SYSTEM ACCESSORIES
WARNING
A bleed-type master air valve (E) and a fluid drain
valve (M) are required in your system. 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.
The bleed-type master air valve 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.
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.
Air and Fluid Hoses
Be sure all air hoses (H) and fluid hoses (N) are properly sized and pressure-rated for your system. Use
only electrically conductive hoses. Fluid hoses must
have spring guards on both ends.
A bleed-type master air 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 above). Be sure the bleed valve is
easily accessible from the pump, and is located
downstream from the air regulator.
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 bleed-type master air valve.
A pump runaway valve (C) 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.
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).
An air line filter (J) removes harmful dirt and
moisture from the compressed air supply.
A second bleed-type air valve (K) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Mounting Accessories
WARNING
For Model 222941 Premier Pump, do not lift the
pump by the lift ring when the total weight exceeds
550 lb (250 kg).
Mount the pump (A) to suit the type of installation
planned. Fig. 3 on page 7 illustrates a ram-mounted
pump in a multi-gun header system. Pump dimensions
and the mounting hole layout are shown on pages 32
and 33.
If you are mounting the pump on a ram, refer to the
separate ram manual for installation and operation
instructions.
Air Line Accessories
Install the following accessories in the order shown in
Fig. 3, using adapters as necessary:
An air line lubricator (D) provides automatic air
motor lubrication.
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 3, using adapters as necessary:
Install a fluid shutoff valve (P) at each gun drop,
to isolate the gun and fluid accessories for servicing.
Install 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.
A fluid regulator (L) controls fluid pressure to the
gun/valve, and dampens pressure surges.
A gun or valve (S) dispenses the fluid. The gun
shown in Fig. 3 is a high pressure dispensing gun
for highly viscous fluids.
A gun swivel (R) allows freer gun movement.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
Fluid under high pressure can be injected through the skin and cause
serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
are instructed to relieve the pressure,
stop spraying/dispensing,
check or service any of the system equipment,
or install or clean the spray tip/nozzle.
1. Lock the gun/valve trigger safety.
2. Shut off the air supply to the pump.
3. In air-powered systems, close the bleed-type
master air valve (required in your system).
4. Unlock the gun/valve trigger safety.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Lock the gun/valve trigger safety.
7. Open the drain valve (required in your system)
and/or the pump bleeder valve, having a container
ready to catch the drainage.
8. Leave the drain valve open until you are ready to
spray/dispense again.
If you suspect that the spray tip/nozzle 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, nozzle, or hose end
coupling and relieve pressure gradually, then loosen
completely. Now clear the tip/nozzle or hose.
Packing Nut/Wet-Cup
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 before using the pump.
WARNING
For your safety, read the warning section FIRE
AND EXPLOSION HAZARD on page 5 before
flushing, and follow all the recommendations given
there.
Starting and Adjusting the Pump
Supply fluid to the pump, per the requirements of your
system.
Refer to Fig. 3 on page 7. Be sure the air regulator
(F) is closed. Then open the pump’s bleed-type master
air valve (E). Hold a metal part of the spray gun/dispensing valve (S) firmly to the side of a grounded
metal pail and hold the trigger open. Now slowly open
the air regulator until the pump starts.
Cycle the pump slowly until all the air is pushed out
and the pump and hoses are fully primed. Release the
spray gun/dispensing valve trigger and engage the
safety latch. The pump should stall against pressure
when the trigger is released.
If the pump fails to prime properly, open the bleeder
valve (35) slightly. Use the bleed hole on the underside
of the valve body (34) as a priming valve until the fluid
appears at the hole. See Fig. 4. Close the plug (35).
NOTE: When changing fluid containers with the hose
and gun already primed, open the bleeder valve plug
(35), to assist in priming the pump and venting air
before it enters the hose. Close the bleeder valve plug
when all air has been eliminated.
Fill the packing nut/wet-cup (2) 1/3 full with Graco
Throat Seal Liquid (TSL) or compatible solvent. See
Fig. 4. Using the supplied wrench (104), adjust the
packing nut weekly so it is just snug; do not overtighten. Follow the Pressure Relief Procedure above
before adjusting the packing nut.
WARNING
To reduce the risk of fluid injection, do not use your
hand or fingers to cover the bleed hole when
priming the pump.
308150 9
Operation
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the gun/valve is opened and closed. In a
circulating system, the pump will speed up or slow
down on demand, until the air supply is shut off.
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.
WARNING
To reduce the risk of overpressurizing your system,
which could result in component rupture and cause
serious injury, never exceed the specified maximum incoming air pressure to the pump (see the
Technical Data on pages 26–31).
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. A pump runaway
valve (C), which shuts off the air supply to the pump if
the pump accelerates beyond the pre-set speed, is
available. See Fig. 3 on page 7. If your pump accelerates quickly, or is running too fast, stop it immediately
and check the fluid supply. If the supply container is
empty and air has been pumped into the lines, refill the
container and prime the pump and the lines with fluid,
or flush and leave it filled with a compatible solvent. Be
sure to eliminate all air from the fluid system.

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 9.
For overnight shutdown, relieve the pressure. Stop
the pump at the bottom of the stroke to prevent fluid
from drying on the exposed displacement rod and
damaging the throat packings.
Always flush the pump before the fluid dries on the
displacement rod. Flush with water or a compatible
solvent. Relieve the pressure after flushing.
