Installation
Mount the pump to suit the type of installation planned.
Pump dimensions and mounting hole layout are shown
on page 14.
CAUTION
The hydraulic supply system must be kept clean at
all times to avoid damage to the motor and hydraulic
power supply. Blow out all hydraulic lines with air and
flush thoroughly with compatible solvent before
connecting the lines to the motor.
Always plug the hydraulic inlets, outlets, and lines
when disconnecting them for any reason, to avoid
introducing dirt and other contaminants into the sys-
tem.
Filters
Be sure that your hydraulic power supply is equipped
with a suction filter to the hydraulic pump and a system
return line filter 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.
Hydraulic Lines
Connect a 3/4 in. minimum ID hydraulic supply line (L)
to the 3.4 npt inlet of the hydraulic motor. See the
Typical Installation on page 7. Connect a 1 in. mini-
mum ID return line (D) to the 1” npt return port on the
hydraulic motor.
On the hydraulic supply side (C), install the following
accessories shown in Fig. 2, using adapters as neces-
sary.
DA shutoff valve (E) isolates the pump for service.
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 temperature-compensated flow control
valve (G) to prevent the motor from running too
fast and possibly damaging itself.
DA pressure reducing valve (H), with a drain
line (K) running directly to the hydraulic return
line (D).
DAn accumulator (J) to reduce the hammering
effect caused by the motor reversing direction.
DA shutoff valve (E) isolates the pump for service.
CAUTION
Do not exceed 10 gpm (37.8 liter/minute) volume to
avoid pump stalling.
Drip Pan
The hydraulic motor is equipped with a drip pan to
collect any leakage that might occur. connect a 1/4 in.
ID drain hose (Q) to the barbed hose fitting on the drip
pan.
Drain Valve
Install a high pressure fluid drain valve (B) near the
pump fluid outlet to relieve fluid pressure in the dis-
placement pump and hose during shutdown.
WARNING
The fluid drain valve (B) is required in your system
to help reduce the risk of serious bodily injury,
including fluid injection and splashing in the eyes or
on the skin if you are adjusting or repairing any part
of the system. Triggering the gun to relieve pres-
sure may not be sufficient.
Fluid Supply Lines
Connect a grounded fluid supply line to the 1–1/2” npt
fluid outlet on the displacement pump. Attach a fluid
supply line to the 2” npt pump fluid intake.
If you are pumping through a long hose, or if the fluid
being pumped is compressible, giving an accumulator
effect, install a check valve at the pump outlet. Be sure
that the check valve selected is capable of handling
the flow and pressure developed in your system.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause seri-
ous injury. To reduce the risk of an injury
from injection, splashing fluid, or moving parts, fol-
low the Pressure Relief Procedure whenever you
DAre instructed to relieve the pressure
DStop spraying/dispensing
DCheck or service any of the system equipment
DInstall or clean the spray tips/nozzles
1. Engage the safety latch.
2. Shut off the power supply to the hydraulic motor.
3. Disengage the gun safety latch.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail. Trigger to relieve pressure.
5. Open the fluid drain valve (required in your sys-
tem) having a container ready to catch the drain-
age. Leave the drain valve open until you are
ready to spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely, then clear
the tip or hose.
CAUTION
When shutting down the hydraulic system, always
shut off the hydraulic supply line shutoff valve (S)
first, and then the return line shutoff valve (E). This
is to prevent overpressurizing the motor or its seals.
When starting the hydraulic system, open the return
line shutoff valve first.
Flushing the Pump
Flush the pump before using it for the first time to
remove the lightweight oil which is left in the pump
after factory testing to protect it from corrosion. Be
sure the solvent used is compatible with the fluid to be
sprayed, and with the wetted parts of the pump. Refer
to the Technical Data in the separate displacement
pump manual for the wetted parts. Flush until clean
solvent comes from the gun. In a circulating system,
flush long enough to clean the entire system.

Operation
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause compo-
nent rupture and serious injury, never
exceed the specified Maximum Hydraulic Input
Pressure to the pump (see the Technical Data on
page 15).
To prevent overpressurizing the hydraulic motor or
its seals, always shut off the supply line valve (S)
first, then shut off the return line valve (E).
Starting and Adjusting the Pump
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
NOTE: If the pump is not immersed in fluid, fill the
wet-cup (P) 1/3 full with Graco Throat Seal Liquid
(TSL) or a compatible solvent, to prevent fluid from
drying on the displacement rod and damaging the
pump packings. Refer to the Typical Installation on
page 7. Check the tightness of the packing nut/wet-
cup weekly. Before adjusting, relieve the pressure.
The nut should be tight enough to prevent leakage, but
no tighter.
Check the hydraulic fluid level, and add fluid as neces-
sary to the fill lines, before each use. Turn on the
hydraulic power supply. Open the return line shutoff
valve (E). Slowly open the hydraulic supply shutoff
valve (S). Run the pump slowly until all air is pushed
out of the lines and fluid is flowing smoothly. Close the
spray gun; the pump will stall. Use the lowest pressure
possible to get the desired results. Higher pressures
will cause premature tip and pump wear.
NOTE: In a direct supply system, the pump starts and
stops automatically when the spray gun is opened and
closed. In a circulating system, the pump runs continu-
ously, speeding up or slowing down as the spray gun is
opened or closed, until the hydraulic power supply is
turned off.
CAUTION
Never allow the hydraulic oil temperature to exceed
130_F (54_C). The pump seals will wear faster and
leaking may occur at higher temperatures.
WARNING
To reduce the risk of overpressurizing the system,
always follow these precautions:
Never exceed 1500 psi (10.3 MPa, 103 bar), or
10 gpm (37.8 liter/min) hydraulic input to the motor.
Never exceed 1000 psi (7 MPa, 69 bar) maximum
pump outlet pressure.
Check Valve Adjustment
The fluid piston and intake valve are factory set for
high-volume pumping of heavy, spray-viscosity fluids.
To adjust the check valves, refer to the operation
section in the separate displacement pump manual.

10 307160
Maintenance
Carefully monitor your fluid supply. If your pump us
running too fast, or accelerates quickly, it is probably
out of fluid. Shut off the hydraulic power supply imme-
diately to prevent damage to the pump. If the fluid
supply is empty, and air has entered the fluid lines, be
sure to prime the pump again before regular operation.
Flush the pump frequently enough to prevent the fluid
from drying or settling in the pump and hoses to pre-
vent costly damage. Use a compatible solvent. Refer
to the Technical Data in the separate displacement
pump manual for a list of the wetted parts.
If you are pumping water-base fluid, first flush with
water and then with a compatible solvent.
Corrosion Protection
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
CAUTION
To help prevent corrosion of the pump, never leave
the pump filled with water or water-base fluids, or air
during non-use. After flushing, flush the pump again
with a compatible solvent, such as mineral spirits,
relieve the pressure, and leave a coating of solvent
in the pump and hoses..
Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Always stop the pump with the displacement rod in the
down position. This prevents fluid from drying on the
displacement rod and damaging the packings when
the pump is restarted. Relieve the pressure whenever
you shut off the pump.
