Safety Information IMPORTANT WARNING When used for toxic or aggressive fluids, the pump should always be flushed clean prior to disassembly. 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. Before maintenance or repair, shut off the compressed gas line, bleed the pressure, and disconnect the gas line from the pump.

Principle of Pump Operation 2: INSTAL & OP Gas-Operated Double Diaphragm pumps are powered by compressed gas, nitrogen or natural gas. The main directional (gas) control valve ① distributes compressed gas to an gas chamber, exerting uniform pressure over the inner surface of the diaphragm ②. At the same time, the exhausting gas ③ from behind the opposite diaphragm is directed through the gas valve assembly(s) to an exhaust port ④.
Recommended Installation Guide 1 020.064.000 Filter VENTING WARNING: This filter is equipped with a stainless steel manual drain. The port is 1/8" NPT. When draining moisture from the filter, first shut off the natural gas supply. 2 020.059.000 REGULATOR WITH GAGE PRESSURE WARNING: This regulator is to be installed at point of use with the pump. The maximum gas supply is 400psi. Full line pressure needs to be regulated below 400psi prior to the regulator installation position.
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 gas supply pressure). Gas 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 through hole in the inner diaphragm plate.
PUMPING HAZARDOUS LIQUIDS When a diaphragm fails, the pumped liquid or fumes enter the natural gas end of the pump. Fumes are exhausted into the surrounding environment. When pumping hazardous or toxic materials, the exhaust gas must be piped to an appropriate area for safe disposal. See illustration #1 at right. This pump can be submerged if the pump materials of construction are compatible with the liquid being pumped. The natural gas exhaust must be piped above the liquid level.
