Section 1CAUTIONSREAD FIRST!CAUTION: Do not apply compressed air to the exhaust port pump will not function. CAUTION: Do not over-lubricate air supply excess lubrication will reduce pump performance. Pump is pre-lubed. TEMPERATURE LIMITS: Neoprene 17.7C to 93.3C Buna-N 12.2C to 82.2C EPDM 51.1C to 137.8C 40C to 176.7C Viton Wil-Flex 40C to 107.2C Saniex 28.9C to 104.4C Polyurethane 12.2C to 65.6C CAUTION: Pumps should be thoroughly ushed before installing into process lines. FDA and USDA approved pumps should be cleaned and/ or sanitized before being used. CAUTION: Always wear safety glasses when operating pump. If diaphragm rupture occurs, material being pumped may be forced out air exhaust. CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump should be disconnected and all air pressure allowed to bleed from pump. Disconnect all intake, discharge and air lines. Drain the pump by turning it upside down and allowing any uid to ow into a suitable container. CAUTION: Blow out air line for 10 to 20 seconds before attaching to pump to make sure all pipeline debris is clear. Use an in-line air lter. A 5 (micron) air lter is recommended. NOTE: When installing PTFE diaphragms, it is important to tighten outer pistons simultaneously (turning in opposite directions) to ensure tight t. (See torque specications in Section 7.) NOTE: Cast Iron PTFE-tted pumps come standard from the factory with expanded PTFE gaskets installed in the diaphragm bead of the liquid chamber. PTFE gaskets cannot be re-used. Consult PS-TG for installation instructions during reassembly. NOTE: Before starting disassembly, mark a line from each liquid chamber to its corresponding air chamber. This line will assist in proper alignment during reassembly. CAUTION: Pro-Flo pumps cannot be used in submersible applications. Pro-Flo X is available in both submersible and non-submersible options. Do not use non-submersible Pro-Flo X models in submersible applications. Turbo-Flo pumps can be used in submersible applications. CAUTION: Tighten all hardware prior to installation.

CAUTION: When choosing pump materials, be sure to check the temperature limits for all wetted components. Example: Viton has a maximum limit of 176.7C (350F) but polypropylene has a maximum limit of only 79C (175F). CAUTION: Maximum temperature limits are based upon mechanical stress only. Certain chemicals will signicantly reduce maximum safe operating temperatures. Consult Chemical Resistance Guide (E4) for chemical compatibility and temperature limits. WARNING: Prevention of static sparking If static sparking occurs, re or explosion could result. Pump, valves, and containers must be grounded to a proper grounding point when handling ammable uids and whenever discharge of static electricity is a hazard. CAUTION: Do not exceed 8.6 bar (125 psig) air supply pressure. CAUTION: The process uid and cleaning uids must be chemically compatible with all wetted pump components (see E4). CAUTION: Do not exceed 82C (180F) air inlet temperature for Pro-Flo X models.

Section 3HOW IT WORKSPUMPThe Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show ow pattern through the pump upon its initial stroke. It is assumed the pump has no uid in it prior to its initial stroke.

FIGURE 1 The air valve directs pressurized air to the back side of diaphragm A. The compressed air is applied directly to the liquid column separated by elastomeric diaphragms. The diaphragm acts as a separation membrane between the compressed air and liquid, balancing the load and removing mechanical stress from the diaphragm. The compressed air moves the diaphragm away from the center of the pump. The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm. Diaphragm B is on its suction stroke; air behind the diaphragm has been forced out to atmosphere through the exhaust port of the pump. The movement of diaphragm B toward the center of the pump creates a vacuum within chamber B. Atmospheric pressure forces uid into the inlet manifold forcing the inlet valve ball off its seat. Liquid is free to move past the inlet valve ball and ll the liquid chamber (see shaded area).

FIGURE 2 When the pressurized diaphragm, diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurized air to the back side of diaphragm B. The pressurized air forces diaphragm B away
