Section 1Precautions - Read First!CAUTION: Before any maintenance or repair isattempted, the compressed air line to the pump shouldbe disconnected and all air pressure allowed to bleedfrom pump. Disconnect all intake, discharge and airlines. Drain the pump by turning it upside down andallowing any fluid to flow into a suitable container.TEMPERATURE LIMITS:NeopreneBuna-NEPDMFKMWil-Flex PolyurethaneSaniflex PTFEFlouoro-Seal –17.8 C to 93.3 C–12.2 C to 82.2 C–51.1 C to 137.8 C–40 C to 176.7 C–40 C to 107.2 C12.2 C to 65.6 C–28.9 C to 104.4 C–28.9 C to 148.9 C0 F to 200 F10 F to 180 F–60 F to 280 F–40 F to 350 F–40 F to 225 F10 F to 150 F–20 F to 220 F–20 F to 300 FCAUTION: Blow out air line for 10 to 20 secondsbefore attaching to pump to make sure all pipe linedebris is clear. Use an in-line air filter. A 5μ (micron)air filter is recommended.NOTE: Tighten clamp bands and retainers prior toinstallation. Fittings may loosen during transportation.NOTE: Not all materials are available for all models. See "Wilden PumpDesignation System " on page 5 for material options for your pump.NOTE: When installing PTFE diaphragms, it isimportant to tighten outer pistons simultaneously(turning in opposite directions) to ensure tight fit.CAUTION: When choosing pump materials, be sure tocheck the temperature limits for all wetted components.Example: FKM has a maximum limit of 176.7 C (350 F) butpolypropylene has a maximum limit of only 79 C (175 F).NOTE: Before starting disassembly, mark a line from eachliquid chamber to its corresponding air chamber. This linewill assist in proper alignment during reassembly.CAUTION: Maximum temperature limits are based uponmechanical stress only. Certain chemicals will significantlyreduce maximum safe operating temperatures. Consultengineering guide for chemical compatibility andtemperature limits.CAUTION: Verify the chemical compatibility of theprocess and cleaning fluid to the pump’s componentmaterials in the Chemical Resistance Guide (see E4).CAUTION: When removing the end cap using compressedair, the air valve end cap may come out with considerableforce. Hand protection such as a padded glove or ragshould be used to capture the end cap.CAUTION: Always wear safety glasses when operatingpump. If diaphragm rupture occurs, material being pumpedmay be forced out air exhaust.WARNING: Prevention of static sparking — If staticsparking occurs, fire or explosion could result. Pump,valves, and containers must be properly grounded whenhandling flammable fluids and whenever discharge ofstatic electricity is a hazard.NOTE: All non lube-free air-operated pumps mustbe lubricated. Wilden suggests an arctic 5 weight oil(ISO grade 15). Do not over-lubricate air supply.Over- lubrication will reduce pump performance.CAUTION: Do not exceed 8.6 bar (125 psig) airsupply pressure.NOTE: UL-listed pumps must not exceed 3.4 bar(50 psig) air supply pressure.CAUTION: Only explosion proof (NEMA 7) solenoidvalves should be used in areas where explosion proofequipment is required.WIL-10252-E-014Wilden

Section 3HOW IT WORKS — PUMPThe Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show the flowpattern through 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 as aseparationmembranebetweenthecompressed air and liquid, balancing theload and removing mechanical stress fromthe diaphragm. The compressed air movesthe diaphragm away from the center blockof the pump. The opposite diaphragm ispulled in by the shaft connected to thepressurized diaphragm. Diaphragm B is onits suction stroke; air behind the diaphragmhas been forced out to the atmospherethrough the exhaust port of the pump. Themovement of diaphragm B toward thecenter block of the pump creates a vacuumwithin chamber B. Atmospheric pressureforces fluid into the inlet manifold forcing theinlet valve ball off its seat. Liquid is free tomove past the inlet valve ball and fill theliquid chamber (see shaded area).WIL-10252-E-01FIGURE2When the pressurizeddiaphragm, diaphragm A, reaches the limit ofits discharge stroke, the air valve redirectspressurized air to the back side of diaphragmB. The pressurized air forces diaphragm Baway from the center block while pullingdiaphragm A to the center block. DiaphragmB is now on its discharge stroke. DiaphragmB forces the inlet valve ball onto its seat dueto the hydraulic forces developed in the liquidchamber and manifold of the pump. Thesesame hydraulic forces lift the discharge valveball off its seat, while the opposite dischargevalve ball is forced onto its seat, forcing fluidto flow through the pump discharge. Themovement of diaphragm A toward the centerblock of the pump creates a vacuum withinliquid chamber A. Atmospheric pressureforces fluid into the inlet manifold of thepump. The inlet valve ball is forced off its seatallowing the fluid being pumped to fill theliquid chamber.6FIGURE 3 At completion of the stroke, theair valve again redirects air to the back sideof diaphragm A, which starts diaphragm Bon its exhaust stroke. As the pump reachesits original starting point, each diaphragmhas gone through one exhaust and onedischarge stroke. This constitutes onecomplete pumping cycle. The pump maytake several cycles to completely primedepending on the conditions of theapplication.Wilden
