Section 1Precautions - Read First!WARNING: Always wear safety glasses whenoperating a pump to avoid eye injury. If diaphragmrupture occurs, material being pumped maybe forcedout of the air exhaust.CAUTION: Do not exceed 82 C (180 F) airinlet temperature for all models.CAUTION: Thoroughly flush pumps before installingthem into process lines. Clean and/or sanitize FDAand USDA- approved pumps before using them.CAUTION: Do not apply compressed air to the exhaustport – pump will not function.CAUTION: Do not over-lubricate air supply– excess lubrication willreduce pump performance. Pump is pre-lubed.TEMPERATURE LIMITS:AcetalBuna-NGeolast NeopreneNordel EPDMNylonPFAPolypropylenePolyurethanePVDFSaniflex SIPD PTFE with EPDM-backedSIPD PTFE with Neoprene-backedPTFE1FKMWil-Flex 14 C–29 C to 82 C–12 C to 82 C–40 C to 82 C–18 C to 93 C–51 C to 138 C–18 C to 93 C–7 C to 107 C0 C to 79 C–12 C to 66 C–12 C to 107 C–29 C to 104 C4 C to 137 C4 C to 93 C4 C to 104 C–40 C to 177 C–40 C to 107 C–20 F to 180 F10 F to 180 F–40 F to 180 F0 F to 200 F–60 F to 280 F0 F to 200 F45 F to 225 F32 F to 175 F10 F to 150 F10 F to 225 F–20 F to 220 F40 F to 280 F40 F to 200 F40 F to 220 F–40 F to 350 F–40 F to 225 Fto 149 C (40 F to 300 F) - 13 mm (1/2") and 25 mm (1") models only.NOTE: Not all materials are available for all models. See "WildenPump Designation System on page 5 for material options for yourpump.CAUTION: Before attempting any maintenance or repair,disconnect the compressed air line to the pump and allow allair pressure to bleed from the pump. Disconnect all intake,discharge, and air lines. Drain the pump by turning it upsidedown and allowing any fluid to flow into a suitable container.Be aware of any hazardous effects of contact with yourprocess fluid.CAUTION: Before attaching the air line to the pump,blow out the air line for 10 to 20 seconds to make sureall pipeline debris is clear. Use an in-line air filter. A 5µ(micron) air filter is recommended.CAUTION: Pro-Flo pumps cannot be used insubmersible applications.CAUTION: Before installation, tighten all hardware.NOTE: Materials of construction and elastomer materialhave an effect on suction lift parameters. Please referto "Performance " on page 8 for specifics.NOTE: When installing PTFE diaphragms, it isimportant to tighten outer pistons simultaneously(turning in opposite directions) to ensure tight fit. (See"Maximum Torque Specifications" on page 21.)CAUTION: When choosing pump materials, be sure to check thetemperature limits for all wetted components.Example: FKM has a maximum limit of 177 C (350 F), butpolypropylene has a maximum limit of only 79 C (175 F).CAUTION: Maximum temperature limits are based on mechanicalstress only. Certain chemicals will reduce maximum safe operatingtemperatures significantly. Consult the Chemical Resistance Guidefor chemical compatibility and temperature limits.NOTE: Some PTFE-fitted pumps come standardfrom the factory with expanded PTFE gaskets installedin the diaphragm bead of the liquid chamber. PTFEgaskets cannot be re-used.NOTE: In the event of a power failure, close the shut-offvalve if you do not want the pump to restart when thepower returns.WARNING: Prevent Static Sparking. If static sparking occurs, fireor explosion could result. Pump, valves and containers must begrounded to a proper grounding point when handling flammablefluids and whenever discharge of static electricity is a hazard.CAUTION: All Wilden pumps are capable of passing solids. Use astrainer on the pump intake to ensure that the pump's rated solidscapacity is not exceeded.CAUTION: Do not exceed 8.6 bar (125 psig) air supply pressure.CAUTION: The process fluid and cleaning fluids must be compatiblechemically with all wetted pump components.WIL-10184-E-024Wilden

Section 3HOW IT WORKS — PUMPThe Wilden diaphragm pump is an air-operated, placement, self-priming pump. These drawings show the 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 as aseparationmembrane between thecompressed 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 forcingthe inlet valve ball off its seat. Liquid is freeto move past the inlet valve ball and fill theliquid chamber (see shaded area).FIGURE 2 When the pressurizeddiaphragm, diaphragm A, reaches the limitof its discharge stroke, the air valveredirects pressurized air to the back side ofdiaphragm B. The pressurized air forcesdiaphragm B away from the center blockwhile pulling diaphragm A to the centerblock. Diaphragm B is now on its dischargestroke. Diaphragm B forces the inlet valveball onto its seat due to the hydraulic forcesdeveloped in the liquid chamber and manifold of the pump. These same hydraulicforces lift the discharge valve ball off itsseat, while the opposite discharge valveball is forced onto its seat, forcing fluid toflow through the pump discharge. Themovement of diaphragm A toward thecenter block of the pump creates a vacuumwithin liquid chamber A. Atmosphericpressure forces fluid into the inlet manifoldof the pump. The inlet valve ball is forcedoff its seat allowing the fluid being pumpedto fill the liquid chamber.FIGURE 3 At completion of the stroke, theair valve again redirects air to the backside of diaphragm A, which startsdiaphragm B on its exhaust stroke. As thepump reaches its original starting point,each diaphragm has gone through oneexhaust and one discharge stroke. Thisconstitutes one complete pumping cycle.The pump may take several cycles tocompletely 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 heartof the system is the air valve spool and air valve. This valvedesign incorporates an unbalanced spool. The smaller end ofthe spool is pressurized continuously, while the large end isalternately pressurized then exhausted to move the spool. Thespool directs pressurized air to one air chamber whileexhausting the other. The air causes the main shaft/diaphragmassembly to shift to one side — discharging liquid on that sideand pulling liquid in on the other side. When the shaft reachesthe end of its stroke, the inner piston actuates the pilot spool,which pressurizes and exhausts the large end of the air valvespool. The repositioning of the air valve spool routes the air tothe other air chamber.WIL-10184-E-026Wilden
