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. Atmospheric pressure 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-10110-E-02 8/063WILDEN PUMP & ENGINEERING, LLC

Section 6S U G G E S T E D I N S TA L L AT I O NWilden 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.mufflers 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: P
