Principle of Pump Operation Air-Operated Double Diaphragm (AODD) pumps are powered by compressed air or nitrogen. 2: INSTAL & OP The main directional (air) control valve ① distributes compressed air to an air chamber, exerting uniform pressure over the inner surface of the diaphragm ②. At the same time, the exhausting air ③ from behind the opposite diaphragm is directed through the air valve assembly(s) to an exhaust port ④.
Recommended Installation Guide Available Accessories: 1. Surge Suppressor 2. Filter/Regulator 3.
Troubleshooting Guide Symptom: Pump Cycles Once 2: INSTAL & OP 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.

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 though hole in the inner diaphragm plate.
