Installation
SYSTEM ACCESSORIES
DA pressure reducing valve (H), with a drain line
(E) running into the hydraulic return line (D).
WARNING
A fluid drain valve (M) is required in your system to help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin if you are adjusting or repairing the pump.
The fluid drain valve assists in relieving fluid pres- sure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.
Mounting Accessories
Mount the pump (A) to suit the type of installation planned. Fig. 4 on page 10 illustrates a
If you are mounting the pump on a
Filters
Be sure your hydraulic power supply is equipped with a suction filter to the hydraulic pump and a system return line filter (AA) of 10 micron size.
Carefully follow the manufacturer’s recommendations on reservoir and filter cleaning, and periodic changes of hydraulic fluid. Use only
Hydraulic Lines
The motor has a 3/4 npt(f) hydraulic oil supply fitting, and a 1” npt(f) hydraulic oil return fitting. Use a mini- mum 13 mm (1/2 in.) ID hydraulic supply line, and a minimum 16 mm (5/8 in.) ID return line.
On the hydraulic supply line (C), install the following accessories in the order shown in Fig. 4, using adapt- ers as necessary:
DA shutoff valve (U) to isolate the pump for servic- ing.
DA fluid pressure gauge (F) to monitor hydraulic oil pressure to the motor and to avoid overpressurizing the motor or displacement pump, and a pressure- and
DAn accumulator (J) to reduce the hammering effect caused by the motor reversing direction.
On the hydraulic return line (D), install the following accessories in the order shown in Fig. 4, using adapt- ers as necessary:
DA shutoff valve (V) to isolate the pump for servic- ing.
DA filter (AA) of 10 micron size.
Hydraulic Motor Drip Pan
The hydraulic motor has a drip pan to collect any leakage that may occur. Connect a 6 mm (1/4 in.) ID drain line (K) to the barbed hose fitting on the drip pan, and place the free end in a suitable container to re- ceive the drainage.
Fluid Supply Hoses
Be sure the fluid supply hose (N) is properly sized and
Fluid Line Accessories
Install the following accessories in the positions shown in Fig. 4, using adapters as necessary:
DInstall a fluid shutoff valve (P) at each gun drop, to isolate the gun and fluid accessories for servic- ing.
DInstall a fluid drain valve (M) near the pump fluid outlet, and at each gun station. The drain valves are required in your system to relieve fluid pressure in the displacement pump, hose and gun (see the WARNING at left). Drain valves at the gun stations may be mounted in the base of a fluid regulator (L), using an adapter.
DA fluid regulator (L) controls fluid pressure to the gun/valve, and dampens pressure surges.
DA gun or valve (S) dispenses the fluid. The gun shown in Fig. 4 is a high pressure dispensing gun for highly viscous fluids.
DA gun swivel (R) allows freer gun movement.
