4 225 F CAUTION: When choosing pump materials, be sure to check the temperature limits for all wetted compo-nents. Example: Viton has a maximum limit of C (350 F) but polypropylene has a maximum limit of only 79 C (175 F) .CAUTION: Maximum temperature limits are based upon mechanical stress only. Certain chemicals will significantly reduce maximum safe operating tempera-tures. Consult engineering guide for chemical compat-ibility and temperature : Always wear safety glasses when operat-ing pump.

5 If diaphragm rupture occurs, material being pumped may be forced out air : Prevention of static sparking If static sparking occurs, fire or explosion could result. Pump, valves, and containers must be properly grounded when handling flammable fluids and whenever dis-charge of static electricity is a hazard. CAUTION: Do not exceed bar (125 psig) air supply : P2R Pumps are made of virgin plastic and are not UV stabilized. Direct sunlight for prolonged periods can cause deterioration of : 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.

6 Disconnect all intake, discharge and air lines. Drain the pump by turning it upside down and allowing any fluid to flow into a suitable container. CAUTION: Blow out air line for 10 to 20 seconds before attaching to pump to make sure all pipe line debris is clear. Use an in-line air filter. A 5 (micron) air filter is : Tighten clamp bands and retainers prior to installation. Fittings may loosen during : When installing PTFE diaphragms, it is impor-tant to tighten outer pistons simultaneously (turning in opposite directions) to ensure tight : Before starting disassembly, mark a line from each liquid chamber to its corresponding air chamber.

7 This line will assist in proper alignment during : Verify the chemical compatibility of the pro-cess and cleaning fluid to the pump s component mate-rials in the Chemical Resistance Guide (see RBG E4).CAUTION: When removing the end cap using com-pressed air, the air valve end cap may come out with considerable force. Hand protection such as a padded glove or rag should be used to capture the end cap. CAUTION: P2R PTFE-fitted Pumps come standard from the factory with expanded PTFE gaskets.

8 (See Gasket Kit Installation in Section CAUTION: Do not over-tighten the air inlet reducer bushing. Too much torque on the reducer bushing may damage the air valve muffler plate. Do not exceed N m (8in-lbs).NOTE: When reinstalling the outer pistons, apply two (2) drops of Loctite 246 to the shaft internal threads before the diaphragm : MOST ELASTOMERIC MATERIALS USE COLORED DOTS FOR is registered trademarks of DuPont Dow PUMP & ENGINEERING, LLCWIL-10150-E-05 SECTION 2 Wilden PUMP DESIGNATION SYSTEM*O-RINGS NOT ORIGINAL PLASTIC25 mm (1") PumpMaximum Flow Rate.)
