Installation (Hydraulic-Powered Pumps)

Hydraulic Power Supply

CAUTION

The Hydraulic Power Supply must be kept clean at all times to avoid damage to the motor and hydraulic power supply.

1.Blow out hydraulic lines with air and flush thor- oughly before connection to the motor.

2.Plug hydraulic inlets, outlets, and line ends when disconnecting them for any reason.

1.Be sure the power supply can provide sufficient power to the motor.

2.Be sure the power supply is equipped with a suction filter to the hydraulic pump.

Hydraulic Supply to Motor

NOTE: The motor’s hydraulic inlet is 3/4 in., 37_ flare. Use a minimum 13 mm (1/2 in.) ID hydraulic supply line (L).

1.The shutoff valve (R) isolates the motor when servicing the system. See Fig. 3.

2.The hydraulic fluid pressure gauge (Q) monitors the hydraulic oil pressure to the motor. This helps avoid overpressurizing the motor or displacement pump.

3.The pressure- and temperature-compensated flow control valve (S) prevents the motor from running too fast, which can damage it.

4.The pressure reducing valve (P) which has a drain line (M) running to the return line (K), controls the hydraulic pressure to the motor.

Hydraulic Return from Motor

NOTE: The motor’s hydraulic outlet is 7/8 in., 37_ flare. Use a minimum 16 mm (5/8 in.) ID hydraulic return line (K).

1.The shutoff valve (R) isolates the motor when servicing the system.

CAUTION

To avoid damage to the pump, never use the return line shutoff valve to control the hydraulic flow. Do not install any flow control devices on the hydraulic re- turn line.

2.The 10 micron size return filter (J) removes resi- due from the hydraulic fluid to help keep the sys- tem running smoothly.

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.
