Warranty Each and every product manufactured by Wilden is built to meet the highest standards of quality. Every pump is functionally tested to ensure integrity of operation. Wilden warrants that pumps, accessories and parts manufactured or supplied by it to be free from defects in material and workmanship for a period of five (5) years from date of installation or six (6) years from date of manufacture, whichever comes first.
*4°C to 149°C (40°F to 300°F) - 13 mm (1/2") and 25 mm (1") models only. NOTE: Some PTFE-fitted pumps come standard from the NOTE: Not all materials are available for all models. See “Wilden factory with expanded PTFE gaskets installed in the Pump Designation System” material options for your pump.
HOW IT WORKS – AIR-OPERATED DOUBLE-DIAPHRAGM PUMP The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow pattern through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.

P4 Clamped Metal SECTION 5 SUCTION LIFT CAPABILITY P4 METAL SUCTION- LIFT CAPABILITY Suction-lift curves are calibrated for pumps operating at 305 m (1,000') above sea level. This chart is meant to be a guide only. There are many variables that can affect your pump's operating characteristics.
The suction pipe size should be at least equal to or larger than the elbows, bends and fittings should be avoided. Pipe sizes should diameter size of the suction inlet on your Wilden pump. The suction be selected to keep friction losses within practical limits. All piping hose must be a non-collapsible, reinforced type because these should be supported independently of the pump.

Frequency of use, line pressure, viscosity and abrasiveness of process fluid all affect the parts life of a Wilden Operation pump. Periodic inspections have been found to offer the best means The Pro-Flo pumps are pre-lubricated and do not require in- line for preventing unscheduled pump downtime.
P4 Clamped Metal SUGGESTED INSTALLATION, OPERATION, MAINTENANCE AND TROUBLESHOOTING Troubleshooting Pump air valve freezes. Pump will not run or runs slowly. Check for excessive moisture in the compressed air. Remove plug from pilot spool exhaust. Either install a dryer or a hot air generator for compressed Ensure that the air inlet pressure is at least 0.4 bar (5 psig)

P4 Clamped Metal GASKET KIT INSTALLATION Carefully prepare sealing surfaces by removing all debris and foreign matter from diaphragm bead and all mating surfaces. If necessary, smooth or deburr all sealing surfaces. Mating surfaces must be properly aligned in order to ensure positive sealing characteristics.
