CAUTION
It is very important to keep the hydraulic supply
system clean at all times. Be sure that all hydraulic
fluid lines are absolutely clean. Blow out the lines
with air and flush thoroughly with solvent before
connecting to the hydraulic motor, to avoid introducing harmful contaminants into the motor.
Do not exceed 3 gpm (11.4 liter/min) hydraulic oil
volume to the motor, to avoid pump stalling.
For optimum pump performance, keep the temperature of the hydraulic oil below 130_F (54_C).
The hydraulic motor has a 3/4–16(m) 37_ flared hydraulic oil supply fitting, and a 7/8–14(m) 37_ flared
hydraulic oil return fitting. Use a minimum 1/2 in. (13
mm) ID hydraulic supply line, and a minimum 5/8 in.

Fig. 2, using adapters as necessary.
WARNING
A fluid drain valve (L) is required in your system to
help reduce the risk of serious injury, including
splashing of fluid in the eyes or on the skin.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and dispense valve. Triggering the valve to relieve pressure may not be sufficient.
D The fluid drain valve (L) is required in your system to relieve fluid pressure in the hose and dispense valve (see the WARNING above).
D Connect a suction tube kit (N) to the pump’s
1–1/2” npt(f) fluid inlet.

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or dispensing
accidentally. To reduce the risk of an injury from
accidental spray from the dispense valve, splashing fluid, or moving parts, follow the Pressure
Relief Procedure whenever you:
are instructed to relieve the pressure,
stop dispensing,
check or service any of the system equipment,
or install or clean the dispense valve nozzle.
Check the tightness of the packing nut/wet-cup (U)
periodically. The nut should be tight enough to prevent
leakage. Torque the nut to 20–24 ft-lb (27–33 N.m); do
not overtighten or you may damage the packings.
Relieve pressure before adjusting the nut. See Fig. 3.
Fill the packing nut/wet-cup 1/2 full with a compatible
solvent. Keep the cup filled at all times to help prevent
the fluid you are pumping from drying on the exposed
displacement rod and damaging the throat packings.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a
compatible solvent. See Flushing on page 10.
1. Lock the dispense valve trigger safety.
2. Shut off the hydraulic power supply.
3. Close the supply line shutoff valve (P), then the
return line shutoff valve (R).
4. Unlock the dispense valve trigger safety.
5. Hold a metal part of the dispense valve firmly to
the side of a grounded metal pail, and trigger the
valve to relieve pressure.
6. Lock the dispense valve trigger safety.
7. Open the drain valve (L, required in your system),
having a container ready to catch the drainage.
8. Leave the drain valve open until you are ready to
dispense again.
U
If you suspect that the dispense nozzle or hose is
completely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the hose end coupling and relieve pressure
gradually, then loosen completely. Now clear the
nozzle or hose.
Packing Nut
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure above.

Operation
Prime the Pump
1. See Fig. 2. Connect the suction kit (N) to the
pump’s fluid inlet, and place the tube into the fluid
supply.
2. Check the hydraulic fluid level before each use,
and add fluid as necessary.
3. Close the supply line shutoff valve (P) and the
return line shutoff valve (R).
4. Start the hydraulic power supply.
5. Hold a metal part of the dispense valve (if used)
firmly to the side of a grounded metal pail and hold
the trigger open.
6. Open the return line shutoff valve (R) first, then
slowly open the supply line shutoff valve (P).
7. Run the pump slowly until all air is pushed out and
the system is fully primed. Always use the lowest
pressure necessary to get the desired results.
Higher pressures cause premature pump wear.
8. Release the dispense valve trigger and lock the
trigger safety. With adequate hydraulic volume
supplied to the motor, the pump will start and stop
as you open and close the dispense valve.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
9. Relieve the pressure. Install the nozzle in the
dispense valve, as explained in the dispense valve
manual.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause component rupture and serious injury, never
exceed 1000 psi (70 bar) maximum hydraulic input
pressure or 3 gpm (11.4 liter/min) hydraulic input to
the pump, or 250 psi (17 bar) maximum fluid
working pressure (see Technical Data on page ).
To prevent overpressurizing the hydraulic motor or
its seals, always shut off the supply line valve (P)
first, then shut off the return line valve (R).
CAUTION
Do not allow the hydraulic oil temperature to exceed
130F (54C). The pump seals will wear faster and
leakage may occur if the pump is operated at higher
oil temperatures.
10. Use the fluid pressure gauge (F) and pressurereducing valve (H) to control pump outlet pressure
and pump speed. Always use the lowest hydraulic
flow and pressure necessary to get the desired
results. Higher pressure causes premature pump
wear.
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.

Maintenance
Shutdown and Care of 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.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the exposed displacement rod and damaging the throat
packings. Relieve the pressure.
CAUTION
Never leave water or water-base fluid in the pump
overnight. If you are pumping water-base fluid, flush
with water first, then with a rust inhibitor such as
mineral spirits. Relieve the pressure, but leave the
rust inhibitor in the pump to protect the parts from
corrosion.
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 flush the pump before the fluid dries on the
displacement rod. See Flushing below.
