customised code if you prefer to leave the programming to us. Backed by decades of experience we know the challenges you face and are able to provide you with solutions that will meet them.

Your challengeYour solution Whatever your requirements Grundfos has got them covered. Choose a standard E-product, let us adjust the standard product to suit your specific requirements or include us in the development process from the very beginning to get a fully customised solution for your system.

in washing and cleaning applications customised software allows the pump’s RPM to be practically doubled. The increased speed, also referred to as over-synchronous operation, translates into greatly increased pressure and means you will get the high pressure you need from a significantly smaller pump. This can be achieved because the pump does not need to perform across the full pump curve. instead, the software lets the pump operate only within the necessary band with perfect precision.

E-solutions are the obvious solution to a variety of challenges encountered in temperature control applications, where regulating temperature is often crucial to ensure efficient processes. in addition to peace of mind, the E-solution may provide you with significant energy savings.

> Constant feed temperature E-solutions ensure a constant feeding temperature, for example for heat exchangers or in assisting chemical or biological processes.

> Constant return temperature E-solutions can help ensure that boilers and heat exchangers do not operate below recommended operating temperature.

> Regulating differential temperature Set the E-solution to regulate the differential temperature across a heat exchanger, hydronic heating system or cooling tower to maintain a constant temperature for secondary regulating devices.

> Constant flow regulation E-solutions keep the flow constant to optimise the performance of the heat exchangers when attached to other regulating equipment.

Stable steam generation is vital in any boiler feed application. This requires a constant water level in the tank, which can be maintained efficiently by means of an E-solution. With a combination of sensors and customised software it is possible to maintain the water level. The pump speed is automatically adjusted to keep a constant level in the tank which in turn ensures optimum steam generation.

E-solutions are ideal for optimisation of industrial booster systems, enabling both parallel and serial operation of speed-controlled E-pumps. By means of an add-on card integrated in the MGE terminal box the entire system can operate with no need for an external panel. Communication between the pumps is carried out via GEnibus.

Boiler FeedRemoves the need for regulating valves

Control unitThe frequency converter efficiently controls the pump speed and adapts it to actual demand. The result is stable operation and reduced energy consumption. Choose between the wall- mounted CUE frequency converter or the MGE variant which is integrated in the pump’s motor.

Motor proteCtionThe electronic motor protection, MP204, protects the motor from overload, no load, overvoltage, undervoltage and other variations in the power supply in order to avoid expensive downtime.

puMp proteCtionThe liqTec sensor prolongs the pump’s life by checking the temperature around the shaft seal and for presence of liquid. in case of dry-running the liqTec function automatically shuts down the pump before any damage is done.

Efficiency meets innovation to create astounding electricity savings

Putting sustainability first, Grundfos has initiated “Meet the Energy Challenge nOW”. The purpose of this initiative is to position pumps on the global climate agenda and to make a wide range of stakeholders within different industries aware of the fact that energy savings and CO2 reductions can be obtained by implementing already available technology. Pumps represent a massive and hidden potential for savings, in both energy and cost. With 10% of the world’s electricity consumption used for pumps, optimisation of pump systems evidently represents untapped potential. As a matter of fact it is possible to save as much as 4% of the world’s electricity consumption if everybody switches to high efficiency pump systems.

As the pioneers of this agenda, Grundfos has developed the Grundfos Blueflux® label. Motors and variable frequency drives bearing this label for pumps certify minimal electricity usage while ensuring top-of-the-line performance and reliability. Grundfos Blueflux® is the result of constant advancements in integrated motor technology and is designed to continuously deliver the very highest possible level of efficiency.
