We report about the State of the Industry in our annual January issue to gain insight into market trends,

obstacles, concerns and growth potential. As we highlight corporate capabilities this month (page 15), we decided to explore an industry update.

Is the economy really improving? “The consensus is ‘Yes,’” according to Grundfos Pumps USA President Dennis Wierzbicki. “But it will be a slow climb. Inventories and cash management continue as they did in 2009. Manufacturers, distributors, wholesalers and contractors continue to manage inventories closely, which puts a premium on those who have inventories and can respond to market needs.

“As usual, certain market sectors are show-ing signs of improvement. Even residential homes are beginning to move in certain states, as well as specifi c industrial markets. 2010 will continue to be a slow climb for the industry, but optimism for the long term also continues.”

The Gulf of Mexico oil spill has signifi -cantly slowed offshore activities and suggests continued investments in onshore activities in North America, says Weir Oil & Gas Division VP of Business Development Bill Tipton. “Economic recovery in the U.S. will continue to support sustainability of current rebound oil & gas market trends (drilling, well comple-tions, etc), and pricing will refl ect higher energy

demands to support recovery,” he says.“Investment in technology innovations

with a focus on more durable products is criti-cal to support the horizontal/directional drilling with hydraulic fracturing markets. We expect pricing improvements to continue with service companies in the North American sector.”

From the perspective of the end user, “Vendors and reps seem to have gone one of two ways,” explains Brian Cummings, E/M trainer for Washington Suburban Sanitary Commission. “Some have decided it is time to tighten their belts. Those who have not down-sized are falling all over themselves and being as helpful as they can with anything they can. It is like night and day.

“Also, things like automation, simpler and less time-consuming maintenance, reliability and longevity are more important now than ever. Unfortunately, for the short-sighted pur-chaser, the importance of keeping a low initial cost has increased. When it comes to develop-ing training material you can only get two out of three of the following: good, fast or cheap.”

Pumps & Systems will continue to keep an eye on the health of the pump industry. Let us know what you are experiencing in your busi-ness.Best Regards,

AC Circuit Loads

Last month we discussed the relationship between volt-age and frequency and tried

to make that somewhat complex three phase sine wave a bit more understandable. h is month we will quickly look at the load types that comprise a typical AC circuit.

h ree basic loads occur in AC circuits—resistive, inductive and capacitive (and various combina-tions of the three). As it sounds, a resistive load consists purely of a resistance. Electrical resistance is simply a measurement of the opposition to the passage of cur-rent (electrons). Resistance is directly proportional to the internal resistivity of the material and its length and is inversely proportional to its cross-sectional area. Resistive circuit examples include water heaters, irons, electric ranges and even incandescent lighting—almost anything that is designed to generate heat.

Inductive loads, on the other hand, produce induced cur-rents that oppose the l ow of primary current in the circuit. h is opposition to current change is dif erent than resistance and is called reactance. Inductive circuit examples include electric motors, generators, solenoids and transformers.

Capacitive loads act exactly opposite of inductive loads and retard the l ow of voltage. Examples include true capaci-tors (condensers), piezoelectric devices and metal oxide semi-conductors. h ese three loads have a very dif erent ef ect upon the l ow of voltage and current in an AC circuit.

Resistive CircuitsIn the case of a resistive load, AC loses much of its mystique and behaves much like DC. Although there is no such thing as a purely resistive AC circuit, many are close enough that they will follow Ohm’s law (I = E/R where I is current in amps, E is voltage and R is resistance in Ohms). Figure 1 shows a simple circuit with a 60 ohm resistance fed by 120 VAC.

Using Ohm’s law, we can calculate the current in the circuit to be 2 amps. h e power that the circuit dissipates (as heat) is simply the product of volts times amps, or 240 watts. If we did not know the voltage in the circuit, we could calculate it by measuring the current. If I is 2 amps, then E = IR or 120 V. h e reason that these calculations are so simple can be explained by the relationship of the voltage, current and power curves seen in Figure 2.

Figure 2 shows the l ow of voltage (blue), current (red) and power (green) in a simple resistive circuit such as the one shown in Figure 1. In a purely resistive circuit, voltage and current rise and fall together in a synchronous fashion. h e reason this occurs is that a resistance continuously opposes the l ow of current in a circuit regardless of whether the volt-age is DC or AC. Because of this continuous opposition, current l ows in phase with voltage. At every point above

the x axis, both voltage and current are positive, and at every point below the x axis, both are negative. h e green curve represents the power (in watts) dissipated as heat in the circuit and is the product of the voltage and current at any point on the x axis.

Note that the power curve is always positive except at those points where voltage and current pass through zero. Even when both cur-rent and voltage are negative, power is still positive because the product of two negative quantities results in a positive quantity. h erefore, power is consumed at all points except those where the waves pass through zero. Even though the wave forms are still a bit complex, their synchronous rela-tionships make a resistive circuit rela-tively understandable.

Inductive CircuitsInductive loads could not be more dif erent. A new dimension, known as inductance, and a new quantity, known as reactance, cause this type of circuit to behave in a fashion dif erent from the simple resistive load. h is dif erent behavior is due to the positive and negative l uctuation of the AC sine wave.

Figure 3 is an example of a simple inductive circuit that consists of an AC source connected to an inductor. In this example, the inductor is a coil of wire consisting of several loops. When AC l ows through a coil, a magnetic i eld is cre-ated in and around the coil, and it increases and decreases in proportion to the primary current l owing through the circuit. h is changing magnetic i eld induces a secondary voltage in the coil, which gives rise to secondary current that opposes the primary current. h is process is known as self induction or self inductance. In a DC circuit, this opposition arises only when the voltage is switched on or of . Once a DC inductive circuit is energized, current l ows steadily in a single direction and no secondary cur-rent is induced.

Figure 4 (from Collaboration for NDT Education) provides a clearer picture of how this occurs. In this example, primary current (red) is shown l owing clockwise through the loops in the coil. Its l ow gives rise to a magnetic i eld (blue) in the i rst loop. h e magnetic i eld induces a secondary current (green) in the second loop that

l ows counter clockwise. h e counter-clockwise l ow of the secondary cur-rent (often called back emf) opposes the normal l ow of current and causes current to lag voltage in the circuit. h is opposition to a change in pri-mary current is known as reactance.

Figure 5 shows the l ow of volt-age (blue), current (red) and power (green) in a purely inductive circuit. h e opposite l ow of the induced secondary current impedes the l ow of primary current and causes it to lag voltage by 90 deg or one quar-ter cycle. h e power curve shows the overall ef ect of reactance. Note that it is positive during every other quarter cycle and negative during the quarter cycles in between. h e RMS values of the positive and negative portions of the curve are also equal.

During the positive quarter cycles, the circuit is storing power as the magnetic i eld and during the negative cycles the i eld dissipates and returns power to the source. h erefore, a purely inductive circuit con-sumes no energy. h e degree to which the secondary current or back emf impedes the l ow of primary current is called induc-tive reactance (XL) and, like resistance, it is measured in ohms. Shortly, we will show how inductive reactance can be used to help redei ne Ohm’s law for use in AC circuits.

Capacitive CircuitsWe will end this part with a quick discussion of purely capaci-tive circuits. A capacitor is a device that can store an electric charge, and the energy stored is equal to the work done to charge it. It consists of two plates separated by an insulating sheet called a dielectric. When connected to a DC voltage, one

plate acquires a negative charge while the other acquires a posi-tive charge, but no current l ows through it once the capacitor is fully charged. If that same capacitor is connected to an AC voltage, an alternating current will l ow continuously.

Figure 6 is a simple, purely capacitive AC circuit. A charge cannot l ow between the two plates since they are insulated from each other, so it seems a bit unusual that a continuing AC current exists in the circuit. h e reason current l ows in a capacitive circuit when AC is applied is because those charged plates change their polarity each time the AC sine wave reverses direction. h is causes the charge to l ow to and from the two plates. h erefore, the two plates of the capacitor are con-tinuously charging and discharging and current l ows continuously.

Figure 7 shows the l ow of volt-age and current in a purely capacitive circuit. h e l ow relationship is exactly opposite that of the inductive circuit and current is seen leading voltage by 90 deg. Although power is not shown, it would look like the power curve in the inductive example, and the cir-cuit consumes no power. h e degree to which charging impedes voltage is called capacitive reactance (XC), and it is measured in ohms like resistance and inductive reactance.

RLC Circuits and ImpedanceAlthough some circuits consist of a single load type, most are combinations and are referred to as RLC circuits. Because of the inl uence of the inductive and capacitive loads, Ohms law (E = IR) does not apply. Instead resistance (R) is replaced with impedance (Z), and impedance takes into account both induc-tive and capacitive reactance. h e equation takes the form of E = IZ and Z is equal to √R2+(XL-XC)2 (where R is resistance, XL is inductive reactance and XC is capacitive reactance). h e square root sign encompasses the entire equation. As you can see, XC is subtracted from XL as its voltage lagging ef ect com-pensates for the current lagging ef ect of XL. If the two are equal, they cancel each other, and the circuit is purely resistive. In circuits where XC is greater than XL, the negative sum is squared and produces a positive number that is added to the square of R. h e square root of that sum gives us the circuit’s actual impedance.

Power factor describes how ef ectively the loads in a circuit can use the power available and is directly related to inductive and capacitive reactance. We will not discuss power factor here because I have covered this important AC topic in the past. Please see my June and July 2007 P&S articles on power factor for a detailed discussion.

Next month we will explore mutual induction and the versatility of that mutual induction machine known as the transformer.

When the motor amps are kicking a unit ol ine, the i rst question is whether the motor or the pump is the problem.

Before any sophisticated troubleshooting methods are applied, most experienced mechanics simply feel the units to see if the motor (or pump) “feels hot,” “runs rough” or “does not feel right.” h ere is little science behind these phrases, but years of experience and intuition often get the job done well. In fact, relying on too much technology may play tricks on you, as I encountered recently.

A main inl uent wastewater system consisted of six pumps, with one or two typically operating on a normal (relatively dry) day (see Figure 1).

h e two-step starting sequence for these units involved getting the unit to 436 rpm, and then on to 511 rpm, after some stabilization delay time. At 4,160 volts, the motor trip was set at 89 amps. Normal, full-speed operation produced 54 mgd (million gallons per day) l ow, with 83 amps motor current. At these conditions, the pump developed 25 psi. Secondary motor windings were rated at 1,040 volts, 275 amps.

A “good” pump (#6) operated i ne at full speed, produc-ing rated l ow and pressure, with the amps at three phases showing good current balance of 83/83/83 amps. h e “bad” one could not get past the low speed region (436 rpm), showing 86/90/86 amps, which would delay the motor trip-ping. h e l ow was reading 31 mgd at 25 psi dif erential

pressure as maintained by the stronger #6 pump.My i rst check was to see if the pump l ow and head

corresponded to the lowered speed, as indeed is coni rmed in Figure 2. At 436 rpm, the pump intersected the 25 psi system curve at about 31 mgd, which is what the pump l owmeter was registering. In other words, the pump was hydraulically i ne.

My next investigation was how the pump and/or motor felt. By hand, the vibrations felt i ne, and the bearing hous-ings did not feel hot. To make sure, I did a quick, full spec-tral vibration measurement on both pumps’ housings (see Figure 3).

Expecting (hop-ing) to see signii cantly higher vibrations on pump #5, I was puz-zled to see the overall (RMS) level of vibra-tions at 0.075 in./sec for the (“good”) #6 pump, but only 0.047 in./sec for the (“bad”) #5 pump. h e “bad” pump had lower vibra-tions, yet it had higher amps tripping the motor.

As a side note, in practice, anything

Pumping Prescriptions

Figure 2. Pumps #5 and #6 performed hydraulically correct in accordance with the Affi nity Laws.

Figure 1. 600 hp (1.15 SF) motor is connected by a set of the segmental U-jointed shafting to the pump

at the bottom of the dry well.


below 0.1 in./sec (RMS, overall) would nor-mally not trigger a concern (the dif erence between 0.075 and 0.047 in./sec values is essentially academic), so both pumps, accord-ing to the overall vibration levels, would be considered non-problematic. Yet, #5 was trip-ping the motor.

My next observation was the unbalance of amps on unit #5 (86/90/86 amps), i.e., roughly 5 percent current unbalance. Although electri-cians did not feel the value of such unbalance was an issue, it was the only remaining issue I could see possibly causing the problem. My conclusion was to check the electric side i rst—motor, contactors, relays, etc.

Wrong! Electrical inspection showed no problems. h e pump rotor was i nally pulled. Surprise! h e nut holding the impeller was loose. h e impeller moved down and was rub-bing the wear rings of the casing by the impel-ler shroud. Furthermore, the shaft was slightly bent, as verii ed by the run-out inspection.

Conclusion

For medium- to high-energy pumps operating at low speed, vibration detection alone may not always reveal the root cause of the prob-lem. Low speed may also not reveal the prob-lem via elevated temperature of the windings or bearing housings. Additional power (amps) could be coming from the grinding away of the contacting wear rings, despite the fact that all other parameters of both pump and motor may remain at the acceptable (low) level. h is would be similar to the low vibration of a ver-tical milling machine slowly milling away a metal plate—at low RPM and low feed rate—running smooth, yet grinding metal away.

In retrospect, after closer examination of the vibration signatures, some clues perhaps could be seen in the discrete multiples of the harmonics (1X, 2X, 3X, 4X, etc.), which often suggest the presence of inter-nal component looseness. However, due to the overall values being so low and essentially within the noise level (noise is typically under ~0.02 in./sec), these peaks were disregarded as insignii cant.

P&S

Figure 3. Full vibration spectral analysis indicated low overall vibrations and spectral harmonics essentially within the “noise” level.

The origins of today’s Skinner Power Systems, LLC, date back to the years shortly after the U.S.

Civil War. It was early in the era of steam power. Inventors and entrepreneurs of the time were tinkering with new ways to harness steam power to run machinery to mass produce goods and bring economic benei ts to a growing nation.

Skinner Engine Company:

The Early YearsOne of those enterprising individuals was inventor Le Grand Skinner who, in 1868, founded the Skinner Engine Company and began building steam engines in a plant at Herkimer, N.Y. In 1873 he opened a manufacturing plant in Erie, Pa., and moved the company’s headquarters there not long thereafter. From Erie, Skinner had ample access to railroads and waterways to ship products to an expanding customer base.

Skinner’s product, the steam engine, converted the energy in steam to mechanical power by injecting steam into a cylinder to drive a piston back and forth. h is mechanical power was then used to drive other machinery. Early on, the i rm’s engines of various sizes and coni gurations attracted a large clien-tele from a wide range of applications including manufacturers, food proces-sors, lumber mills and paper mills. Not

one to rest on his laurels, in 1910 Le Grand studied unal ow (also “unil ow”) engines in Germany and returned to Erie to develop his own version in 1911. Skinner’s unal ow engines were its most widely sold design, working well in land-based and marine applications. In fact, during World War II Skinner unal ow engines were installed on more than 120 U.S. navy ships.

Skinner set high standards for prod-uct quality and performance by establish-ing an unconditional guarantee for his i rm’s products. If a steam engine failed to generate the promised power output when installed, the customer got to keep it without cost. It is reported that he never had to honor a guarantee for failing to meet the guaranteed performance.

h e company expanded under Skinner’s leadership for 54 years until his death in 1922. h e traditions of qual-ity products, solid customer service and innovation that were established at the company’s outset remained throughout these years and continued as the man-agement of the company passed i rst to Skinner’s son Allen, a shrewd marketing innovator, and then in 1949 to Allen’s son J. Le Grand.

Skinner Engine Company:

The Later YearsIn the 1950s, the company added indus-trial mixers to its product portfolio and was serving customers in Canada and South America in addition to the United States. But with the death of J. Le Grand Skinner in 1963, the Skinner Engine Company was sold to Patterson Industries, a Cleveland, Ohio, based company, which among other things manufactured a line of industrial pumps.

Around this time, Patterson also acquired the Dean Hill Pump Company, a manufacturer of steam turbines and industrial pumps, based in Indianapolis, Ind. Dean Hill had a long history and favorable reputation, having been formed after World War I when the Hill Turbine Company merged with Dean Brothers Pump Company to become the Dean Hill Pump Company. Over the next four decades Dean Hill manufactured nearly 20,000 turbines and pumps. By the early 1960s, Dean Hill expanded to overseas markets and established an international presence by granting a manufacturing license to Manubat, a company located in France.

In the mid-1960s, Patterson closed the Dean Hill plant in Indianapolis and transferred all pump and turbine manufacturing to the Skinner operation in Erie. Now Skinner had four product lines: steam engines, steam turbines, pumps and industrial mixers.

With the exception that both steam engines and steam turbines use steam to create mechanical power, the two prod-ucts are totally dif erent from each other. Developed at the turn of the twentieth century, a steam turbine has no cylinder or piston. It converts the energy in the steam to mechanical power by injecting the steam into a case containing a bladed wheel mounted on a shaft. Steam is chan-neled and directed against the blades on the wheel causing the wheel to turn.

In 1968, Banner Industries, another Ohio-based company, acquired Patterson Industries. In 1973 Banner reorganized its operations, moving all pump pro-duction from Skinner in Erie to a plant in Georgia. h is left Skinner with the steam engine, steam turbine and indus-trial mixer product lines. By the mid-1980s, Banner Industries was struggling. Although Skinner was proi table, Banner decided to sell the Skinner operations in Erie.

In 1986, Gerald A. (Tony) Ryan, an Erie entrepreneur, and several other inves-tors formed Ryco Holding, Inc., which acquired Skinner from Banner Industries. Ryan, the CEO and principal owner of Skinner Engine Company, guided Skinner into the global export business for turbines and turbine generator sets. Under Ryan’s leadership, Skinner’s total annual sales rose from about $10 million to $17 million by the late 1990s.

In 1998, Ryco Holding, Inc., sold Skinner Engine Company to American Commercial Holdings, Inc., a Lexington, Ky.-based company. Unfortunately, a couple of years later a worldwide reces-sion took its toll on Skinner’s sales, and in 2002 American Commercial Holdings decided to sell of the Skinner product lines.

Skinner Power Systems,

LLC: TodayIn 2002, Klaus P. Fischer, a retired vice president of Elliott Company in Jeannette, Pa., was looking for a new business opportunity when he learned of Skinner Engine Company’s turbine capa-bilities and determined that there was a sales growth opportunity for Skinner turbines. With several associates, Fischer formed Skinner Power Systems, LLC. He wanted to continue the “Skinner” name because it represented a lengthy tradition of reliable products, innovation, fair price and support for customer operations.

h ese were the values that Fischer would incorporate into the new organization.

In November 2002, Skinner Power Systems, LLC, purchased the turbine product line from the old Skinner Engine Company. h e transaction included all of the Skinner and Dean Hill turboma-chinery technology and sales and service. h e new i rm set up its headquarters and manufacturing operations at its current Erie location in a modern 14,000 sq ft facility.

Today, the current Skinner steam turbine line includes models that range from 0.5 to 3,000 hp (0.3 to 2238 kW) and all pressures and temperatures to 900 psig and 900 deg F (63 kg/cm2g and 482 deg C) inlet and 175 psig (12 kg/cm2g) backpressure. Existing users of Skinner or Dean Hill equipment have a few unique options. Virtually any part for older Skinner or Dean Hill turbines, no matter where it was originally manufactured, can be sourced through the Skinner Power Systems facility in Erie, Pa. Equipment that may be half a century old can be replaced basically with the same type of turbine, with modern upgrades as a fac-tory standard. In many instances, the old Dean Hill turbines can be replaced with the Skinner SB series line, of ering the simplicity of ball bearing rotors, low ini-tial cost and exceptionally high reliability, with absolute minimum maintenance downtime.

Another major facet of its new equipment business today is packag-ing its turbines with other machinery, such as electric generators, pumps, fans and compressors. In particular, Skinner builds turbine generator packages up to 2 MW in size. Company specialists can recommend ideal system equipment con-i gurations and specii cations to satisfy customer operating objectives.

Additional services available from Skinner include repairing and rebuild-ing older units. All internal components can be replaced with new parts built to original specii cations. Upon completion of the re-building, the units are tested with live steam, the same as for new tur-bine systems. Customers are supported by skilled technical support and service personnel that are dedicated to maintain-ing customer equipment reliability. Vital replacement parts can be supplied from its parts department on short notice.

h rough its years as a supplier of quality turbines, the i rm has supplied thousands of turbines to operate customer compressors, electric generators, pumps, mills, fans, blowers and other equipment. h e company’s customers include rei ner-ies, petrochemical plants, pulp and paper mills, food processing plants, steel mills, sugar mills, palm oil mills, and medical and educational facilities.

Time has not dimmed the commit-ment of today’s Skinner Power Systems to extend and further enhance those tradi-tions and values that were established by Le Grand Skinner more than a century ago.

Take, for instance, an outdated BB2 design Model HVC between bearing single-stage, high energy pump—histori-cally, a “bad actor” pump in many a rei n-ery application. h e owner had looked into a replacement, but why replace the old bad actor with a new bad actor? h e OEM of ered a current standard design pump that required base plate, suc-tion and discharge piping and motor changes at considerable cost and delivery approaching 48 weeks.

CLYEDUNION stepped in with our Flag Ship HOL design with the stif er shaft, 360 deg bearing housing all the current API 10th Edition pedigree. We custom built this unit to ‘Drop In’ the existing pump envelope. No base plate mods, no piping mods or drive motor moves, and this was done in 26 weeks.

For 29 years, Hydra Service, Inc., has met the pumping needs of people, cities and industries of the

Southeastern states. Hydra Service was started in the basement of its founder, F. J. Doyle II, in 1982 with two employees. Today, HSI has grown into a multimil-lion-dollar operation, a total of 65,000 sq ft located in three branches, whose 70 plus employees serve the l uid move-ment needs of Alabama, Florida and Mississippi.

“Jimmy” Doyle, the company’s owner/president, attributes HSI’s current success to the employees and the service they provide. “It is the people who have worked for the company who are respon-sible for our growth and success.”

How does such a thriving concern get started? In 1982, Hydra Service had one submersible pump line. By 1984, HSI started a partnership with ABS that is ongoing. Hydra Service joined forces with another valuable manufacturer, Godwin Pumps, in 1991. Both lines have been the mainstays of Hydra Service’s extensive product line.

In 1992, the i rst 5,000 sq ft building was built on three acres in Warrior, Ala., and became the main headquarters, now measuring 50,000 sq ft on 20 acres. h e Robertsdale, Ala., (Florida Panhandle) branch was added in 1995 with 5,000 sq ft on three acres, with plans to add a new 10,000 sq ft facility in the near future. A third branch was opened in 2006 in Pelahatchie, Miss., with a 10,000 sq ft sales/service shop on four acres.

Commitment to Qualityh e most recent expansion is at the main headquarters with a 7,500 sq ft addition, where a new 32,000 gallon test tank was installed. “h is tank is state-of-the-art. We test pumps and pumping stations that we build or repair, ensuring com-plete customer satisfaction.” h e tank has the capacity to test up to 350 hp with 14-in. piping, including a 14-in. l ow

meter with recorder. Controls for the test tank include a 460v VFD and a 230v VFD which enables HSI to run pumps at variable speeds. “h e test tank is so valu-able to the service of our customers that we have plans to upgrade the VFD drives to 500 hp.”

“Hydra Service just completed a rebuild of a 350 hp vertical turbine pump. It was tested in the new tank with room to spare!” h e tank also has guide rail brackets from 4 in. – 12 in. for the submersible pumps. A 10-ton overhead crane maneuvers the pumps within the shop.

Commitment to ServiceHydra Service prides itself on service, providing complete repairs and trouble-shooting on-site 24 hours a day, 7 days a week. With 36 service technicians, a 15-ton boom truck, tractor trailers, hot shots and service trucks (most equipped with cranes), the customers of Hydra Service can depend on getting the job done right. HSI’s service is backed by its own in-house 508A & 698A UL Listed Panel Manufacturing Shop, Rewind Shop with a VPI system, and a full-ser-vice Machine Shop operated by certi-i ed CNC machinists and welders. “Our

SERVICE sets Hydra Service apart from our competitors. We back what we sell or rent, and our customers know it.”

From industrial mining operations to the waste-water needs of municipali-ties, Hydra Service provides a full-range of products and services, including pro-cess equipment, non-clog submersible pumps with premium-ei ciency motors, pump station control panel management systems, dewatering equipment and turbine pumps. HSI has a large rental l eet—both electric and diesel pumps, 2 in. to 18 in.—and several thousand feet of HDPE and Bauer pipe.

SPX—Where Ideas Meet Industry



Synchrony, Inc., is a technology leader in the development and delivery of magnetic bearings and

high-speed motors and power conversion systems. h e company brings a spirit of engineering excellence, bold innova-tion and creativity to improving rotating machinery.

Clean. Effi cient. Reliable.h ese attributes are often used to describe magnetic bearings. With no need for lubricants, with no mechanical wear or friction and with the capability to tailor bearing characteristics to opti-mize performance, it is no wonder that there is growing excitement about using magnetic bearings in high-performance machinery. h is is especially true today, where there is much focus on improv-ing the utilization of energy using eco-friendly technologies.

h e truth is that the advantages of magnetic bearings have been known for a long time. h e principle of using electro-magnets, sensors and active electronics to suspend objects without mechanical con-tact was demonstrated by Jesse Beams at the University of Virginia in the 1950s. Despite the long history of magnetic bearings, today only a small fraction of rotating machinery is supplied with mag-netic bearings.

What Is the Reluctance

Toward the Widespread

Use of this Technology?We believe that in the past, the accep-tance of magnetic bearings was impeded because the bearings did not meet basic

engineering criteria related to perfor-mance, simplicity, size and cost.

PerformanceMagnetic bearings must be uncondi-tionally stable for just about any operat-ing condition of the host machine. h is includes conditions of high dynamic loading caused by surge, stall, ingestion of liquid slugs, cavitation, motor electri-cal faults and other transient conditions.

SimplicityMagnetic bearings must be easily inte-grated into new and existing designs of rotating machinery. To facilitate this inte-gration, the bearings should be of ered in

standard sizes, be easy to mechanically and electrically integrate into the machine and be accurately modeled using standard techniques. Additionally, the bearings should be simple to optimize and operate and interface with other plant systems for process control, health monitoring and trending. h e size, quantity and length of cables between the controller and the magnetic bearings should be kept to a minimum. h e overall complexity of the magnetic bearing should be hidden from the machine designer or end user.

Sizeh e magnetic bearings should be as small as possible to facilitate integration into the rotating machine. h e magnetic bearing

controllers should be miniaturized so that they can be mounted on or near the machine to reduce the length of cables, reduce EMI, reduce the time to calibrate the bearings and reduce the footprint of the magnetic bearing system.

Costh e decision to use magnetic bearings instead of oil-lubricated bearings should be economically justii ed based on a return on investment (ROI) analysis of acquisition and operating costs. h e value of the magnetic bearing system is the elimination of the oil lubrication system, the reduction in process down-time, longer machine life, improved machine ei ciency and the reduction in maintenance costs.

At Synchrony, Our Passion

Is to Massively Increase

the Use of Magnetic

Bearings for Existing and

New Applications.h rough a series of design innovations that began when Synchrony was created in 1993, we have systematically improved the performance, simplicity, size and value of magnetic bearings to the point that our systems are now used in many new applications that were not possible just a couple years ago. We are seeing rapid acceptance of our products as more customers experience the attributes of magnetic bearings—clean, ei cient and reliable.

Synchrony has developed a suite of educational material on its website, www.synchrony.com, where you can learn more about the company, magnetic bear-ings technology and the advantages of using high-speed motors and generators for improving your rotating machinery applications.

Just about all industrial machines or processes are driven by an electric motor. If you monitor the load on

the motor, it will give you valuable information about what is happening inside the machine or process.

Mixers or AgitatorsWhen viscosity changes, the load on the mixer motor also changes. A “load pro-i le” of a good batch provides a template that future batches should take.

Pumpsh e more liquid that you pump, the more power it takes. However, if the pump runs dry, the power drops right of . Many pumps don’t do well when they run dry. A load control can stop the pump before expensive damage is done.

h e best way to know the load is to measure the motor power. (Power is mea-sured in horsepower or watts.) It gives you a straight line, so it works well even when the motor is lightly loaded.

h e power sensors that we make measure the motor load (Horsepower or Watts) and send a signal to meters or computers.

A load control also measures motor power, but it has built-in relays and set points. You can adjust the set point so that when the load on the motor reaches the set point, a relay will trip.

Load Controls, Inc., supplies the controllers and monitors you need to measure and monitor motor power. For example for pump protection, our PMP-25 Pump Load Control guards against dry running, cavitation and

overload. It monitors true pump power for

maximum sensitivity and the power, trip points and delays are all displayed. h e enclosure is small enough to i t on size one starters and can be door, panel or wall mounted. Two relays, plus a 4-20 mA output, give you valuable load information. Give us a call for your free 30-day trial.

Warren Rupp, Inc., is a world leading manufacturer of Air Operated Double Diaphragm

(AODD) pumps serving a variety of markets—including chemicals, paints, food processing, electronics, construc-tion, industrial maintenance, utilities and wastewater. With the broadest range of pump sizes, types and models, the company markets brand names—such as SANDPIPER®, Marathon®, Versa-Matic®, Blagdon®, and Pumper Parts®.

In August 2010, the company unveiled its highly anticipated AirVantage Series. AirVantage is a revolutionary, new, energy-saving technology that reduces air consumption by as much 50 percent when compared to traditional air-operated double diaphragm pumps. AirVantage features an adaptive (smart) technology that adjusts as process condi-tions change to maintain constant l ow

capacity without manual operation or adjustment.

Available for two- and three-inch line sizes, AirVantage pumps are compat-ible with Sandpiper standard and heavy duty pumps and Versa-Matic E-Series bolted and clamped pumps.

By using AirVantage, facilities are able to run AODD pumps more ei -ciently. h is translates into several benei ts for the operator, such as direct energy sav-ings from running fewer air compressors and dedicating more air volume to other

areas of a facility for greater productivity. Plus with AirVantage, companies may be able to avoid capital expenses related to adding air compressors to address low air compressor capacity.

Warren Rupp, Inc., is a unit of IDEX Corporation, a global l uidics leader serv-ing high-growth, specialized markets. h e company uses a worldwide network of independent, factory-authorized dis-tributors to sell their pumping solutions. Warren Rupp pump brands are sold in over 60 countries and may be found in nearly every major trading area around the world.

Sims Pump Valve Company, Inc.

The year was 1919. h e place was the Red Hook section of Brooklyn, N.Y. Admiral Sims

and his brother launched the Sims Pump Valve Company by inventing a valve for

use in reciprocating pumps. From the outset, the company of ered a unique guarantee of customer satisfaction that continues to this day.

In 1945, the inherent clattering of

the reciprocating pump valve caused by the pump rotator pounding against the disk led the company to invent the Simsite® disk. Made from the company’s own patented structural composite mate-rial, it was one of the i rst composites on the market.

In 1955, recognizing that con-ventional metal impellers were subject to electrolysis, corrosion, erosion, and unbalance problems when used in ser-vices such as salt or brackish water, Sims introduced Simsite casing rings and impellers. Outlasting traditional bronze and stainless components by years, they extended the entire pump life.

Major Products/ServicesSims has been producing Simsite advanced composite pumps, impellers and wear rings since 1961.h ese pumps and parts have many advantages over metallic ones, including increased perfor-mance, lighter weight (1/6th metal), cor-rosion, erosion and cavitation resistance, self-lubricating characteristics and the Simsite advantage—the ability to adjust performance, increase or decrease l ow rate, head or NPSHR.

h e company’s products include a complete range of precision-machined pumps, wet ends and replacement parts for the ANSI, vertical-sump and verti-cal-turbine markets. Sims also upgrades impellers.

At Sims, two traditions still go hand-in-hand: h e guarantee behind each of the company’s products and the more than 80 years of service and experience that back it up.

BaseTek, LLC, the market leader in innovative polymer concrete baseplates for the rotating equip-

ment industry, recently celebrated the casting of its 10,000th standard pump baseplate. BaseTek of ers a complete line of pre-engineered and custom base-plates, along with accessories for all types of process pumps and specialty rotating equipment.

Bases are manufactured of Zanite®, a proprietary polymer concrete material. It is a blend of pure silicon dioxide ceramic quartz aggregate and high strength epoxy resins. BaseTek bases deliver a solid, unmatched surface l atness of 0.002 in. per ft, and provide physical proper-ties that surpass lower grade vinyl ester composites and i berglass. h ey are cor-rosion resistant and of er higher tensile, l exural and compression strength than vinyl ester.

Industry experts believe a solid, l at mounting surface is the i rst step in estab-lishing and maintaining shaft alignments, minimizing vibration and increasing the reliability of any piece of rotating equip-ment. BaseTek’s polymer concrete bases reduce grouting requirements and elimi-nate the problematic diaphragming and twisting that typically occur in common

steel designs. Superior corrosion resis-tance eliminates the need for periodic maintenance—such as scraping, priming and repainting—which is often required to prevent degradation to critical base-plate tolerances.

Stainless threaded insert locations are precisely cast into the polymer, provid-ing a secure and accurate hole location. Hole perpendicularity is maintained to prevent equipment from being “bolt-bound” and compromising i nal equip-ment alignment.

BaseTek’s state-of-the-art, 12,000+ sq ft manufacturing facility in Newbury, Ohio, USA, is a turnkey operation with a staf of industry experts. Balanced verti-cal integration allows for ei cient design-ing, manufacturing and inspection of baseplates to match any size and shape most applications demand. Computer-controlled batch mixing systems, pre-cision tooling and CMM inspection equipment ensure consistent quality and reliable castings.

VibrAlign sells, rents and services a full range of laser alignment and measurement tools. In addi-

tion, VibrAlign fi elds a team of highly experienced service providers who are respected as experts in vibration analysis, balancing and machinery alignment.

VibrAlign, Inc., is the U.S. dis-tributor of the Fixturlaser line of laser measurement and alignment systems. Fixturlaser AB has been in the alignment business since 1980. Twenty-six years ago Fixturlaser developed its fi rst laser align-ment system. Th e proof of Fixturlaser’s success is that, today, Fixturlaser sys-tems are used in more than 70 countries around the globe.

Our fl agship laser alignment system is the Fixturlaser XA. Th e XA is designed to get alignments done fast. . . really fast. Th e system incorporates on-screen

Flash® animations that actually walk the user through the alignment process!

Our newest system is the mid-range Fixturlaser GO. Th e GO refl ects Fixturlaser’s “Express Alignment” phi-losophy in its design and technology. Express Alignment recognizes that align-ment tools like the GO and the XA are not used every day by maintenance and service professionals. Th erefore, the GO and XA are designed with interfaces and functions that once learned are easy to remember. Th e user doesn’t have to re-learn how to perform an alignment every time he picks up the instrument.

Th e value end of the range is repre-sented by the Shaft Hog. Th e Shaft Hog’s live display means that you get instant feedback when shimming or moving the machines. Great accuracy and ease of use at an aff ordable price.

In addition to laser shaft alignment, we off er the Belt Hog sheave alignment tool. Th e Belt Hog’s dual lasers sit right in the pulley grooves where power is transmitted, which means that the Belt Hog delivers the best alignment possible. And the Belt Hog can be used without removing the belts or the belt guard.

We have personnel located in key cities throughout the U.S. and experi-enced service providers ready to travel whenever and wherever customers call. Whatever alignment or vibration prob-lems you face, VibrAlign can help.

Contact VibrAlign today to see how fast alignment can be.

Innovations like over-sized digital detectors, line lasers, and True Position Sensing (TPS). TPS allows the XA and the GO to compensate for both intended AND unintended movements of the moveable

machine made during the alignment process. The result? Alignments usually can be completed in just one set of horizontal and vertical moves without re-measurement in between. Now that’s fast.

Innovative technology in the Fixturlaser XA and GO means there’s no faster way to complete alignment!

Maintenance Minders

Is it becoming harder to i nd time to think instead of react? h e blistering pace of information bombarding us and

being requested drives us farther into the abyss of reactivity. It is continually harder to call “timeout.” But now more than ever, it is one of the most important things we can do in the midst of a problem. If we do not make time, problems will not go away. h ey will mount until they become emergencies requiring immediate attention and divert-ing us from proactive work.

How can we slow down, think logically about the causes of our problems and i nd solutions that actually save both time and heartache? h e answer was revealed to me through an experience years ago.

When I was a younger engineer, I was easily caught in the moment and ot en did not take the time to think, even though I had fewer responsibilities and distractions than I do today. I recall a particular pump problem that threw me headlong into the reactive loop and nearly cost me and my company sig-nii cant time and money. It created a lasting memory of how important it is to stop and think, no matter how much pressure we face.

I was project manager on the replacement of a cooling tower at a large integrated chemical manufacturing site (more than 20 dif erent plants with more than 2,500 employees). While the cooling tower did not serve the entire collective need of the site, it was one of the larger towers and served mul-tiple plants. h e existing redwood cooling tower was failing to meet demand, and had become structurally unsound. It had served out its useful life and replacement was required. Because of production demands from the af ected plants, our target was less than eight hours of cooling tower downtime to make the switch from the old tower to the new multi-cell modular towers erected next to the existing tower.

Due to the limited downtime window and to minimize new capital expenditures, we elected to reuse the existing “hot well” sump and pumps, as well as the “cold well” pumps. However, we would not be using the existing tower basin because we needed to demolish the old tower sitting on top. All that we could use was the cold well sump in the basin’s corner. h e good news was that we had the means to isolate the cold well sump from the existing basin, thus enabling us to install new piping from the bottom of the new, elevated modular towers discharging down into the existing cold well sump. h is enabled us to switch to the new towers on the l y with minimum downtime. However, the volume of the cold

well was reduced by about 75 percent, which would later prove to be a challenge in balancing the l ows of the three hot well pumps that fed the tower with the two cold well pumps that forwarded the cooled water out to the process units.

When the time i nally came to switch over, our goal was to do so in less than one hour, even though we had planned for eight hours of downtime. At er we valved out the old tower and lined up the new tower, we i red up the hot well pumps. At er allowing about 20 seconds to hydraulically i ll the new towers, and generate sui cient water volume in the cold well sump, we started-up the i rst cold well pump. I will never forget what happened next.

I was standing approximately 30 t from the cold well pumps. Within seconds of starting the cold well pump, a sound similar to a ril e shot was heard and the cold well pump shut down. Before I had time to swear, I saw a tsunami coming over the top of the cold well sump. Fortunately I was still l eet of foot, otherwise I would have taken a bath. We shut of the hot well pumps to stop the water feed to the towers. h e production engineer called on the radio and asked what happened. I did not know. He reminded me that due to the current draw on the motor upon start-up, the manufac-turer recommended no more than three starts within a one hour time span. Otherwise we needed to let the motor cool for at least an hour. To add more pressure, the produc-tion manager called 10 minutes into the outage and asked where the water was. He needed cooling water l ow restored ASAP, even though he had previously agreed to more time.

I was feeling mounting pressure. h e production engineer called again on the radio and said, “h e current overloads on the pump motor tripped. What do you want to do?” Instinct took over and I said “Let’s reset the overloads and try it again.” “Okay,” he said with an air of skepticism. h e overloads were reset, and then we restarted the hot well pumps. At er l ow to the cold well resumed, the cold well pump was started. Unfortunately, it was the same result; the cold well pump immediately shut down with a bang. h e overloads tripped again. I was bal ed, and getting worried.

Although at the time I knew that doing the same thing and expecting dif erent results was insanity, I was caught in the moment with which many struggle—the needs and pressures to produce results overtake that part of our brain that tells us to slow down, stop and think. I was down to my last start of the motor; if it did not work, the plant would be down another hour, which meant signii cant lost proi ts. h is would not bode well for an ambitious young engineer.

Maintenance Minders

h e production engineer walked out of the control room. Looking over the top of his safety glasses, he said, “Now what? h is is your last shot for the next hour.” I knew I could not attempt a third restart without understanding the causes of the tripped motor. “Give me a minute,” I said. I walked away and did what I should have done the i rst time—think about the causes of the tripped motor.

“Why is the motor tripping?” I asked myself. “Because the motor is overloaded,” I thought (see Figure 1).

Next, “Why was the motor overloading—what was causing this?” High current draw had to be the reason. I called the opera-tor to verify in the distributed control system. It was coni rmed (see Figure 2).

“Nothing could be wrong with the pump or electrical system,” I thought. “h e pump was running i ne just one hour prior.” I tried to visualize the pump curve. At er a few seconds, I realized I had completely forgotten centrifugal pump operation basics. “Maximum current draw on a centrifugal pump occurs in high l ow, no head situations.” I was embarrassed for myself. “So, why are we in a no head situation?”

h en it hit me—because the discharge piping for the cold well pump ran underground immediately upon exiting the pump discharge, it partially drained while we were switching over to the new tower. I estimated about 100 t of discharge pipe was likely empty. h is would indeed create a “no backpressure” or “no head” situation upon start-up (see Figure 3).

Now, I felt coni dent I was on the right track. With little time before I had to answer to the production manager, I needed to create backpressure. Sometimes, the answers are staring you in the face if you just stop long enough to see them. “How about that manual valve of the discharge of the cold well pump,” I thought.

I walked up to the production engineer and said, “Let’s close the discharge valve completely, then start the pump. At er a couple seconds, have the operator slowly open the valve.” “What does that have to do with it?” he asked. I replied, “Everything. We need backpressure to move to the let -hand side of the pump

curve to limit the current draw.” His expression, coupled with “Whatever you say!” made it clear he was not buying it, but I was coni dent that I understood the causes of the problem and how to solve it.

At er closing the discharge valve, the cold well pump was started and continued to run smoothly, much to my relief. h e discharge valve was slowly opened, the line rei lled and produc-tion resumed as planned.

I suspect most of you immediately knew the problem and the obvious solution. Yet, I was faced with the “just get things running” mentality coming from people above and below me on the organizational chart and from customers expecting on-time delivery of product. Instinct took over, I initially acted without thinking, and solutions did not seem obvious. At er the fact, I could not believe it took me so long to solve it.

I learned an important lesson that day at the cooling tower: If I resist the temptation to shoot from the hip, call timeout, take a few extra minutes to organize thoughts causally and structure my approach to problem solving, it is the best investment in time I can make. Even in today’s fast-paced and pressured climate, time spent reworking problems is waste from which we can never recover. Using a structured approach to problem solving (like root cause analysis)—even if all you have time to do in the heat of a crisis is work through the process in your head—can be critical to avoiding repeat failures and lost production or proi ts.

Plastic pneumatic diaphragm pumps are used widely in chemical, semiconductor and pharmaceutical applications, as well as other industries that require

sanitary operating atmospheres. h ese pumps are ideal for these applications because of their almost universal chemical resistance—due to housing materials constructed of PTFE (polytetral uoroethylene) and conductive PTFE—and high wear resistance—thanks to housing materials that use PE (polyethylene) and conductive PE.

With the increasing degree of automation found in plant construction and operation, functional reliability is playing an enhanced role with respect to a plant’s total cost. h erefore, it is crucial that the right components contribute to a plant’s operation (for example, comparatively low-cost pumps that are small, but ef ective) as unscheduled plant shutdowns and production downtime quickly result in high costs.

The ChallengeFinding the proper pump for a specii c production process requires a lot of legwork. Dif erent pump modes of operation must be considered—from positive displacement to centrifu-gal to peristaltic—along with workload, l ow rates, working pressures, etc.

One style of pump for chemical, pharmaceutical or semiconductor operations is pneumatic diaphragm pumps. h ese pumps are commonly used in static-l uid energy machines characterized by energy conversion in an enclosed working space with periodic energy transfer. Appropriate to their mode of operation, these pumps are classii ed as lift-displacement machines. Features of pneumatic diaphragm pumps are a gentle product displacement, dry-running and overload-proof operation, self-priming, insensitivity to solids, ini nite variability and easy-to-operate functions.

One key to pump ei ciency is its ability to provide a uniform delivery l ow. To achieve this uniform l ow rate, along with design-related, low-residual pulsation, pneumatic

diaphragm pumps are usually designed as externally circu-lated double-diaphragm pumps (Figure 1). Two identical diaphragms are arranged opposite of each other, with each separating the air chamber from the product chamber, while they are interconnected by means of a piston rod.

h e pressurized “drive air” created by the pump’s opera-tion l ows into the chamber behind a diaphragm. To enable the pump to perform its working stroke, the introduced compressed air must overcome the pump’s internal friction (static/sliding friction on the sealing and bearing elements) and the diverting forces of the diaphragms, as well as the product-sided back pressure. h e continuous l ow of drive air causes the pressure behind the membrane to increase until the counteracting resistance forces are overcome. h e diaphragm then displaces the medium from the decreas-ing product chamber and performs its working stroke. h is forces the transported medium to be pushed out of the pres-sure side. To ensure adequate operation, the diaphragm is pressure balanced during the delivery stroke.

Meanwhile, the opposite diaphragm, which is connected via the piston rod, moves toward the stroke-performing dia-phragm. h e expanded air behind this diaphragm is allowed

Proper air-control systems increase effi ciency and

reliability of pneumatic diaphragm pumps.

Effi ciency Matters

to escape. h e medium then enters the enlarging product chamber on the suction side, allowing the diaphragm to perform its suction stroke.

h e crux of this pneumatic double-diaphragm design dictates that maximum delivery volume and the maximum possible deliv-ery head (i.e., back pressure) are the main parameters of the pump’s operation. h e dimensioning of the necessary wall thickness, product passage cross-sections and valve lift grow out of these design parame-ters. h erefore, the delivery volume of pneumatic diaphragm pumps can be inl uenced via the form and dimensions of the displacement chamber, the volume-changing kinematics (or diaphragm stroke) and the number of working strokes per unit of time.

Additionally, the design of the product chamber and determina-tion of the diaphragm stroke are mainly aimed at achieving a long

diaphragm life. Ideal dimensions are large diaphragm diameters combined with small diaphragm strokes. h e geometrically optimized design of the air or product chamber for the minimization of dead volume in the respective i nal diaphragm position positively inl uences the pump’s ei ciency.

h e number of maximum possible working strokes (in addition to drive and back pressure) depends on the air passage volume to be i lled behind the diaphragms. h e dimensioning of the air passages must be optimized. On one hand, this volume should be minimized to avoid unnecessary dead volume. On the other hand, the air passage cross-sections within the pump and the air-control system must be dimen-sioned for the expanded, pressure-less air, as this takes up a larger volume than the pressurized drive air. h e expanded air behind the diaphragm performing the suc-tion stroke must be able to escape quickly enough to prevent the entire system from slowing down by an inei cient “air cushion.”

Because of the pump’s designed-in internal l ow reversal, pneumatic diaphragm styles require a control that provides the diaphragms with an alternating supply of compressed air. In modern combustion engines, injection systems distribute the fuel/air mixture to the individual cylinders. Air-control systems in pneumatic dia-phragm pumps alternately introduce pressurized air into the air chambers behind the diaphragms or discharge the expanded air to the silencer.

h e two types of air-control systems are direct and indirect. Direct air-control systems are characterized by how the distance of the control travel by the pilot piston corresponds to the diaphragm stroke. Direct air-control systems are normally used in small sizes (piston rod=pilot piston) and are arranged centrally between the diaphragms.

With indirect air-control systems, by contrast, the travel distance of the pilot piston does not correspond to the diaphragm stroke. h e pilot piston is controlled only during the last millimeters of the diaphragm stroke. h e air-control system is

also arranged between the diaphragms, and the piston rod and pilot piston are two entirely dif erent components (Figure 2).

The Solution

Air-control systems operate under extreme conditions. h ey switch up to 10 cycles per second, are subject to pressure dif er-ences up to 7 bar, come into contact with chemically aggressive atmospheres depending on the pump application, and must be reliable and maintenance-free for the above reasons.

h ese requirements are met only by precision controls, such as pneumatically piloted air-control systems.

To achieve high-reversing frequencies, a pneumatically piloted air-control system makes use of two compressed air properties, high l ow rates and small mass.

h e pneumatically piloted air-con-trol system has only two moving com-ponents (the main and pilot pistons), is a 5/2 way valve (Figure 3) and consists of four dif erent, completely metal-free components (Figure 4). h e pilot piston controlled by the diaphragm opens and closes via control edges. Air passages below the main piston alter-nately apply compressed air to the left or right side downstream of the main piston. h is pneumatically switches in a horizontal direction, alternately sup-plying the diaphragms with compressed air or discharging the expanded air.

h e position of the pilot piston control edges with respect to the piston rings in the main piston is geometri-cally designed, so the air control is always clearly dei ned and independent of the position of the main piston and

pilot piston with respect to each other (during pump operation or after unit shutdown).

h e air-control system is without dead center and fuli lls the most important criterion relating to an air-control system for pneumatic diaphragm pumps.

In the case of internally circulated pneumatic diaphragm pumps (which have been specially developed for the semi-conductor industry), the air-control system is not arranged between, but next to, the diaphragms. h e result of this design is a minimal number of surfaces in contact. h is eccentric arrangement of the air-control system was previously directly operated within older pumping units.

h is is where newly developed, pneumatically piloted air-control systems with built-in drag systems come into play

(Figure 5). h e pilot piston is decou-pled from the full diaphragm stroke and, like an indirect air-control system, is initially carried along toward the end of the diaphragm stroke. h e main piston control’s travel distance, which depends on the pilot piston travel, decreases. h e advantage is an optimi-zation of the air-sided dead volume, as less volume is i lled with compressed air and less expanded air must be dis-charged to the silencer.

In contrast to other air-control sys-tems with vertically arranged main pis-tons, the position of the main piston of this air-control system is always clearly dei ned after pump stoppage from any operating point, as the main piston does not need to fall back into an “ini-tial position” by gravity (which makes them susceptible to faults as the main piston can stick in this arrangement

Figure 3 Figure 4

Figure 5


and not reach its necessary initial position).h e control-valve housing, the two caps and the main

and pilot pistons are made of PETP (polyethyleneterephtha-late). PETP is a plastic with high strength, rigidity, form and dimensional stability. PETP is also characterized by favorable sliding and wear properties. Because of PETP’s good machin-ability, the narrow tolerances necessary for sealing purposes can be adjusted with the associated surface quality.

Sealing of the air passages between the main and pilot pis-tons occurs with the aid of piston rings. Because sealing points at components that move relative to each other are always sub-ject to friction, the static and sliding friction coei cients are minimized, and wear behavior is positively inl uenced. h is is also an optimization process.

On the one hand, the piston rings must be capable of exert-ing sui cient sealing force to prevent leakages. On the other hand, the sealing force must not be excessive, as this would increase the internal friction, which expresses itself in unneces-sary wear and heat development.

h e air-control system is provided with piston rings of a PTFE compound. PTFE is characterized, in addition to its almost universal chemical resistance, by excellent sliding prop-erties (μ=0.05...0.25) and temperature resistance up to 260 deg C (500 deg F). h is admixture gives the PTFE parent material the necessary wear resistance for these applications.

Conclusion

High demands are placed on pneumatic diaphragm pumps, as pump failures in an age of automation in plant construction are often accompanied by undesired production downtimes that can incur enormous costs. h ese requirements apply in particu-lar to air-control systems of pneumatic diaphragm pumps.

h e pneumatically piloted air-control system is a precision control system, which is based on the geometric design of the pilot piston control edges and the associated piston ring seals on the main piston, which is absolutely without dead center. Independent of the position of the main and pilot pistons with respect to each other, the air passage cross-sections for rever-sal of the main piston at all operating points of the pump are always clearly dei ned.

Material selection enables maintenance-free operation, as this air-control system operates without lubrication.

The term carbon footprint has become synonymous with greenhouse gas (GHG) emissions and climate change. Carbon footprint commonly refers to the

volume of greenhouse gases, the most prominent of which is carbon dioxide, which are emitted by an organization, event, process or product.

Because of climate change concerns, coupled with rising energy costs and dependency on non-renewable and foreign sources of energy, the related term energy footprint is enter-ing the vernacular of industry and regulatory organizations. h e U.S. Department of Energy (DOE) developed energy footprints to help target energy saving opportunities in the manufacturing industry. h ey map the l ow of energy supply and demand in facilities and show where and how the energy was used and lost from inei ciencies. h e DOE uses energy footprint maps such as the one in Figure 1 to track the l ow of energy supply, demand and losses.

Pumping SystemsWith the growing focus on the energy footprints of industrial facili-ties, pumping systems have received signii cant attention. DOE data indi-cate that pumping systems consume almost 20 percent of the world’s elec-trical energy demand. To help pump users address this issue, the ASME recently published Standard EA-2-2009, Energy Assessment for Pumping Systems. h e Hydraulic Institute (HI) has also focused attention on energy improvements with the Pump Systems Matter educational initiative.

Sealing SystemsSealing systems are often neglected as contributors to the pump system energy footprint. For most applications, a well engineered sealing system can provide reliable, low emission performance with an insignii cant energy footprint compared with the overall pumping system. However, poor selection and implementation of the seal coni guration and associated seal support systems can result in an energy footprint that approaches, or in some cases exceeds, that of the pump.

h is is the i rst in a series of four Sealing Sense articles designed to explain how the selection and application of sealing systems af ect their energy footprint. h e series will provide guidance on best practices to minimize the sealing system’s energy footprint size.

What Is The Energy Footprint of Sealing Systems?

SEALING SENSE


h is i rst article provides an overview of the sealing system energy footprint and the energy losses from the interaction between the mating seal faces. h e September article will focus on the impact of thermal inputs to maintain the l uid tem-peratures for high-temperature processes. h e October issue will address the energy impact of removing diluents introduced as seal l ush l uids from the process stream. h e i nal install-ment will cover the impact of pump shutdown, repair and re-commissioning on sealing system reliability and the energy footprint.

Seal Face Interaction

Mechanical seals operate with one of three mating face lubrica-tion regimes. h ey are boundary lubricated, full l uid i lm and mixed lubrication.

Boundary LubricatedFor seal faces operating in this mode, the mechanical load is transmitted almost entirely by contact of the asperities on the surfaces of the rotating and stationary seal rings. h is contact consumes electrical energy from the pump driver and converts it into thermal energy from friction between the mating sealing surfaces. h e amount of power “lost” at the seal faces is calcu-lated by the formula:

Q (in Watts) = π(ro2 – ri

2)[po(B-½)+ps]Vƒc

Where:ro = Seal face outer radius (m)ri = Seal face inner radius (m)po = Pressure at the seal face outer radius (Pa) ps = Pressure on the seal faces from the spring forces (Pa)B = Seal balance ratioV = Sliding speed at the mean radius of the seal faces

(m/s)ƒc = Friction coei cient between the seal faces

Figure 2. Seal face lubrication regimes

Sealing Sense is produced by the Fluid Sealing Association as part of our com-mitment to industry consensus technical education for pump users, contrac-tors, distributors, OEMs and reps. As a source of technical information on sealing systems and devices, and in cooperation with the European Sealing Association, the FSA also supports the development of harmonized standards in all areas of l uid sealing technology. h e education is provided in the public interest to enable a balanced assessment of the most ef ective solutions to pump systems technology issues on rational Total Life Cycle Cost (LCC) principles.

h e Mechanical Seal Division of the FSA is one of six with a specii c product technology focus. As part of their educational mission they develop publications such as the Mechanical Seal Handbook, a primer intended to complement the more detailed manufacturer’s documents produced by the member companies. h is document served as the basis for joint development of the more comprehensive Hydraulic Institute publication: Mechanical Seals for Pumps: Application Guidelines. Joint FSA/ESA publications such as the Seal Forum, a series of case studies in pump performance, are another example as is the Life Cycle Cost Estimator, a web-based software tool for determination of pump seal total Life Cycle Costs. h e Sealing Systems Matter initiative was also launched to support the case for choosing mechanical seals that optimize life cycle cost, energy usage, reliability, safety and environmental compliance.

h e seal balance ratio represents the portion of the hydraulic pressure from the l uid sealed that provides a force pushing the seal faces closed. h e simplest seal designs are unbalanced but can result in thermal energy generation more than two times that of a balanced seal. For a typical single balanced rei nery seal operating at 3,600 rpm and 20 bar (300 psi) on a 50 mm (2 in.) shaft size, the thermal power per this formula is 970 W (3,300 Btu/hour).

Full Fluid Film Lubrication

h is regime occurs when the mating seal faces are separated by a thin i lm of l uid, and no physical contact exists between the sealing surfaces. Hydrodynamic seal face topography can be used to create the sep-aration forces that enable a seal to operate in a full l uid i lm mode. For liquid lubricated seals, the associ-ated energy losses from viscous shear can still be noteworthy, especially when the l uid between the seal faces has a higher vis-cosity. Operation in this regime will also result in higher leakage levels that must be considered for each application.

For gas lubricated dual seals (where an inert gas barrier [typically nitrogen] provides the l uid between the seal faces), leakage of the barrier gas into the process stream and the atmo-sphere is usually well tolerated. Because of the low viscosity of gases, the thermal energy generated by viscous shear of the gas between the seal faces is almost negligible. Figure 3 shows the signii cant dif erences between the power consumption of full l uid i lm gas lubricated and mixed lubrication oil lubricated dual seals.

Mixed Lubrication

h is regime is similar to boundary lubricated, but the l uid in the gap between the seal faces supports a portion of the con-tact forces between the seal faces. h e thermal energy generated from contact friction between the seal faces is decreased with mixed lubrication, but the additional source of thermal energy from viscous shear of the l uid i lm between the seal faces becomes more signii cant. h e magnitude of the viscous shear thermal energy increases in direct proportion to the viscosity of the l uid between the seal faces. For dual seal applications, where the barrier l uid provides the lubrication between the seal faces, lower viscosity barrier l uid can signii cantly impact the sealing system energy footprint.

Auxiliary Systemsh e seal face thermal energy footprint is further magnii ed when auxiliary piping systems with heat exchangers are required to remove the thermal energy generated at the seal faces. h e heat

exchangers often require circulation of cooling water and oper-ation of cooling towers or similar devices to recycle the cooling water. Dual gas seals have the advantage of not requiring any kind of cooling equipment to remove thermal energy since low levels of heat are generated at the seal faces.

Conclusionh e energy footprint from the interaction of the mating seal faces can be minimized by the following:1. Always employing balanced seal designs2. Selecting a barrier l uid with the lowest viscosity for the

application3. Using seal designs operating in a full l uid i lm mode when

appropriate4. Applying gas lubricated dual seals when application condi-

tions allow

h ese basic seal system considerations can signii cantly reduce the energy footprint of the seal face interaction. h eir contribution to the overall sealing system energy footprint should be considered after review of all the components of the sealing system’s energy footprint. h e next Sealing Sense articles will focus on considerations related to coni guration, opera-tion and maintenance of the sealing system, which can greatly impact the energy footprint.

Q. What is the preferred method for starting reciprocating power pumps?

A. Starting a reciprocating pump with a closed discharge valve is naturally dii cult due to the high torque required to over-come discharge pressure as well as accelerate the pump. For this reason, reciprocating pumps are typically started with an open bypass line from the discharge to the suction.

To accomplish this, the operator manually opens a bypass valve, or a power-actuated dump valve is programmed to open automatically, which bypasses the liquid during the start and stop functions.

A check valve is employed in the pump discharge line. It remains shut as long as the bypass (dump) valve remains fully or partly open (see Figure 6.47).

h e liquid pressure exerted on the plungers (or pistons) is largely caused by liquid mass and friction as it passes through the bypass valve and piping.

When correctly sized, the bypass valve and piping cause low back-pressure. Only a relatively small torque is required while bypassing the liquid to a tank.

With liquid bypass, the total starting torque requirement is mainly related to the mechanical inertia of the pump, cou-plings, gears and motor rotor. h ese components are heavy, and substantial starting torque may be required. All the liquid in the pump suction line and bypass line must be accelerated from standstill to full liquid velocities.

h e torque needed to accelerate the entire mechani-cal hydraulic inertia system depends on the inertia of all the moving parts, including the liquid, the rate of acceleration and the total system friction.

Some pumps are provided with mechanical suction valve unloader devices. h ese devices reduce the total starting torque requirement to that needed to accelerate the mechanical items, such as pump crankshaft, gears, couplings, etc. h ey stop liquid pumping action by mechanically holding open the pump’s suc-tion valves, allowing the liquid inducted into each liquid cylin-der to be delivered back into the pump suction.

Because no liquid pumping occurs, the driving machinery does not need to provide any torque to accelerate the liquid. Only the torque to overcome mechanical inertia and friction is needed during start-up. After the pump and driver have reached full speed, the suction valve unloading devices are retracted, and normal pumping action then commences. At this point, the driver must supply additional torque to accelerate the liquid system and also meet the total running torque requirement caused by discharge pressure.

More information on reciprocating pumps can be found in ANSI/HI 6.1-6.5 Reciprocating Power Pumps for Nomenclature, Dei nitions, Application and Operation.

Q. What is critical speed when referred to a pump?

A. Critical speed is one or more speed values that coincide with a natural frequency of vibration of the pump rotor or structure. A resonant condition can result when the operating speed or vane-pass frequency of the pump excites the structure’s natural frequency. At resonance, the vibration levels will be amplii ed depending on the amount of damping present in the system.

Much attention is often given to the value of the natural frequency of the pump assembly. However, in a i eld instal-lation, the structure comprises—in addition to the pump—the foundation, the mounting, the piping and its supports, and may include the driver and coupling or driveshaft(s), as applicable. h e natural frequency of the total structure may, therefore, dif er signii cantly from the natural frequency of the pump alone.

h e system designer should consider this to ensure an

appropriate separation margin exists between the system’s natu-ral frequency and the operating speed. For systems that oper-ate over a speed range, natural frequencies may fall within the operating range and critical speeds may be identii ed. In such cases, due care and consideration must be taken to evaluate the possibilities of avoiding such operating speeds or mitigat-ing the possible ef ects on bearing housing (or other) structural resonances.

See HI Standard ANSI/HI 9.6.4 Rotodynamic Pumps for Vibration Measurements and Allowable Values for more details.

Q. Why are some rotary pumps built with timing gears and others are not?

A. Timing gears are intended to synchronize the rotation of two separate rotors in pumps that use screws, gears, lobes or similar devices to move liquid through the pump. See Figure 3.16. h e timing gears can be seen on the right hand end of the rotors.

Some rotary pumps, such as sliding vane pumps, have a single rotor, and synchronizing two rotors is meaningless. Some two-rotor pumps, such as gear pumps, rely on the driven rotor to drive the second rotor, and timing gears are not used. However, when pumping abrasive liquids, the addition of timing gears will relieve the pressure between the meshing gear teeth in the pump and reduce wear. In this case, the timing gears are moved out of the pumping chamber and sealed against leakage along the rotor shaft.

Lobe pumps and some screw pumps cannot drive the second rotor from the i rst rotor, and timing gears are then necessary.

More detail on rotary pumps can be found in ANSI/HI 3.1-3.5 Rotary Pumps for Nomenclature, Dei nitions, Application and Operation.

Back to Basics

Frequency analysis is an important method of vibration analysis. It provides information on vibration sources and helps identify those components in the vibration

signal that are often small, but nevertheless important, for diagnosis. Each vibration can be attributed to a particular excitation source or machine part.

Irregularities or damage lead to changes in the frequency spectra’s appearance. h ese faults include mechanical or ther-mal unbalances, characteristic vibrations, changes in align-ment, defective bearings, gear tooth damage, changes in play, frictional corrosion, tears, etc.

Digital FFT analyzers are state of the art. Fast Fourier Transformation (FFT) is a mathematical procedure that automatically occurs within the measuring device and pro-duces frequency spectra.

FFT analyzers display spectra as line graphs. To achieve a high frequency resolution, the number of lines (LOR) should be as high as possible. While the minimum number of lines required is 800, it is preferable to have more. Of course, time to collect the spectra will need to be considered since the higher amount of time to collect data is equal to the higher number of lines of data that are collected. For most stan-dard operating machines, 1,600 LOR is normally used for adequate data collection and for faster data collection.

h e amplitudes of the individual frequencies are dis-played during measurement. h ey can be plotted on a linear or logarithmic scale for each component of the spectrum. h e linear display shows magnitude only. h e logarithmic display, on the other hand, shows even the smallest vibra-tions. h e prerequisite is that the frequency analyzer have an amplitude resolution of at least 100 dB.

Likewise, the frequency scale can also be either linear or

logarithmic. It should be noted that it is virtually impossible to compare frequency diagrams plotted on a dif erent scale even if they contain the same information. We recommend a linear scale for displaying amplitude and frequency.

How to Measure Valid Frequency

SpectraWhen dealing with FFT spectra, there is a danger of incor-rect measurements that can result in diagnostic errors. In fact, almost all suppliers of frequency analyzers of er special train-ing courses and thick manuals. h is still does not prevent false measurements from occurring frequently—particularly in the case of gear analyses—as a result of insui cient mea-surement technology. Pay attention to the following settings while taking measurements.

Adequate Measurement PeriodsAn ef ective measurement period is decisive in the analysis of vibration signals. If loads change, e.g. as in wind powered systems as a result of wind gusts, measurement periods of up to i ve minutes may be required for reproducible mea-surements. For constant speed rotors and RPMs greater than 200 rpm, we recommend an ef ective measurement period of at least 10 seconds and, at RPMs greater than 20 rpm, a measurement period of at least 60 seconds. A measurement period of 60 seconds at 20 rpm means 20 revolutions are the basis for the technical estimation of the rotating shaft vibration. Since few analyzers allow the measurement period for measurements within the frequency range to be adjusted directly, the number of averaging must be set high until the measurement periods given above are reached.

Basic Rules for Measuring Frequency SpectraMickey Harp, Ludeca, Inc.

The measurement settings to consider while

measuring valid frequency spectra.


High Enough Frequency Ranges h e requirement for long mea-surement periods and high fre-quency ranges places the high-est demands on the frequency analyzer. For example, if two channel vibrations up to 2,000 Hz are recorded for i ve min-utes, 1 MB of measurement data is collected to be processed. Usually, the upper limits of the frequency range under consid-eration have to be greater than the number of revolutions by a factor of approximately 100. Alternatively, the frequency range can be broken down into several sections and carried out in several measurements, but this takes time.

Recommended Frequency Resolutionh e analysis of sidebands is an important tool in machine diag-nosis. For the sidebands to be adequately resolved, the number of lines must be correspondingly high. h us, a frequency reso-lution of 1,600 lines is recommended for standard machines, and 8,200 lines for multiple stage high-performance gears. Alternatively, the frequency range under analysis can be dis-sected into several small sections again and perform several measurements with a smaller line count. However, the time required increases considerably.

Suffi ciently High Amplitude ResolutionIf individual frequency components are lost in the noise pro-duced by the measurement technology, the measurement technician misses information. On cooling tower drives, for example, strong winds can cause vibrations of up to 15 mm/s, while the actual gear vibrations in the i nal gear drive stage are 0.015 mm/s, i.e. 60 dB weaker. h erefore, the measuring system should have a signii cantly higher dynamic response (e.g., 100 dB amplitude resolution). Alternatively, the user can attempt to i nd ranges where the interference vibrations do not occur so strongly or where the specii c gear vibrations are higher by using more measurement locations, but this also increases the measurement overhead.

Correct Window FunctionHarmonic and square-wave vibrations must be evaluated dif-ferently in FFT frequency analysis. Information is lost if the correct window functions for the FFT algorithm are not used. Digital i lters can be better adapted to the specii cs and give better results. We recommend using a Hanning i lter as the window function and not to change this as far as possible.

Pump Business Special Report

Distributors play a vital role in keeping the lines between manufacturers and users operating smoothly. h ey can expedite response times,

enhance a company’s reach and even create value-added packages.

“Distribution is the single most viable alternative to complement and supplement a direct sales organization,” says Phillip L. Peck, director of sales for EagleBurgmann, U.S. Even the most ei cient companies will i nd it virtually impossible to be all things to all people at all times. A strong distributor network can help make that scenario viable.

Manufacturers should rec-ognize and treat distributors as an integral part of their teams. “Distribution plays a unique role in that they are both a business partner and a customer at the same time,” says Peck. Manufacturers should look at distributors as they would their best customers—build relationships with them and take the time to educate them about the product.

Peck adds that most distributors are looking for “manu-facturers that view them in a positive light and support them with marketing tools and strategies to ensure they are com-petitive in their markets.” Manufacturers who take care of their distributors will i nd that their distributors take care of them.

The Role of DistributorsGiven the size and scope of the U.S. economy, distributors have long been relied upon to serve as a bridge between man-ufacturers and customers. In today’s increasingly globalized

marketplace, this link becomes even more important. Today, wholesale distributors make up an estimated 5.75 percent of the gross domestic product in the U.S. and Canada, and employ 3.3 million workers.

One of the most resounding arguments for a solid dis-tributor network is the speed with which manufacturers can respond to customer demands. It is crucial today to be able to respond to customers quickly and in real time. Because they are more localized and nimble, distributors can typically of er a faster response. “To truly be customer-driven, manufactur-

ers need to adjust their businesses to meet the needs of the customer, which in today’s marketplace means local service, local inven-tory and technical sales people,” says Skip Giessing, a division vice president for DXP Enterprises, an industrial distributor.

A network of distributors often has a greater ability to of er face-to-face service. “Good, solid geographic and account cover-age is crucial to success no matter what the economic conditions,”

Marty Gass, regional manager for EagleBurgmann, says. With distributors in key geographic areas, manufacturers can service customers on a level that would be dii cult or even impossible for a main-oi ce sales force.

h ere is also networking potential. Because they often represent several companies, distributors can have access to new accounts for the manufacturer’s sales force.

Distributors do not only of er benei ts to manufactur-ers—they can also be a boon for users. Because distributors represent multiple products and companies, they can bundle. If they are selling the pump, the coupling and the mechanical seal, they can provide a system. h e user’s buying process is

Distributors can help an organization be

profi table and deliver value to the marketplace.

Five Questions to Build

Distributor Relationships

To build relationships with their distributors, manufacturers should start by asking them-selves these i ve questions:

Who are our distributors?• Why are they here?• What can they do for me?• What should I do for them?• How can I get them to sell my products?•


streamlined, and costs are often lowered, as well.Distributors also have the benei t of reducing

inventory and service burdens for both the manu-facturer and the user. h is is especially crucial now, when many users have been forced to cut back on in-house inventories and service staf . “Distributors, now more than ever before, are service providers,” says Giessing. “h ey do not just provide products. h ey provide aftermarket services, cost reduction and process optimization strategies, as well as inven-tory management. Distributors create value by pro-viding total solutions for their customers.”

Working with DistributorsInstead of simply handing of C- and D-level accounts to distributors, manufacturers should treat them as an equal part of the sales force. Manufacturers should build open relationships, and make distribu-tors part of the team. “View the distributor as your own mini sales organization, which needs your time on a regular and con-sistent schedule,” advises Peck.

Distributors also need to be knowledgeable about the manufacturer’s product to sell it. Because they are not employed by the manufacturer and also represent many other products, this knowledge is not innate. Manufacturers should take time to teach them about the product. “h ink of how you would deliver a presentation at a sales meeting and be like that all the time with distributors,” advises Gass. “Be excited about your product and excited about their opportunities.”

If the manufacturer criticizes the distributor for not work-ing hard enough to sell its products, it should ask if it is sup-porting the distributor appropriately. Is the manufacturer easy to do business with, and does it of er the distributor oppor-tunities to make money? “Complicated pricing and discount-ing policies, cumbersome order entry procedures, and slow or non-responsive organizations will i nd it dii cult to grow their

business through distribution,” says Peck. When the manufacturer is a new item on a distributor’s

line card, it should ask the distributor how it can move up. h e manufacturer needs to discover what the distributor needs. Without a sales and technical staf to support the distributors, manufacturers must have materials and resources needed by distributors easily accessible online.

More often in this industry, specialized, small-scale dis-tributors are needed. During the last decade, many plants and mills have consolidated and reduced the number of suppliers. In many cases, the industry now turns to distributors to provide these services.

Specialized distributors are a good i t in this capacity, as they have the knowledge to deal with issues like specifying or taking a size i tting. “It is a common misconception that we just take orders and stock shelves,” says Mark Pettibon, sales manager for EWProcess, “but our people have a lot of technical expertise. We can provide engineered solutions for tough, complex situations using the best available technologies.” Couple this trend with the reality that many plants have lost some of their technical staf , and an experienced, knowledgeable distributor goes from an asset to a necessity.

“h e idea that distributors are just middlemen overlooks the true value that distribution of ers,” says Pettibon. “We are so close to the customers that we can actually help drive sales, not just deliver the product. We are able to solve problems, as well as identify market trends and pass this information

back to the manufacturer. In many ways, we are their eyes and ears to the industry and their customers.”

Aftermarket

It is often said that a picture is worth a thousand words. h is old adage could not have been truer when a coal-i red power station received pictures from the inspection team at a service

center. h e plant had pulled a previously rebuilt Worthington boiler feed pump from storage and sent it to the service center for disassembly, inspection and reverse engineering. What the inspec-tion team found was a number of repair defects uncovered from the previous repair process.

Because many repaired pumps initially go into storage as this one did, the consequences of a poorly rebuilt pump may not be revealed until several years later. h e unfortunate results can range from reduced pump ei ciency and shorter mean time between repair to catastrophic failure and unplanned outage. In this par-ticular case, the repaired pump had been in storage and not been run since the repair was completed. It was therefore in its “as built” condition when it arrived at the service center. h e photographs that follow illustrate a number of the defects that were uncovered and how they af ect the performance and reliability of the pump.

Moreover, the suction vane edges were ground l at, which results in a loss of performance and NPSH. As much as i ve to seven additional feet of NPSH required by poor prac-tices could result in cavitation and reduced operating life.

While any repair provider can make a mistake or be guilty of an oversight, the almost systemic lack of quality and poor workmanship from this previous repair provider was surprising. h e lesson learned from this discovery of a poor pump repair is that pump users must be involved in qualifying their service providers, obtaining a thorough understanding of that provid-er’s capabilities and ensuring measures have been implemented to achieve quality standards.

Practice & Operations

A green product means dif er-ent things to dif erent people. For some, a green product is

alternatively powered, such as some of the recently introduced solar-powered well pumps. For others, green refers to products made from sustainable materials. In this article, green means a pump or pump system that uses less energy or reduces material usage through its design.

Pumps are often considered the second most common machine in the world after the electric motor. Billions are running in the world, bringing drinking water; disposing of waste; and working in cars, buses, planes, power plants, process facilities, cool-ing systems, etc. With all these pumps running in the world, even a relatively small increase in ei ciency could result in a huge reduction in energy consumption.

Energy reduction in pumps and pump systems can come from several areas. Most pump professionals would agree that the biggest potential energy reduction opportunities lie in the proper application and control of pumps with respect to the system demand. Simply, this means properly selecting and controlling the correct pump for the application. Many end users probably believe that their pumps run close to their best ei ciency. In a relatively famous study, “Expert Systems for Diagnosis and Performance of Centrifugal Pumps,” the Finnish Technical Research Center (www.vtt.i ) found that the average pump operates at less than 40 percent ei ciency

in the i eld, and 10 percent of pumps operate at less than 10 percent ei ciency. h e solution to many of these ei ciency problems is not selecting a new, higher ei ciency pump or motor, but analyzing the pump system to ensure that the pump is properly sized for the application.

Several free, online system calculation tools allow even a novice user to input the components of his system with pipe sizes and generate a system curve showing the expected losses from the pump system. One such tool, Pump-Flo (www.pumpl o.com) from Engineered Software, allows the user to develop a system curve and then select from 85 dif erent man-ufacturers to i nd a pump that matches the requirements.

What about pump manufacturers? If the majority of the potential energy savings lies with the pump’s proper application, is room left to improve the products from the

manufacturer’s point of view? I routinely i nd clients with many underperforming pumps in their portfolios. h ese pumps are far below the ei ciency of the competi-tive pumps in the marketplace. Modern hydraulic design tools can help the design engineers create and analyze pumps that can compete in the global market with higher ei ciencies, lower Net Positive Suction Head Required (NPSHR) and better reliability.

Modern mechanical design tools allow the calculation of stress levels in compli-cated shapes and allow the designer to remove excess metal in lower stress regions while maintaining the needed structural strength in others. h is leads to less mate-rial usage, lighter components and less-expensive component costs. By combining these two initiatives, many pump companies can use these new tools to lower costs while providing a greener, more competitive product.

Modeling the Impellerh e impeller is the only element in the pump that adds energy to the liquid. Maximizing the amount of energy transferred into the liquid is the most crucial step in the improvement of a pump’s performance and its ei ciency. Traditionally, design-ers would manipulate the inlet and outlet widths and radii to achieve reasonable velocities and vane angles at the inlets and outlets of each pump component. Once the inlet and outlet angles were determined, the shape of the blading in-between was often determined more by art than science. Some designers used a linear angle change from inlet to outlet; others shaped the vane based on a logarithmic spiral. While these techniques produced many good pumps with excellent performance and

high ei ciencies, in too many others the lab results often fell short of expectations. h is design technique relies heavily on the designer’s feel and experience. If the designer was too aggressive with the change in angle, the impeller would end up with short vanes that were often incapable of guiding the l uid or imparting the required amount of energy. A less aggressive designer might change the vane angle at a lower rate, resulting in a long vane passage that increased the friction and reduced performance and ei ciency.

With the new design tools available today, we no longer have to stumble blindly through the design to determine a pump’s proper blade proi le. h e ability to see into the vane passageways of a spinning impeller and predict the path, veloci-ties and pressure of the l uid moving through them provides an enormous opportunity for product improvement. Looking into the vane passages can be done by using a couple techniques. h e i rst is through the use of streamline curvature calculations to predict the properties of the l ow along discrete streamlines

through the pump. Using multiple stream-lines throughout the passage, the designer can estimate the velocities along the blade surfaces at multiple locations and produce an accurate proi le of the l ow properties. h is provides feedback on blade loading, blade incidence angles and areas of possible stall or separation. h e best part is that the feedback is nearly instantaneous, gener-ally less than a few seconds of calculation time, allowing the designer to try multiple tweaks to improve blade loading, incidence and overall stage performance in a short amount of time.

When the stage appears to the design-er’s liking, the next step is to run the stage through a Computational Fluid Dynamic (CFD) analysis. Since we cannot implicitly

solve the l ow path as a continuous domain, this technique breaks the passageway down into a mesh of small blocks that a computer can solve iteratively. By solving all the l ow equa-tions at each node point, we get a detailed prediction of the velocities, pressures and temperatures at each block. h is allows the designer to verify the performance predicted by the initial meanline design or possibly show areas that could be improved before another CFD run.

CFD comes in many forms. Some codes are general pur-pose and use random, unstructured meshes. h ese meshes gen-erally use the size of a feature to create the mesh around it, so short lines create high mesh densities, often in areas that are unimportant to the l uid’s actual l ow. h ese general purpose tools work well for stationary elements of the pump but often struggle to deal with the interface between moving and non-moving parts. h ey also often require the entire pump to be modeled, resulting in enormous mesh sizes that take a consider-able amount of time to run. Several codes have modules built specii cally for turbomachinery analysis, and most of these use a structured mesh that allows the designer to solve only one blade passage of the pump. h is drastically reduces the number of elements needed for the model, so more elements can be placed in areas of interest, and run times are much shorter. h e results are often more accurate.

Beyond the impeller, CFD can be used to make drastic improvements in the stationary passages within the pump. Complex inlets for pumps, such as vertical in-lines or double suction horizontal split case pumps, are extremely dii cult to design without signii cant testing or the use of CFD. Many of these designs distort the l ow into the impeller so much that they cause major reliability and ei ciency problems, especially at of -design operating points. On one client design a few years ago, we redesigned the inlet of a vertical inline pump and improved the overall ei ciency by 12 percent. h e same logic applies to the pump’s discharge side. I recently changed the volute tongue angle and exit bend radii on a top, centerline discharge pump

design and improved the ei ciency of the unit by three percent.

On the mechanical side of the design, some of these pump design packages have tools to help the designer evaluate the strength and rotordynamic properties of the stage. Tools such as i nite element analysis (FEA) have opened a new world in structural analysis. h ese tools allow for the rapid determination of stress levels, thermal growth and natural frequencies of pump components and the entire stage.

Some of the top-of-the-line packages have mechanical analysis tools built into the software. Tools such as Campbell plots, Goodman diagrams and pre-FEA process-ing tools allow the designer to initially look at the pump’s stress levels and vibra-tory modes without the time and expense

of running a full 3-D i nite element analysis on the stage. h ese tools—the streamline curvature tool for hydraulic develop-ment is one example—allow the designer to quickly try and analyze many dif erent design options before the stage is passed on to a full 3-D FEA, which may take longer to complete. Additional tools such as FEA preprocessing and precondition-ing also accelerate the creation of the FEA model. h e ability to automatically map the CFD-predicted pressure forces onto the pump’s surfaces can save hours of time in developing pres-sure distributions within the FEA software. h e ability to add features such as i llets and balance holes while still in the design package also speeds the development of solid models, as well as FEA model set-up time. Using a combination of the tools men-tioned above, the author has reduced the material weight in several pump designs by 30 – 50 percent, allowing for a major reduction in material usage and overall product cost.

h ese modern analysis tools give pump and system design-ers the opportunity to greatly improve the ei ciencies of their pumps and the performance of overall systems. Even a small increase in the overall ei ciency of these units would mean a drastic reduction in energy usage and lower pumping costs for the end user.
