SERVICE AND OPERATING MANUAL Original Instructions ET1½ - SM CONTAINMENT DUTY Type 1 PRINCIPLE OF OPERATION This ball check valve pump is powered by compressed air and is a 1:1 pressure ratio design. It alternately pressurizes the inner side of one diaphragm chamber, while simultaneously exhausting the other inner chamber. This causes the diaphragms, which are connected by a common rod, to move endwise.
PAGE 5
AIR SUPPLY Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump air inlet (see Fig. 1) to an air supply of sufficient capacity and pressure required for desired performance. When the air line is solid piping, use a short length of flexible hose (not less than ¾" [19mm] in diameter) between pump and piping to eliminate strain to pipes. AIR INLET & PRIMING For start-up, open an air valve approximately ½ to ¾ turn.

preventive maintenance schedule to do so on a regular basis. This practice should include cleaning the spool and sleeve components with a safety solvent or equivalent, inspecting for signs of wear or damage, and replacing worn components. To re-install the sleeve and spool set, lightly lubricate the o-rings on the sleeve with an o-ring assembly lubricant or lightweight oil (such as 10 wt. air line lubricant). Press the set into the valve body easily, without shearing the o-rings.
PAGE 7
CHECK VALVE SERVICING Need for inspection or service is usually indicated by poor priming, unstable cycling, reduced performance or the pump’s cycling but not pumping. Remove the six flange bolts securing the inlet and outlet flanges to the manifold. Inspect the surfaces of both check valve and seat for wear or damage that could prevent proper sealing. If pump is to prime properly, valves must seat air tight (see Fig. 6).
PAGE 8
SERVICE INSTRUCTIONS: TROUBLE SHOOTING 1. Pump will not cycle A. Check to make sure the unit has enough pressure to operate and that the air inlet valve is open. B. Check the discharge line to insure that the discharge line is neither closed nor blocked. C. If the spool in the air distribution valve is not shifting, check the main spool. It must slide freely. D. Excessive air leakage in the pump can prevent cycling. This condition will be evident.

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 air line, bleed the pressure, and disconnect the air line from the pump.
