System Accessories
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 pressure 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 illustrates a wall-mounted system.
Pump dimensions and the mounting hole layout are
shown on pages 44 and 45.
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 Graco-approved hydraulic
oil. Order Part No. 169236, 19 liter (5 gal.) or Part No.
207428, 3.8 liter (1 gal.). Do not substitute a lower
grade oil or one with a lower flash point.
Hydraulic Lines
The motor has a 3/4 npt(f) hydraulic oil supply fitting,
and a 1 in. npt(f) hydraulic oil return fitting. Use a
minimum 13 mm (1/2 in.) ID hydraulic supply line, and
a minimum 22 mm (7/8 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:
D A shutoff valve (U) isolates the pump for service.
D A 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 temperature compensated flow control
valve (G) to prevent the motor from running too
fast and possibly damaging itself.
D A pressure reducing valve (H), with a drain line
(E) run directly to the hydraulic return line (D).
Installation
(HYDRAULIC-POWERED PUMPS)
D An 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:
D A shutoff valve (V) isolates the pump for service.
D A filter (AA) of 10 micron size.
Hydraulic Motor Drip Pan
The hydraulic motor has a drip pan to collect any
leakage. Connect a 6 mm (1/4 in.) ID drain line (K) to
the barbed fitting on the drip pan, and place the free
end in a container to receive the drainage.
Fluid Supply Hoses
Be sure all fluid supply hoses (N and P) are properly
sized and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have
spring guards on both ends. Use a whip hose (P) and
a swivel (R) between the main fluid hose (N) and the
gun/valve (S) to allow for easier gun/valve movement.
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 4, using adapters as necessary:
D A fluid filter (L) with a 60 mesh (250 micron)
stainless steel element, to filter particles from the
fluid as it leaves the pump. It includes a fluid drain
valve (M), which is required in your system to
relieve fluid pressure in the hose and gun (see the
WARNING at left).
D A gun or valve (S) dispenses the fluid. The gun
shown in Fig. 4 is an airless spray gun for light to
medium viscosity fluids.
D A gun swivel (R) allows for easier gun movement.
D A suction kit (T) allows the pump to draw fluid
from a 200 liter (55 gallon) drum.
