Morton Grove, Ill. — Jan. 21, 2015 — Xylem Inc.’s Saajhi Stepping Pump received a 2014 GOOD DESIGN award in the humanitarian category for its contributions to the smallholder farmer in developing nations. The GOOD DESIGN program recognizes new consumer products from around the world in 25 categories for design and innovation. The awards receive several thousand entries from companies in 47 countries.

Developed in 2013 through Xylem’s Essence of Life initiative, the Saajhi pump uses human weight and motion to move water. It was designed to help smallholder farmers in rural areas to irrigate their land more efficiently.

“To be recognized by the international design community is a high honor and speaks greatly to the research and development capabilities of the entire Xylem team,” said Keith Teichmann, director of innovative networks and marketing, Xylem. “By striving to deliver the most innovative products for our customers — in developed or emerging markets — our company is changing the way people look at the transport, treatment, testing and efficient use of water.”

The Saajhi pump is part of the Essence of Life initiative, which works with citizens and public and private partners to understand the needs of, and develop solutions for, rural farmers in developing nations. The pump aids farmers in cultivating crops for sale, improving their economic standing within their communities and supporting sustainable rural enterprise. The Saajhi has already improved production for rural farmers, tripling crop yield over rain-fed fields and reducing labor by more than 25 percent over traditional furrow irrigation.

The GOOD DESIGN awards were established in 1950 to recognize the best in contemporary design and have included products from the paperclip to a NASA spaceship. The awards are presented by The Chicago Athenaeum Museum of Architecture and Design in cooperation with the European Centre for Architecture, Art, Design and Urban Studies. Products in the GOOD DESIGN contest are judged for quality design in terms of innovation, new technologies, form, materials, construction, concept, function, utility, and energy efficiency and sensitivity to the environment.

Help! I can’t take apart my Watchman pump.

Volume 2 / Issue 2 / February 2015

You’re ready to disassemble the Watchman pump and motor for servicing when you notice that the instructions say to loosen the fasteners—but the parts list refers to capscrews. Now what?

First, note that we use “fastener” to cover all the possibilities. Current assemblies use capscrews, but versions from 1982 through early 1984 sometimes use studs and nuts. You have to remove the nuts from the bottom of the volute to lift away the motor and studs.

Start by loosening the nuts or capscrews after you isolate the Watchman unit from the system at both the pump discharge and the inlet to receiver. Drain the receiver as much as possible. The static height of any residual water can create pressure that forces the water out of the pump. Loosening the fasteners first relieves this static water column pressure and helps prevent injury or damage from residual hot water.

Second, be sure you know the vintage of your Watchman. That can help you determine what to do if you’re having difficulty lifting the motor and impeller out of the pump volute.

The original 1982 pump used a seal holder and wire spacer, shown in the upper pictures. Note that the wire spacer’s ear protrudes through a slot in the volute, providing a weep path to help customers see that the seal had failed in time to prevent motor damage.

Since 2001, the design has used the DP1966 seal holder with integral spacer, shown in the lower pictures. Notice the tabs at 10 o’clock and 4 o’clock, with the rest of the edge formed vertically to create spacer dimension for assembly.

Customers with the older seal holder/wire spacer design may find the pump more difficult to disassemble because the wire spacer, slightly larger than the impeller opening, acts like a snap ring to keep the pump together as you tighten capscrews or nuts and studs.

  • If you see the ear of the wire spacer on only one side of the volute, you have this design. Grasp the ear gently with a vice grip pliers and push in slightly while lifting. This causes to the two ends of the wire spacer opposite the ear to close slightly and makes it easier to remove the motor and impeller assembly.
  • If you see the two tabs of the DP1966 seal holder with integral spacer on both sides of the volute and no wire ear in the slots, you have the current design. Lodged material may be binding the pump in the volute. Gently insert two blade screwdrivers between the bronze tab and the cast iron of the volute slots, twisting gently to dislodge the material. Be careful; inserting the screw driver blades too deeply can cut the volute gasket, necessitating its replacement (one is included with the seal and gasket kit).

Pumps made before 1982 use the older “A” design pump. You can find instructions for that design in current parts lists and service manuals.

What is a float block?

Volume 2/ Issue 2 / February 2015

A float block secures the float and operating mechanism to prevent damage during shipping. It’s installed at the factory, in one of the equalizing tappings and needs to be removed when you install the control.

Controls installed by boiler manufacturers also have a float block. It’s located in an extra tapping (see Figure 1) so the manufacturer can use the equalizing tappings to install the control. These controls have a “B” in the model or catalog number (e.g., 150S-B)—but note that our price sheets may not show the “B.” The only difference between a standard unit and one with a “B” is the extra tapping. The operation and the replacement parts are the same.

The easiest way to determine what control or parts to purchase is to drop the “B” from the model number, then check the price sheets and parts catalog for a standard unit. For instance, a 150S-B-MD becomes a 150S-MD, and a 25A-B becomes a 25A. Always refer to the McDonnell & Miller Replacement Parts Catalog, MM-701, for a complete breakdown of repair parts.

Why do the switch setpoints change?
The bellows on Series 150/150S units (mercury or snap switch) is pressure-sensitive. At higher pressures, the bellows is stiffer, requiring more force to move it. At lower pressures, the bellows is more pliable, requiring less force to move it. Consequently, at lower pressures, the on/off points tend to narrow. The chart shows how setpoints narrow or change from factory settings at 150psi, as the bellows reacts to pressure. Narrowing happens in both original mercury switch units and snap switch units.

The lower burner-off setpoint for the MD unit is intended to reduce burner cycling. This lower setpoint provides extra distance to help prevent nuisance burner shutdowns.

How long have MD models been available?
The Series 150-MD models were created in the mid-1980s, providing a control with factory settings to compensate for setpoints narrowing at lower pressures. Introduced on mercury switch units when the knurled adjustment screws were changed to nonadjustable screws, they are also offered with the new snap switch Series 150S.

It’s common—but wrong—to think that burner cycling occurs only with Series 150S (with snap switch). Remember, it’s the pressure the bellows senses that changes the setpoints, and that happens with both types of units.

 

Series 150S/157S have a monel bellow which is pressure sensitive. The operation points will shift as pressure decreases.

The operation points will shift as pressure decreases.

 

What’s a good starting point for troubleshooting?
Troubleshooting steam system problems can be difficult and frustrating. The control reacts to the water level in the boiler and may be doing its job. However, some other system component may not be operating properly. Start the troubleshooting process with these questions.

  • Is the pump sized properly and operating at full capacity?
  • Have the system dynamics changed from original installation?
  • Is the feedwater piping clean, without obstructions?
  • Are feedwater valves working properly?

Troubleshoot the whole system, not just the LWCO.

Volume 1 / Issue 1 / May 2015

“Reliable Water”, that’s what you hear from Duane Janssen, superintendent of Ridglea Country Club in Fort Worth Texas. Duane has been working for Ridglea Country Club for 20 years, and has been an Flowtronex fan his whole life. That was verified when Duane’s father recently visited our factory to see Duane’s new turf station. Duane’s father was also a golf course superintendent for many years. Like father like son, Duane’s father also selected Flowtronex for his pump stations on his golf courses, as they ran for decades in the tough southern environment. Ridglea Country Club is a testament to our quality. For the last 28 years, this course has relied on only one pump station: Flowtronex #1617 commissioned in 1987.

With the ever tightening water restrictions here in Texas, Duane has decided to take advantage of Flowtronex’s best in the industry software program, PACE, which delivers leading technology in the management of pressure and power of the pump station. Station #16399 is on the way to Ridglea Country Club and follows almost 15,000 stations built since they received their first station. When you add that to the energy savings of newer more efficient motors it translates into energy and water savings for the club. Duane will be ordering another Flowtronex station when their next golf course is ready. And what about old station #1617? It is still in great condition after all these years!

Flowtronex excellent products stand the test of time from generation to generation. According to Duane, “we make water reliable”.

Volume 1 / Issue 1 / May 2015

The Short Circuit Current Rating (SCCR) of an industrial control panel represents the maximum short circuit current that the panel can withstand before the equipment becomes damaged beyond the defined acceptance criteria. While this maximum short circuit current can vary from site to site, the SCCR of any control panel is determined by the components
inside of it.

One of the most effective methods to increase a panel’s SCCR is to use current limiting fuses instead of circuit breakers. These fuses, which have a high SCCR themselves, limit the amount of fault current that will affect the components on the circuit they are feeding. This allows for more flexibility in choosing the other components while still maintaining a high SCCR.

Another benefit of using fuses over circuit breakers is that to achieve an acceptable SCCR with a circuit breaker, one often has to use a specific component.

A circuit breaker/contactor combination may have a high SCCR, which is a result of testing. If that circuit breaker needs to be replaced, it has to be done so with the same manufacturer and model of circuit breaker, otherwise the SCCR may be decreased. Fuses can be replaced using any similar type fuse, regardless of the manufacturer, without affecting the SCCR.

Fuses also have the advantage in versatility, as their straight voltage rating means they can be used in any type of supply voltage. When using a breaker, which can have “slash” voltage ratings, the type of supply voltage must be taken into account. With fuses, as long as their voltage rating meets the supply voltage, there is no need to take the type of system into consideration.

Finally, over time and environmental changes, a breaker’s operation time may vary, resulting in delayed actions that can lead to hazardous scenarios. Fuses are less affected by age or environmental factors, providing more reliability while requiring less maintenance.

How to size a condensate return unit

$

Volume 2/ Issue 3/ May 2015

Facilities with their own boiler plant almost always have a closed loop system and require condensate to be as hot as possible upon return to the boiler. Conversely, steam condensate return pumps require subcooling to prevent cavitation or condensate flashing to vapor at the pump impellers’ suction eye. The degree of subcooling varies with the hydraulic design and pump characteristics.

We’ve previously mentioned the effect of temperature on NPSHA vs. NPSHR of the pump. Forgetting that effect when you pick a condensate return unit is a sure path to trouble. So, what do you need to know when sizing a condensate return pump?

 

Start with the load

Boilers are rated to tell you how much steam they can put out, in terms of boiler horsepower, pounds per hour of steam, BTUs or other ratings. It makes sense to convert the information you get from the engineer or customer into common terms across the system. When everything is said and done, what comes back from the boiler as condensate is .000496 gpm per 1 sq ft EDR. Rounding off, the boiler puts out half a gallon per minute of water in the form of steam per 1000 sq ft. EDR. When the steam cools and turns back to water, that’s the condensate you have to deal with.

Some common conversion factors:
Multiply Boiler Horsepower (BHP) by 34.5 = Lb. of steam (water per hour (lb/hr)
Multiply Boiler Horsepower (BHP) by 0.0069 = Gallons of water per minute (gpm)
Multiply Boiler Horsepower (BHP) by 33,479 = BTU
Multiply Boiler Horsepower (BHP) by 139 = Square feet of equivalent direct radiation (sq ft. EDR)

 

Look at the evaporation rate

Knowing how much water, or water as steam, the boiler can put out is good, but don’t pick a pump size yet. ASHRAE recommends sizing your return pump for two to three times the boiler’s evaporation rate—so the return unit can return condensate faster than the boiler can put it out.

Think about it: All boilers have a marked water line and optimum steaming levels. If the boiler starts pushing out steam, and your system can return condensate only as fast as the boiler puts it out, then as the water level falls and condensate returns, you can only keep up at the lower water line…not good for the boiler. Your optimum steaming level goes out the window, and the boiler soon after. If you send extra makeup water into the boiler, you must deal with it at some point, or you’ll flood the boiler when the boiler stops and the condensate plus the extra water return. Even worse, adding cold city makeup water to a steaming boiler will cause the steaming process to shut down quicker than the mouth of a toddler facing a spoonful of peas.

What about temperature? Condensate return units are designed to collect the returns and move the condensate along quickly and efficiently, minimizing heat loss and thus the energy required to heat it back to steam. With prices for light sweet crude hovering around $50 to $60 a barrel, saving energy can put a pretty penny in your pocket. So hotter is better, right?

Hold on. Remember what we said about NPSHA and NPSHR. First, when temperature goes up, NPSHA goes down. And when the NPSHR (required) of the pump is greater than the NPSHA (available) of the condensate, our old friend cavitation appears. The pennies you “saved” by making the returned condensate as hot as possible will probably go to pump repair. We’ll come back to this. For now, the next step is to figure out your discharge pressure requirement.

 

Calculate required discharge pressure

The required condensate unit discharge pressure includes:
• the static head lift,
• the friction loss in the piping (including pipe, fittings and valves),
• and any pressure that has to be overcome in the receiving vessel.
Manufacturers and ASHRAE generally recommend that when these values total less than 50 psi, you add 5 psi. For totals over 50 psi, add 10 psi.

This can be a daunting calculation; you have to find out how much pipe there is, what size it is, and the number of elbows, unions, etc. Don’t forget the isolation valves, check valves and plug cock (see previous article on balancing). As water flows through each of these, friction slows condensate and reduces pressure.

Refer to the charts, submittals and anything else you can grab to determine the value for each of these (sometimes called or expressed as a ∆p), and total it all up. The result is generally expressed in feet of head. If you’re transferring back to a vented boiler feed unit, add the 5 (or 10) psi to get your required discharge pressure for the condensate unit.

But remember—required discharge pressure also includes any pressure in the vessel that you’re pumping into. If that vessel is a pressurized deaerator, you have to add the maximum deaerator pressure plus the pressure drop across the spray nozzle (on some types), because that must be overcome to get condensate into the deaerator. If you’re pumping directly into the boiler (a rare and less desirable option that we’ll discuss in another article), add the maximum boiler pressure.

 

Determine condensate return temperature

So, we now know what size pump by gpm, and what discharge pressure to size for. As we mentioned earlier, temperature’s effect on NPSH can affect which unit you pick. That means you need to determine condensate return temperature—not an easy task. If you’re selecting a new unit for an existing system, you can measure the temperature of the actual condensate at your desired recovery point. But for a new or redesigned system, you have to make the calculation before you actually turn on the system.

The return temperature matters because hotter means less NPSHA, and some pumps don’t like that. The hotter the water, the more limited the choices. Most pumped condensate return units operate from a vented tank. Remember, steam heating applications using thermostatic traps drain condensate around 160 to 180 degrees. At 180 degrees, a condensate pump mounted to a collection tank at the same level as the pump will have about 15 feet of NPSHA in the water. Most pumps handle this from a vented tank with no problem. But if the trap fails, and the temperature in the condensate tank rises to 212 degrees f., there is zero NPSH available. NPSH is still required, however, because it’s a function of the pump design. Having some NPSH required vs. no NPSH available is a problem at 212 degrees: The pump that could discharge condensate at 180 degrees will now cavitate.

Domestic® Pump Series CB

See how this changes things? Up to about 200 degrees, a standard centrifugal pump design generally works if properly sized for the duty point and NPSHA. From 200 to 210 degrees, you need more specialized (and somewhat more expensive) low NPSH pumps. From 210 to 212 degrees, about all you can do is move the tank above the pump to add NPSHA, in the form of a static column of water above the pump suction. That’s right, raising the tank provides additional NPSHA and lets you pump hotter water. Why not raise the tank even more? Because that takes more material, which costs more money, erasing the savings. Besides, return piping is seldom located high in the equipment space. It’s a matter of picking the right tool for the job.

 

Consider condensate tank sizing

You usually want one minute net storage in a condensate tank; remember, the sooner you collect and return condensate, the less heat it loses and the less energy required to heat back to steam. Keep in mind that “one minute of net storage” refers to one minute of pumping capacity in storage. If you size for one minute of return rate, the tank is undersized and forces the pump to short-cycle. That accelerates on/off frequency as well as the wear on the pump.

Putting it all together. You know the boiler can put out half a gallon per 1000 sq ft EDR per minute. Sizing for two times that to get the pump capacity means sizing your pump for 1 gpm per 1000 sq ft EDR. Let’s apply that to some typical boiler sizes.

For a boiler rated 100 BHP: Use the formula above to convert boiler horsepower: BHP X 139 = sq ft EDR. 100×139=13900. When you calculate the amount of steam put out, you get 6.9 gpm of water as steam. Let’s round that up to 7 gpm. Sizing the pump for twice the return rate means we’ll size for 14 gpm. Now apply the 1 gpm per 1000 sq ft EDR rule of thumb. Sizing the tank for the pumping capacity based on one minute net storage, you need a tank that is 14 gallons. If the manufacturer you use doesn’t offer a 14-gallon tank, choose the nearest size—but beware: In this example, a tank smaller than 14 gallons will not only collect condensate quicker and pump it back to the boiler hotter, but also lack the mass to provide the degree or two of sub cooling required to address NPSHA issues. Going smaller can also set the pump up to short cycle. It’s better to go to the nearest larger size than your 1 minute storage—in our example, 15 or 18 or 20 gallons.

 

The right equipment matters

Before the mid-1970s, most manufacturers sized for three times the boiler’s evaporation rate. Bigger was better—and boy, what a safety factor! Sizing for three times the evaporation rate meant the pumps were sized for 1.5 gpm per thousand square foot EDR. But when oil shortages hit the United States, and people lined up around the block to buy a tank of gasoline, and the cost of making steam rose, manufacturers gradually moved to sizing for two times the evaporation rate.

You can see how that makes a difference. A 15,000 sq ft EDR system puts out 7.44 gpm of condensate as steam. Sizing for twice that, you need a 14.88 gpm pump. Sizing for one minute net storage leads you to a 14- to 15-gallon collection vessel. In the Domestic/Hoffman pump products, you’d choose a 15 gpm unit with 14-gallon tank and, if you’re looking at a 20 psi requirement, the hp in 3500 rpm is 1/3 HP. Compare that to sizing for three times the evaporation rate. You’re forced to go to a 22 gpm pump and 23-gallon tank, and the HP increases to 1/2 HP. You end up with a bigger, more expensive unit. What’s more, since the evaporation rate doesn’t change, the condensate sits there longer until enough is collected to be pumped, giving up heat (energy) that has to be added back in at the boiler. The pump comes on less frequently, but the 1/2 HP pump costs more in electricity to run than the 1/3 HP pump.

That wraps up our tips on sizing condensate units. Watch for a future article on sizing boiler feed units—similar to the above, but with important differences.

Ten reasons steam-heating boilers flood

Volume 2/ Issue 3/ May 2015

Having problems with that steam-heating boiler’s water line? Is that boiler constantly flooding? And does that make your customer complain about not having enough heat?

Before you get mad at the automatic water feeder, look at what may be causing the flooding. Good troubleshooters never make decisions until they’ve examined all the clues.

 

Here are 10 common reasons steam-heating boilers flood

1. The water line surges, turning the automatic water feeder on and off. Surging begins when dirt and oil accumulate on the boiler water’s surface. As the steam tries to break free, it lifts the water, creating the surge. You can see this in the gauge glass. Since steam systems are open to the atmosphere, you occasionally need to clean them. Get rid of the surging, and you usually get rid of the flooding.

 

2. The water’s pH is too high. When steam condenses, it produces carbonic acid that can eat through wet-return lines. So service technicians often add chemicals to steam boilers to keep the pH from getting too low.  But it can be just as bad if the pH gets too high; that causes foaming, and foaming leads to trouble. Too much water flows from the boiler with the steam. That water loss sends the automatic feeder into action. Then the condensate returns, and the boiler floods. A good pH for a steam system ranges from 7 to 9. When the pH reaches 11, the water foams. The old-timer’s cure? Add vinegar to the boiler. Vinegar is acidic and helps bring the pH down.

 

3. The boiler has a tankless coil, and it’s leaking. City water pressure is greater than the pressure in a steam heating system. Even the smallest leak in a tankless coil will flood a boiler. Close the cold-water valve leading to the coil for a few hours and watch the gauge glass. If the flooding stops, you’ve probably found the culprit. Replace the tankless coil.

 

4. The system has a gravity return and motorized zone valves. When a motorized zone valve closes on a boiler that’s under pressure, the water backs into the closed zone’s return line. That brings on the automatic water feeder. The next time the motorized zone valve opens, the condensate returns and floods the boiler. Install quarter-inch bleed lines around the tops of the motorized zone valves. This lets through enough pressure to keep the water from backing out of the boiler, without letting through so much steam that the zone overheats.

 

5. The boiler is overfired. If the flame is too big, the steam’s exit velocity carries water from the boiler into the system. The automatic water feeder then replaces the “missing” water. When that water works its way back into the boiler, the boiler floods. Fire boilers to the connected piping-and ­radiation load. No more, and no less.

 

6. The automatic water feeder is positioned too high on the boiler. Some installers try to cover a tankless coil during the summer by adding nipples and elbows to the McDonnell & Miller Quick-Hook-Up fitting. That causes the feeder to sit too high on the gauge glass.

Normally, the feeder should open when the water line drops just above the low-water cutoff’s operating position. But if the feeder is too high, so is the low-water cutoff. That means the feeder will add too much water, and the returning condensate will flood the boiler every day.

 

7. The feed line is clogged with sediment. If you‘re using a float-operated feeder/cutoff combination, such as McDonnell & Miller’s 47-2, a plugged feed line can create a back-pressure that keeps the feed valve from shutting tightly. City water pressure will bleed through and flood the boiler. You can diagnose this problem by doing a broken-union test (see M&M’s instructions). lf you find a plugged feed line, replace it.

 

8. The feeder-bypass valve isn’t holding. The bypass around the feeder lets you fiII the boiler quickly. But if the shutoff valve in that line doesn’t hold tightly, the boiiler keeps taking on water until it floods. Again, the broken­ union test lets you quickly see whether that important valve is doing its job. If it’s not, replace it.

 

9. The piping around the boiler doesn’t meet the boiler manufacturer’s specs. Modern boilers make steam quickly . If the piping around the boiler is wrong, the boiler throws water into the piping. The automatic water feeder then replaces that water—and before long, the boiler is flooded. Take the time to check the piping on the job against what the boiler manufacturer calls for. If it doesn’t meet the specs, you have to repipe that boiler. Tough medicine, but it’s often the only cure.

 

10. Someone is adding water when you’re not there. Never dismiss this as a possible cause. If someone adds water to the boiler in the middle of the steaming cycle, the returning condensate will push the water level even higher, and the boiler will flood.

Talk to the homeowner or building superintendent. Make sure they understand how a steam system works, and what it needs in the way of feed water.

FROM CONCEPT TO CONSUMER, GOULDS WATER TECHNOLOGY IS ENGINEERED, ASSEMBLED AND TESTED IN AMERICA.

According to the American Water Works Association, average daily residential water use in the United States is 27.4 billion gallons. This domestic water is used for everything from lawn irrigation to cooking, cleaning and plumbing. By that account, it’s clear that water is essential to homeowners who take great pride in maintaining and improving their homes.

A consistent supply of water requires reputable, reliable and high quality pumps. Xylem’s Goulds Water Technology (GWT) brand pumps are engineered, tested and assembled to meet these homeowner needs with pride in craftsmanship.

DESIGNED FOR DECADES OF TROUBLE-FREE OPERATION

Xylem’s passion for solving domestic water challenges begins with innovative pump concepts, design and engineering work at the company’s facility in Seneca Falls, New York. As part of the design process, engineers explore virtually every possible use of these highly technical devices. Using 3-D software and advanced CAD simulations, they examine how the pumps will behave in scenarios ranging from normal everyday domestic water use, to rare or extreme water-related situations, as in the event of a drought that causes dry running conditions, or from abrasives such as sand.

Additionally, expertise in residential applications, including water pressure, wastewater and irrigation, enables Xylem engineers to design GWT pumps to last for decades with progressive technologies. Materials, such as cast iron, engineered composites and stainless steel ensure exceptional durability over time. Prototyping supports identification of design enhancements that address considerations ranging from geography and climate, to adverse system conditions.

“Design and engineering is the first and a critical step in providing the highest quality products in the industry to our trade customers,” said Chris Preston, Manager, Residential Water Products, Xylem. “We design our pumps with our audiences, like well drillers and pump installers, in mind, making sure that our products have the necessary features for smooth, trouble-free installation.”

Expert engineers take the entire home’s water systems into account when designing each pump, enabling the company to build system solutions that can result in cost, energy and time savings for installers and homeowners.

ASSEMBLED WITH CARE

The next step in producing the highest quality pumps in the industry is putting them together with a highly critical eye and attention to detail. Twenty minutes down the road from Xylem’s Seneca Falls location where residential water and wastewater pumps are engineered, more than 200 dedicated workers are producing durable pump components, hand-assembling products, and fulfilling orders at the 300,000-square-foot Xylem production facility in Auburn, New York.

Here, employees are meticulous in their craftsmanship, building nearly 2,500 residential and wastewater pumps each day. The comprehensive portfolio of products built here include 4-inch and 6-inch submersible pumps, jet pumps, sump, effluent and sewage pumps, prepackaged systems, multi-stage and end suction pumps, and a host of other accessories and controls.

The facility itself is designed and equipped to ensure high product quality and reliability. In fact, Xylem’s Auburn plant recently completed a three-year Lean Transformation program, minimizing errors in production, creating a safer work environment, and supporting some of the best on time performance and delivery to lead times in the industry.

“The Lean Transformation helped create a more flexible cross-trained work force, ensuring that highly trained operators are available at all times,” said Michael Foster, Manager, Goulds Water Technology Manufacturing Engineering. “Additional error-proofing steps were implemented to ensure that a quality product is being passed to the next step in the process.”

This relentless attention to detail was also a primary factor in earning the facility ISO-9001 certification, which further sets the global water technology leader apart from its competitors.

Xylem and its employees exhibit as much care and consideration in the final stages of assembly, as they do throughout the rest of the production process. Pumps are packaged and shipped with attention to product presentation and durability to ensure a positive unboxing experience for customers.

PERFORMANCE COUNTS

Precise assembly is followed by rigorous performance testing, an integral part of the production process for all GWT pumps. Every pump is hydraulically and electrically tested to Xylem’s industry-leading safety and performance standards. The company’s commitment to quality leaves nothing to chance during production.

Take GWT 4-inch submersible pumps, which go through two test cycles. First, the pump is tested for liquid end hydraulic performance in accordance with Hydraulic Institute standards. This involves submerging the pump in water, connecting the pipe and wiring and then running the product to assess performance. Then, the motor undergoes an electrical test where electrical characteristics (i.e., watts) are confirmed and verified a second time to the published performance.

By the time these products are ready for market, many have undergone more than 1 million testing cycles comprising factors such as mechanical strength, durability, hydraulic validation and electrical checks in the Xylem lab, located in Seneca Falls, New York.

Each motor and pump receives a bar code containing information from the test process. By coding the motors and pumps, plant workers can guarantee they match during assembly. Labels, serial number tracking and production records for each unit identify which assembly line produced it and which operator assembled it.

To ensure quality of the final product, the data matrix label – which includes the model and serial numbers, test performance data, date and time stamp – doesn’t print unless both pump and motor pass their tests. This process, currently used for the production of the 4-inch submersible pumps, is important because it enables the installer to scan the product and understand how it is going to perform before they invest time and money to install it.

“A great sense of pride and responsibility comes with knowing that each product can be traced to its origins and was assembled here in the U.S.,” said Foster.

BEYOND THE BUILD

Xylem’s superior performance and quality testing are matched by the company’s training and educational offering for the residential and wastewater market. The Seneca Falls facility hosts the Campbell Education Center and laboratory, which has educated thousands of people about Goulds Water Technology products and taught troubleshooting techniques for more than 30 years.

The GWT Factory School, as it’s called, was revamped in 2012, providing distributors, dealers, engineers and other industry professionals with hands-on exposure to the latest pumping technologies, and a suite of courses that span the GWT product line and related systems.

The lab comprises mobile demonstration units, network and Wi-Fi enabled equipment, LED TVs and configurable work stations for real-world experience in residentialSTUDY and wastewater pump systems. Complementary to the interactive lab environment is practical education in the classroom outfitted with smart technology.

“We believe that investment in education is critical to the success of our industry,” said Tom Stephan, Manager, Goulds Water Technology Training. “Because we provide a full system offering and have the ability to teach to specific residential applications, we are able train beyond the product.”

Education is also important to Xylem customers like Texas-based Whisenant & Lyle Water Services, which has been purchasing GWT pumps through Austin Pump and Supply for more than 15 years. “We’ve had a good working relationship,” said Pat Lyle, Vice President and General Manager, Whisenant & Lyle Water Services. “Some of it is due to the fact that Goulds Water Technology goes the extra mile with education and taking people to where the pumps are produced, and seeing the people who produce them.”

Tyler Sutliff, president of Whisenant & Lyle, agrees. “We are learning about technology that we’re using now as well as technology coming online in the future. Xylem is keenly focused on helping support our business, which, in turns, helps us grow our business,” Sutliff said.

From concept and engineering to assembly, testing and installation, GWT products continue to be produced with the conscientious pride of a workforce dedicated to quality, the credibility of a 150-year old company, and the high reliability of components and processes critical to ensuring an excellent pump ownership experience.
