Page 6: Principle Of Pump Operation
Principle of Pump Operation Air-Operated Double Diaphragm (AODD) pumps are powered by compressed air. The main directional (air) control valve distributes ① compressed air to an air chamber, exerting uniform pressure over the inner surface of the diaphragm . At the same time, ② the exhausting air from behind the opposite diaphragm ③ is directed through the air valve assembly(s) to an exhaust port ④ (P1) Air Line As inner chamber pressure exceeds liquid chamber (P2) pressure... -
Page 7: Recommended Installation Guide
recommended Installation Guide Installation And Start-Up Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of fittings to a minimum. Do not reduce the suction line diameter. Air Supply Connect the pump air inlet to an air supply with sufficient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to insure air supply pressure does not exceed recommended limits. Air Valve Lubrication The air distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an air line lubricator set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of air the pump consumes. Consult the Performance Curve to determine air consumption. Air Line Moisture Water in the compressed air supply may cause icing or freezing of the exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can be reduced by using a point-of-use air dryer. Air Inlet And Priming To start the pump, slightly open the air shut-off valve. After the pump primes, the air valve can be opened to increase air flow as desired. If opening the valve increases cycling rate, but does not increase the rate of flow, cavitation has occurred. The valve should be closed slightly to obtain the most efficient air flow to pump flow ratio. 41-818810sm-rev0812... -
Page 8: Troubleshooting Guide
Troubleshooting Guide Symptom: Potential Cause(s): Recommendation(s): Pump Cycles Once Deadhead (system pressure meets or exceeds air Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero flow. supply pressure). (Does not apply to high pressure 2:1 units). Air valve or intermediate gaskets installed incorrectly. Install gaskets with holes properly aligned. Bent or missing actuator plunger. Remove pilot valve and inspect actuator plungers. Pump Will Not Operate Pump is over lubricated. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation. / Cycle Lack of air (line size, PSI, CFM). Check the air line size and length, compressor capacity (HP vs. CFM required). Check air distribution system. Disassemble and inspect main air distribution valve, pilot valve and pilot valve actuators. -
