4 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. 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.

5 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. 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.

6 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. 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).

7 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. (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.)
