Section 3HOW IT WORKS—PUMPThe Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow patternthrough the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.FIGURE 1 The air valve directs pressurizedair to the back side of diaphragm A. Thecompressed air is applied directly to theliquid column separated by elastomericdiaphragms. The diaphragm acts asa separation membrane between thecompressed air and liquid, balancing theload and removing mechanical stressfrom the diaphragm. The compressedair moves the diaphragm away fromthe center of the pump. The oppositediaphragm is pulled in by the shaftconnected to the pressurized diaphragm.Diaphragm B is on its suction stroke; airbehind the diaphragm has been forcedout to atmosphere through the exhaustport of the pump. The movement ofdiaphragm B toward the center of thepump creates a vacuum within chamber B.Atmospheric pressure forces fluid intothe inlet manifold forcing the inlet valveball off its seat. Liquid is free to movepast the inlet valve ball and fill the liquidchamber (see shaded area).FIGURE 2 When the pressurized diaphragm,diaphragm A, reaches the limit of its dischargestroke, the air valve redirects pressurizedair to the back side of diaphragm B. Thepressurized air forces diaphragm B awayfrom the center while pulling diaphragm Ato the center. Diaphragm B is now on itsdischarge stroke. Diaphragm B forces theinlet valve ball onto its seat due to thehydraulic forces developed in the liquidchamber and manifold of the pump. Thesesame hydraulic forces lift the dischargevalve ball off its seat, while the oppositedischarge valve ball is forced onto its seat,forcing fluid to flow through the pumpdischarge. The movement of diaphragm Atoward the center of the pump creates avacuum within liquid chamber A. Atmosphericpressure forces fluid into the inletmanifold of the pump. The inlet valve ballis forced off its seat allowing the fluid beingpumped to fill the liquid chamber.FIGURE 3 At completion of the stroke,the air valve again redirects air to theback side of diaphragm A, which startsdiaphragm B on its exhaust stroke. Asthe pump reaches its original startingpoint, each diaphragm has gone throughone exhaust and one discharge stroke.This constitutes one complete pumpingcycle. The pump may take several cyclesto completely prime depending on theconditions of the application.HOW IT WORKS—AIR DISTRIBUTION SYSTEMThe Pro-Flo ® patented air distribution system incorporates twomoving parts: the air valve spool and the pilot spool. The heart ofthe system is the air valve spool and air valve. This valve designincorporates an unbalanced spool. The smaller end of the spoolis pressurized continuously, while the large end is alternatelypressurized then exhausted to move the spool. The spool directspressurized air to one air chamber while exhausting the other.The air causes the main shaft/diaphragm assembly to shift toone side — discharging liquid on that side and pulling liquid inon the other side. When the shaft reaches the end of its stroke,the inner piston actuates the pilot spool, which pressurizes andexhausts the large end of the air valve spool. The repositioningof the air valve spool routes the air to the other air chamber.WIL-10330-E-01 3 WILDEN PUMP & ENGINEERING, LLC

HOW TO USE THIS EMS CURVEExample 2.1SETTING 4 PERFORMANCE CURVEEMS CURVEEMS FlowSettings 1 & 2Figure 4Example data point = 10.2 gpm0.49flow multiplierFigure 5This is an example showing how to determine the inlet airpressure and the EMS setting for your Pro-Flo X pump tooptimize the pump for a specific application. For this examplewe will be using an application requirement of 18.9 lpm(5 gpm) flow rate against 2.8 bar (40 psig) discharge pressure.This example will illustrate how to calculate the air consumptionthat could be expected at this operational point.DETERMINE EMS SETTINGStep 1: Establish inlet air pressure. Higher air pressureswill typically allow the pump to runmore efficiently, however, available plant airpressure can vary greatly. If an operatingpressure of 6.9 bar (100 psig) is chosen whenplant air frequently dips to 6.2 bar (90 psig)pump performance will vary. Choose an operatingpressure that is within your compressedair system's capabilities. For this example wewill choose 4.1 bar (60 psig).Step 2: Determine performance point at setting 4. Forthis example an inlet air pressure of 4.1 bar(60 psig) inlet air pressure has been chosen.Locate the curve that represents the performanceof the pump with 4.1 bar (60 psig) inletair pressure. Mark the point where this curvecrosses the horizontal line representing 2.8bar (40 psig) discharge pressure. After locatingthis point on the flow curve, draw a verticalline downward until reaching the bottomscale on the chart and identify the flow rate.In our example it is 38.6 lpm (10.2 gpm). Thisis the setting 4 flow rate. Observe the locationof the performance point relative to airconsumption curves and approximate airconsumption value. In our example setting4 air consumption is 24 Nm 3 /h (14 scfm).See figure 4.Step 3: Determine flow X Factor. Divide the requiredflow rate 18.9 lpm (5 gpm) by the setting 4 flowrate 38.6 lpm (10.2 gpm) to determine the flowX Factor for the application.5 gpm / 10.2 gpm = 0.49 (flow X Factor)Step 4: Determine EMS setting from the flowX Factor. Plot the point representing the flowX Factor (0.49) and the application dischargepressure 2.8 bar (40 psig) on the EMS curve.This is done by following the horizontal 2.8bar (40 psig) psig discharge pressure line untilit crosses the vertical 0.49 X Factor line. Typically,this point lies between two flow EMSsetting curves (in this case, the point lies betweenthe flow curves for EMS setting 1 and2). Observe the location of the point relativeto the two curves it lies between and approximatethe EMS setting (figure 5). For more preciseresults you can mathematically interpolatebetween the two curves to determine theoptimal EMS setting.For this example the EMS setting is 1.8.WILDEN PUMP & ENGINEERING, LLC 8 PX15 Performance

For any EMS setting and dischargepressure, the “X factor” is used as a multiplierwith the original values from the setting4 performance curve to calculate the actualflow and air consumption values for that specificEMS setting. Note: you can interpolatebetween the setting curves for operation atintermediate EMS settings.The Efficiency Management System (EMS) can be used to optimize the performance of your Wilden pump forspecific applications. The pump is delivered with the EMS adjusted to setting 4, which allows maximum flow.EXAMPLEA PX15 aluminum, Ultra-Flex-fitted pump operating at EMS setting 4,achieved a flow rate of 719 lpm (190 gpm) using 255 Nm 3 /h (150 scfm)of air when run at 6.9 bar (100 psig) air inlet pressure and 0.7 bar (10psig) discharge pressure (See dot on performance curve).The end user did not require that much flow and wanted to reduceair consumption at his facility. He determined that EMS setting 1would meet his needs. At 0.7 bar (10 psig) discharge pressure andEMS setting 1, the flow “X factor” is 0.48 and the air “X factor” is0.22 (see dots on EMS curve).Multiplying the original setting 4 values by the “X factors” providesthe setting 1 flow rate of 345 lpm (91 gpm) and an air consumptionof 56 Nm 3 /h (33 scfm). The flow rate was reduced by 52% while theair consumption was reduced by 78%, thus providing increased efficiency.For a detailed example for how to set your EMS, see beginning ofperformance curve section.Caution: Do not exceed 8.6 bar (125 psig) air supply pressure.PX15 Performance 13 WILDEN PUMP & ENGINEERING, LLC


Section 5CPX15 METAL SUCTIONLIFT CAPABILITYSUCTION LIFT CURVESSuction lift curves are calibrated for pumps operatingat 305 m (1,000') above sea level. This chart is meantto be a guide only. There are many variables whichcan affect your pump’s operating characteristics. Thenumber of intake and discharge elbows, viscosity ofpumping fluid, elevation (atmospheric pressure) andpipe friction loss all affect the amount of suction liftyour pump will attain.WILDEN PUMP & ENGINEERING, LLC 14 WIL-10330-E-01


Section 6SUGGESTED INSTALLATIONWilden pumps are designed to meet the performancerequirements of even the most demanding pumpingapplications. They have been designed and manufacturedto the highest standards and are available in a variety ofliquid path materials to meet your chemical resistanceneeds. Refer to the performance section of this manual foran in-depth analysis of the performance characteristics ofyour pump. Wilden offers the widest variety of elastomeroptions in the industry to satisfy temperature, chemicalcompatibility, abrasion resistance and flex concerns.The suction pipe size should be at least the equivalent orlarger than the diameter size of the suction inlet on yourWilden pump. The suction hose must be non-collapsible,reinforced type as these pumps are capable of pulling a highvacuum. Discharge piping should also be the equivalentor larger than the diameter of the pump discharge whichwill help reduce friction losses. It is critical that all fittingsand connections are airtight or a reduction or loss of pumpsuction capability will result.INSTALLATION: Months of careful planning, study,and selection efforts can result in unsatisfactory pumpperformance if installation details are left to chance.Premature failure and long term dissatisfaction can beavoided if reasonable care is exercised throughout theinstallation process.LOCATION: Noise, safety, and other logistical factors usuallydictate where equipment will be situated on the productionfloor. Multiple installations with conflicting requirementscan result in congestion of utility areas, leaving few choicesfor additional pumps.Within the framework of these and other existing conditions,every pump should be located in such a way that six keyfactors are balanced against each other to maximumadvantage.ACCESS: First of all, the location should be accessible. Ifit’s easy to reach the pump, maintenance personnel willhave an easier time carrying out routine inspections andadjustments. Should major repairs become necessary, easeof access can play a key role in speeding the repair processand reducing total downtime.AIR SUPPLY: Every pump location should have an air linelarge enough to supply the volume of air necessary toachieve the desired pumping rate. Use air pressure up toa maximum of 8.6 bar (125 psig) depending on pumpingrequirements.For best results, the pumps should use a 5µ (micron) airfilter, needle valve and regulator. The use of an air filterbefore the pump will ensure that the majority of any pipelinecontaminants will be eliminated.SOLENOID OPERATION: When operation is controlled by asolenoid valve in the air line, three-way valves should beused. This valve allows trapped air between the valve andthe pump to bleed off which improves pump performance.Pumping volume can be estimated by counting the numberof strokes per minute and then multiplying the figure by thedisplacement per stroke.MUFFLER: Sound levels are reduced below OSHAspecifications using the standard Wilden muffler. Othermufflers can be used to further reduce sound levels, butthey usually reduce pump performance.ELEVATION: Selecting a site that is well within the pump’sdynamic lift capability will assure that loss-of-prime issues willbe eliminated. In addition, pump efficiency can be adverselyaffected if proper attention is not given to site location.PIPING: Final determination of the pump site should not bemade until the piping challenges of each possible locationhave been evaluated. The impact of current and futureinstallations should be considered ahead of time to makesure that inadvertent restrictions are not created for anyremaining sites.The best choice possible will be a site involving the shortestand straightest hook-up of suction and discharge piping.Unnecessary elbows, bends, and fittings should be avoided.Pipe sizes should be selected to keep friction losses withinpractical limits. All piping should be supported independentlyof the pump. In addition, the piping should be aligned toavoid placing stress on the pump fittings.Flexible hose can be installed to aid in absorbing the forcescreated by the natural reciprocating action of the pump. If thepump is to be bolted down to a solid location, a mountingpad placed between the pump and the foundation will assistin minimizing pump vibration. Flexible connections betweenthe pump and rigid piping will also assist in minimizingpump vibration. If quick-closing valves are installed at anypoint in the discharge system, or if pulsation within a systembecomes a problem, a surge suppressor (SD Equalizer ® )should be installed to protect the pump, piping and gaugesfrom surges and water hammer.If the pump is to be used in a self-priming application, makesure that all connections are airtight and that the suction lift iswithin the model’s ability. Note: Materials of construction andelastomer material have an effect on suction lift parameters.Please refer to the performance section for specifics.When pumps are installed in applications involving floodedsuction or suction head pressures, a gate valve should beinstalled in the suction line to permit closing of the line forpump service.Pumps in service with a positive suction head are most efficientwhen inlet pressure is limited to 0.5–0.7 bar (7–10 psig).Premature diaphragm failure may occur if positive suctionis 0.7 bar (10 psig) and higher.SUBMERSIBLE APPLICATIONS: Pro-Flo X pumps can beused for submersible applications, when using the Pro-FloX submersible option. Turbo-Flo pumps can also beused for submersible applications.NOTE: Pro-Flo ® and Accu-Flo pumps are not submersible.ALL WILDEN PUMPS ARE CAPABLE OF PASSING SOLIDS.A STRAINER SHOULD BE USED ON THE PUMP INTAKE TOENSURE THAT THE PUMP'S RATED SOLIDS CAPACITY ISNOT EXCEEDED.CAUTION: DO NOT EXCEED 8.6 BAR (125 PSIG) AIRSUPPLY PRESSURE.WIL-10330-E-01 15 WILDEN PUMP & ENGINEERING, LLC


SUGGESTED INSTALLATIONThis illustration is a genericrepresentation of an air-operateddouble-diaphragm pump.NOTE: In the event of a power failure, the shut off valveshould be closed, if the restarting of the pump is notdesirable once power is regained.AIR OPERATED PUMPS: To stop the pump fromoperating in an emergency situation, simply close theshut off valve (user supplied) installed in the air supplyline. A properly functioning valve will stop the air supplyto the pump, therefore stopping output. This shut offvalve should be located far enough away from thepumping equipment such that it can be reached safelyin an emergency situation.WILDEN PUMP & ENGINEERING, LLC 16 WIL-10330-E-01


SUGGESTED OPERATION & MAINTENANCEOPERATION: The PX15 is pre-lubricated, and does notrequire in-line lubrication. Additional lubrication willnot damage the pump, however if the pump is heavilylubricated by an external source, the pump’s internallubrication may be washed away. If the pump is thenmoved to a non-lubricated location, it may need to bedisassembled and re-lubricated as described in theASSEMBLY/DISASSEMBLY INSTRUCTIONS.Pump discharge rate can be controlled by limiting thevolume and/or pressure of the air supply to the pump.An air regulator is used to regulate air pressure. A needlevalve is used to regulate volume. Pump discharge ratecan also be controlled by throttling the pump dischargeby partially closing a valve in the discharge line of thepump. This action increases friction loss which reducesflow rate. (See Section 5.) This is useful when the needexists to control the pump from a remote location.When the pump discharge pressure equals or exceedsthe air supply pressure, the pump will stop; no bypassor pressure relief valve is needed, and pump damagewill not occur. The pump has reached a “deadhead”situation and can be restarted by reducing the fluiddischarge pressure or increasing the air inlet pressure.The Wilden PX15 pump runs solely on compressed airand does not generate heat, therefore your processfluid temperature will not be affected.MAINTENANCE AND INSPECTIONS: Since eachapplication is unique, maintenance schedules maybe different for every pump. Frequency of use, linepressure, viscosity and abrasiveness of process fluidall affect the parts life of a Wilden pump. Periodicinspections have been found to offer the bestmeans for preventing unscheduled pump downtime.Personnel familiar with the pump’s construction andservice should be informed of any abnormalities thatare detected during operation.RECORDS: When service is required, a record shouldbe made of all necessary repairs and replacements.Over a period of time, such records can become avaluable tool for predicting and preventing futuremaintenance problems and unscheduled downtime. Inaddition, accurate records make it possible to identifypumps that are poorly suited to their applications.TROUBLESHOOTINGPump will not run or runs slowly.1. Ensure that the air inlet pressure is at least 0.4 bar(5 psig) above startup pressure and that the differentialpressure (the difference between air inlet and liquiddischarge pressures) is not less than 0.7 bar (10 psig).2. Check air inlet filter for debris (see recommendedinstallation).3. Check for extreme air leakage (blow by) whichwould indicate worn seals/bores in the air valve,pilot spool, main shaft.4. Disassemble pump and check for obstructionsin the air passageways or objects which wouldobstruct the movement of internal parts.5. Check for sticking ball check valves. If materialbeing pumped is not compatible with pumpelastomers, swelling may occur. Replace ballcheck valves and seals with proper elastomers.Also, as the check valve balls wear out, theybecome smaller and can become stuck in theseats. In this case, replace balls and seats.6. Check for broken inner piston which will cause theair valve spool to be unable to shift.7. Remove plug from pilot spool exhaust.Pump runs but little or no product flows.1. Check for pump cavitation; slow pump speeddown to allow thick material to flow into liquidchambers.2. Verify that vacuum required to lift liquid is notgreater than the vapor pressure of the materialbeing pumped (cavitation).3. Check for sticking ball check valves. If material beingpumped is not compatible with pump elastomers,swelling may occur. Replace ball check valves andseats with proper elastomers. Also, as the checkvalve balls wear out, they become smaller and canbecome stuck in the seats. In this case, replace ballsand seats.Pump air valve freezes.1. Check for excessive moisture in compressedair. Either install a dryer or hot air generator forcompressed air. Alternatively, a coalescing filter maybe used to remove the water from the compressedair in some applications.Air bubbles in pump discharge.1. Check for ruptured diaphragm.2. Check tightness of outer pistons (refer to Section 7).3. Check tightness of fasteners and integrity ofo-rings and seals, especially at intake manifold.4. Ensure pipe connections are airtight.Product comes out air exhaust.1. Check for diaphragm rupture.2. Check tightness of outer pistons to shaft.WIL-10330-E-01 17 WILDEN PUMP & ENGINEERING, LLC

ASSEMBLY:REASSEMBLY HINTS & TIPSUpon performing applicable maintenance to the airdistribution system, the pump can now be reassembled.Please refer to the disassembly instructions for photosand parts placement. To reassemble the pump, followthe disassembly instructions in reverse order. The airdistribution system needs to be assembled first, thenthe diaphragms and finally the wetted path. Please findthe applicable torque specifications on this page. Thefollowing tips will assist in the assembly process.• Lubricate air valve bore, center section shaft andpilot spool bore with NLGI grade 2 white EP greaseor equivalent.• Clean the inside of the center section shaft bushing toensure no damage is done to new shaft seals.• A small amount NLGI grade 2 white EP grease canbe applied to the muffler and air valve gaskets tolocate gaskets during assembly.• Make sure that the exhaust port on the muffler plateis centered between the two exhaust ports on thecenter section.• Stainless bolts should be lubed to reduce thepossibility of seizing during tightening.• Use a mallet to tamp lightly on the large clampbands to seat the diaphragm before tightening.PRO-FLO X MAXIMUM TORQUE SPECIFICATIONSDescription of PartAir ValveAir Chamber/Center BlockInner Piston RingOuter Pistons, Rubber & PTFEOuter Pistons, Ultra-FlexSmall Clamp BandsLarge Clamp Bands (Rubber-Fitted)Large Clamp Bands (PTFE-Fitted)Torque13.6 N•m (120 in-lbs)27.1 N•m (20 ft-lbs)19.0 N•m (14 ft-lbs)135.6 N•m (100 ft-lbs)135.6 N•m (100 ft-lbs)15.5 N•m (137 in-lbs)61.0 N•m (45 ft-lbs)61.0 N•m (45 ft-lbs)SHAFT SEAL INSTALLATION:PRE-INSTALLATION• Once all of the old seals have been removed, theinside of the bushing should be cleaned to ensureno debris is left that may cause premature damageto the new seals.INSTALLATIONThe following tools can be used to aid in the installationof the new seals:Needle Nose PliersPhillips ScrewdriverElectrical Tape• Wrap electrical tape around each leg of the needle nosepliers (heat shrink tubing may also be used). This is doneto prevent damaging the inside surface of the new seal.• With a new seal in hand, place the two legs of the needlenose pliers inside the seal ring. (See Figure A.)• Open the pliers as wide as the seal diameter will allow,then with two fingers pull down on the top portion ofthe seal to form kidney bean shape. (See Figure B.)• Lightly clamp the pliers together to hold the seal intothe kidney shape. Be sure to pull the seal into as tightof a kidney shape as possible, this will allow the seal totravel down the bushing bore easier.• With the seal clamped in the pliers, insert the seal intothe bushing bore and position the bottom of the sealinto the correct groove. Once the bottom of the seal isseated in the groove, release the clamp pressure on thepliers. This will allow the seal to partially snap back to itsoriginal shape.• After the pliers are removed, you will notice a slightbump in the seal shape. Before the seal can be properlyresized, the bump in the seal should be removed asmuch as possible. This can be done with either thePhillips screwdriver or your finger. With either the sideof the screwdriver or your finger, apply light pressureto the peak of the bump. This pressure will cause thebump to be almost completely eliminated.• Lubricate the edge of the shaft with NLGI grade 2 whiteEP bearing grease.• Slowly insert the center shaft with a rotating motion.This will complete the resizing of the seal.• Perform these steps for the remaining seals.Figure ASHAFT SEALFigure BNEEDLE NOSEPLIERSSHAFT SEALTAPETAPEWILDEN PUMP & ENGINEERING, LLC 24 WIL-10330-E-01
