Safety Information IMPORTANT WARNING Read the safety warnings and instructions in this manual before pump installation and start-up. Failure to comply with the recommendations stated in this manual could damage the pump and void factory warranty. When the pump is used for materials that tend to settle out or solidify, the pump should be flushed after each use to prevent damage. In freezing temperatures the pump should be completely drained between uses.

Principle of Pump Operation Air-Operated Double Diaphragm (AODD) pumps are powered by compressed air, nitrogen or natural gas. As inner chamber pressure (P1) exceeds liquid chamber pressure (P2), the rod ⑤ connected diaphragms shift together creating discharge on one side and suction on the opposite side. The discharged and primed liquid’s directions are controlled by the check valves (ball or flap)⑥ orientation. Air Line Discharged Fluid The pump primes as a result of the suction stroke.

Troubleshooting Guide Pump Cycles Once Pump Will Not Operate / Cycle Pump Cycles and Will Not Prime or No Flow Pump Cycles Running Sluggish / Stalling, Flow Unsatisfactory Product Leaking Through Exhaust Premature Diaphragm Failure Unbalanced Cycling Potential Cause(s): Deadhead (system pressure meets or exceeds air supply pressure). Air valve or intermediate gaskets installed incorrectly. Bent or missing actuator plunger. Pump is over lubricated. Lack of air (line size, PSI, CFM).

Diaphragm Servicing Step 1: With manifolds and outer chambers removed, remove diaphragm assemblies from diaphragm rod. DO NOT use a pipe wrench or similar tool to remove assembly from rod. Flaws in the rod surface may damage bearings and seal. Soft jaws in a vise are recommended to prevent diaphragm rod damage. Step 1.A: NOTE: Not all inner diaphragm plates are threaded. Some models utilize a through hole in the inner diaphragm plate.
