Installation (Air–Powered Pumps)
D A pump runaway valve (V) senses when the
pump is running too fast and automatically shuts off
the air to the motor. A pump which runs too fast can
be seriously damaged. Locate in the position
shown.
WARNING
A main air bleed valve (C), pump air bleed valve
(E), and fluid drain valve (M) are required. These
accessories help reduce the risk of serious injury,
including fluid injection and splashing of fluid in the
eyes or on the skin, and injury from moving parts if
you are adjusting or repairing the pump.
D An air manifold (G) has a swivel air inlet. It
mounts to a ram, and has ports for connecting lines
to air accessories, such as the ram air regulator
(T) and ram director valve (U).
The main air bleed valve (C) shuts off the air to the
pump and ram. The pump air bleed valve (E)
relieves air trapped between this valve and the
pump after the air is shut off. Trapped air can
cause the pump to cycle unexpectedly. Locate the
valve close to the pump. Order Part No. 107141.
D An air line filter (J) removes harmful dirt and
moisture from the compressed air supply. Also,
install a drain valve (W) at the bottom of each air
line drop, to drain off moisture.
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. Order Part No. 210658.
D An air shutoff valve (K) isolates the air line acces-
sories for servicing. Locate upstream from all other
air line accessories.
Fluid Line Accessories
Air Line Accessories

in Figs. 3 and 4, using adapters as necessary:
Install the following accessories in the order shown in
Fig. 3, using adapters as necessary:
D Install a fluid shutoff valve (P) at each gun/valve
drop, to isolate the gun/valve and fluid accessories
for servicing.
D An air line lubricator (D) provides automatic air
motor lubrication. Locate in the position shown.
D A main air bleed valve (C) is required in your
system to shut off the air supply to the pump and
ram (see the WARNING above). When closed, the
valve will bleed off all air in the ram and pump, and
the ram will slowly lower. Be sure the valve is easily
accessible from the pump, and is located upstream
from the air manifold (G).
D Install a fluid drain valve (M) near the pump fluid
outlet, and at each gun/valve station. The drain
valves are required in your system to relieve fluid
pressure in the displacement pump, hose and
gun/valve (see the WARNING at left). Drain valves
at the gun/valve stations may be mounted in the
base of a fluid regulator (L), using an adapter.
D A pump air bleed valve (E) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed (see the WARNING
at left). Be sure the bleed valve is easily accessible
from the pump, and is located downstream from
the air regulator.
D A fluid regulator (L) controls fluid pressure to the
gun/valve, and dampens pressure surges.
D A gun or dispense valve (S) dispenses the fluid.
The gun shown in Fig. 3 is a high pressure dispens-
ing gun for highly viscous fluids.
D An air regulator (F) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the pump air bleed valve.
D A gun/valve swivel (R) allows freer gun/valve
movement.

flow capacity as the oil supply line. Otherwise, back
pressure on the hydraulic motor piston will slow down
the motor and the fluid displacement pump, resulting in
a loss of pump performance.
1. Blow out hydraulic lines with air and flush thor-
oughly before connection to the motor.
On the hydraulic oil supply line (P), install a shutoff
valve (G) to isolate the system for servicing; a fluid
pressure gauge (H) to monitor hydraulic oil pressure to
the motor and avoid overpressurizing the motor or
displacement pump; a pressure- and temperature-
compensated flow control valve (J) to prevent the
motor from running too fast; a pressure reducing valve
(K) with a drain line (L) running directly into the hydrau-
lic return line (Q); and an accumulator (N) to reduce
the hammering effect caused by the motor reversing
direction.
2. Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.
Always plug the hydraulic inlets, outlets and lines when
disconnecting them for any reason to avoid introducing
dirt and other contaminants into the system.
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.
On the hydraulic return line (Q), install a shutoff valve
(M) for isolating the motor for servicing.

priming piston (21) during operation and
whenever the pump is charged with air.
The priming piston extends beyond the intake
housing (19) to pull material into the pump and can
amputate a hand or finger caught between it and
the intake housing. Follow the Pressure Relief
Procedure on page 12, before checking, clearing,
or cleaning the priming piston.
5. Slowly open the air regulator until the pump starts.
6. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
7. Release the gun/valve trigger and lock the trigger
safety. The pump should stall against pressure.
8. If the pump fails to prime properly, open the
bleeder valve plug (20) slightly. Use the bleed hole,
on the underside of the valve body (29), as a
priming valve until the fluid appears at the hole.
See Fig. 5. Close the plug.
WARNING
SKIN INJECTION HAZARD
To reduce the risk of fluid injection, do not use
your hand or fingers to cover the bleed hole on the
underside of the bleeder valve body (29) when
priming the pump. Use a crescent wrench to open
and close the bleeder plug (20). Keep your hands
away from the bleed hole.
NOTE: When changing fluid containers with the hose
and gun/valve already primed, open the bleeder valve
plug (20), to help prime the pump and vent air before it
enters the hose. Close the plug when all air is elimi-
nated.
9. With the pump and lines primed, and with ade-
quate air pressure and volume supplied, the pump
will start and stop as you open and close the
gun/valve. In a circulating system, the pump will
speed up or slow down on demand, until the air
supply is shut off.
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 con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
10. Use the air regulator (F) to control the pump speed
and the fluid pressure. Always use the lowest air
pressure necessary to get the desired results.
Higher pressures cause premature tip/nozzle and
pump wear.
