Installation (Air-Powered Pumps)

Air Line to Motor

5.The air filter (K) removes harmful dirt and moisture from the compressed air supply.

WARNING

A bleed-type master air valve (D) is required in your system, to help reduce the risk of serious injury including splashing fluid in the eyes or on the skin, and injury from moving parts if you are adjust- ing or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump. Order Part No. 113–333.

1.The air line lubricator (N) automatically lubricates the air motor to prevent corrosion. See Fig. 2.

2.The bleed-type master air valve (M) relieves air trapped between itself and the motor, when the valve is closed. Install one valve close to the pump, downstream from the air regulator. Install a second bleed valve upstream from all other air line accessories, to isolate the accessories for servic- ing.

3.The air regulator (L) controls pump speed.

4.The pump runaway valve (P) shuts off the air to the pump if the pump speed exceeds your pre-ad- justed setting. Running a pump too fast can dam- age it.

6.The air supply line (J) must be large enough to supply the proper volume of air to the motor.

Fluid Line from Pump

WARNING

A fluid drain valve (J) is required in your system, to help reduce the risk of serious injury including splashing in the eyes or on the skin if the pump cycles unexpectedly.

Locate one valve downstream from the pump outlet and another valve downstream from the surge tank

(G). These drain valves are used to relieve fluid pressure in the pump and surge tank during shut- down.

1.The surge tank (G) reduces fluid surging to pre- vent backflow into the pump. Mounting instructions are supplied with the tank.

2.The shutoff valves (D) before and after the surge tank, and between each mix tank and the pump fluid inlet, isolate these components for servicing.

3.Be sure the supply line (C) between the pump and mix tanks is level.
