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 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 freer gun/valve
movement.

Air Line Accessories

Install the following accessories in the order shown in
Fig. 3, using adapters as necessary:

D An air line lubricator (D) provides automatic air

motor lubrication.

D 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.

D An air regulator (F) controls pump speed and out-

let 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.

D 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.

D An air manifold (G) has a swivel air inlet. It

mounts to a wall bracket, and provides ports for
connecting lines to air-powered accessories.

D An air line filter (J) removes harmful dirt and

moisture from the compressed air supply.

D 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 222939 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 illustrates a wall-mounted system.
Pump dimensions and the mounting hole layout are
shown on pages 36 and 37.

If you are using an elevator or a cart, refer to the
separate manuals supplied with those components for
installation and operation instructions.

Fluid Line Accessories

Install the following accessories in the positions shown
in Fig. 3, 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. 3 is an airless spray gun for light to
medium viscosity fluids.

D A gun swivel (R) allows freer gun movement.

D A suction kit (T) allows the pump to draw fluid

from a 200 liter (55 gallon) drum.

(ALL PUMPS)

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually
relieved to prevent the system from

starting or spraying accidentally. 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:

D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tips.

1. Lock the gun/valve trigger safety.

2. Shut off the air or hydraulic supply to the pump.

3. In air-powered systems, close the bleed-type
master air valve (required in your system).

Packing Nut/Wet-Cup

Fill the packing nut/wet-cup (3) 1/3 full with Graco
Throat Seal Liquid (TSL) or compatible solvent. See
Fig. 5. Using the supplied wrench (104), adjust the
packing nut weekly so it is just snug; do not overtigh­ten. Follow the Pressure Relief Procedure at left.

Flushing the Pump

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 or
Explosion Hazard on page 5 before flushing, and

follow all recommendations given there.

Model 222837
Shown

In hydraulic-powered systems, close the hydraulic
supply line valve first, then the return line valve.

4. Unlock the gun/valve safety latch.

5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun/valve to
relieve pressure.

6. Lock the gun 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 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. Now clear
the tip or hose.

Operation/Maintenance

(AIR-POWERED PUMPS)

Starting and Adjusting the Pump

1. Refer to Fig. 3 on page 8. Connect the suction kit
(T) to the pump’s fluid inlet, and place the tube into
the fluid supply.

2. 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.

3. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed. Release
the gun/valve trigger and lock the trigger safety
latch. The pump should stall against pressure
when the trigger is released.

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 (34) when
priming the pump. Use a crescent wrench to open
and close the bleeder plug (35). Keep your hands
away from the bleed hole.

6. Use the air regulator 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

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing
your system, which could cause compo­nent rupture and serious injury, never

exceed the specified Maximum Incoming Air Pres­sure to the pump (see the Technical Data on

pages 32–35).

7. 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 8.
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.

4. 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. 5.
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
when all air has been eliminated.

5. 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.

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 12.

For overnight shutdown, relieve the pressure. Stop
the pump at the bottom of its 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. Never leave water or water-based
fluid in the pump overnight. First, flush with water or a
compatible solvent, then with mineral spirits. Relieve
the pressure, but leave the mineral spirits in the pump
to protect the parts from corrosion.

Starting and Adjusting the Pump

1. Refer to Fig. 4 on page 10. Connect the suction kit
(T) 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. Make certain that the supply line shutoff valve (U)
and the return line shutoff valve (V) are closed.

4. Start the hydraulic power supply.

5. Hold a metal part of the gun/valve (S) firmly to the
side of a grounded metal pail and hold the trigger
open.

9. With the pump and lines primed, and with ade­quate hydraulic 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
hydraulic power supply is shut off.

10. Use the fluid pressure gauge (F) and flow control
valve (G) to control the pump speed and the fluid
outlet pressure. Always use the lowest hydraulic
flow and pressure necessary to get the desired
results. Higher pressures cause premature tip/noz­zle and pump wear.

WARNING

6. Open the return line shutoff valve (V) first, then
slowly open the supply line shutoff valve (U).

7. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed. Release
the gun/valve trigger and engage the safety latch.
The pump should stall against pressure when the
trigger is released.

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 (34) when
priming the pump. Use a crescent wrench to open
and close the bleeder plug (35). Keep your hands
away from the bleed hole.

8. If the pump fails to prime properly, open the

To reduce the risk of overpressurizing
your system, which could cause compo­nent rupture and serious injury, never

exceed 10 MPa, 103 bar (1500 psi) Maximum Hy­draulic Input Pressure to the pump, or 140 bar
(2000 psi) Maximum Fluid Working Pressure (see

the Technical Data on page 35).

To prevent overpressurizing the hydraulic motor or
its seals, always shut off the supply line valve (U)
first, then shut off the return line valve (V).

CAUTION

Do not allow the hydraulic oil temperature to exceed
54_C (130_F). The pump seals will wear faster and
leakage may occur if the pump is operated at higher
oil temperatures.

11. 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. 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.

(HYDRAULIC-POWERED PUMPS)

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 12.

For overnight shutdown, relieve the pressure on page

12. 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. Never leave water or water-based
fluid in the pump overnight. First, flush with water or a
compatible solvent, then with mineral spirits. Relieve
the pressure, but leave the mineral spirits in the pump
to protect the parts from corrosion.

Disconnecting the Displacement Pump

WARNING

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 12.

1. Flush the pump, if possible. Stop the pump at the

bottom of its stroke. Relieve the pressure.

2. Disconnect the air or hydraulic hose. Plug all
hydraulic hoses immediately, to prevent contami­nation of the hydraulic system. Hold the fluid outlet
fitting (4) with a wrench to keep it from being
loosened while you disconnect the fluid hose.

CAUTION

Be sure to use at least two people when lifting,
moving, or disconnecting the pump. This pump is too
heavy for one person. If you are disconnecting the
displacement pump from a motor which is still
mounted (for example, on a wall bracket), be sure to
support the displacement pump while it is being
disconnected, to prevent it from falling and causing
injury or property damage. Do this by securely brac­ing the pump, or by having at least two people hold it
while another disconnects it.

4. Using adjustable wrenches, unscrew the coupling
nut (103) from the connecting rod adapter (102).
Remove the coupling collars (108). Take care not
to lose or drop them. See Fig. 6.

5. Hold the tie rod flats with a wrench to keep the
rods from turning. Unscrew the nuts (106) from the
tie rods (107). Carefully remove the displacement
pump (105) from the motor (101).

6. Refer to page 20 for displacement pump service.
To service the air or hydraulic motor, refer to the
separate motor manual, supplied.

Reconnecting the Displacement Pump

WARNING

To reduce the risk of pinching or injuring hands or
fingers caught between the hydraulic motor drip
pan and the coupling nut, always use connecting
rod adapter 184595 and tie rods 184596 on
Model 222892 Viscount Pump. Never use con-
necting rod adapter 184451 and tie rods 184452
on Model 222892; those parts do not allow
sufficient clearance between the drip pan and
coupling nut.

NOTE: On Premier models, ensure that the rod adapt­er (102) has not loosened during maintenance. Proper
torque is necessary to prevent the rod adapter from
loosening during the pump operation.

If the rod adapter (102) has loosened during mainte­nance, remove the adapter and apply LoctiteR 2760t
(or equivalent) to the rod adapter and air motor piston
threads, and then torque as specified in Fig. 6.

1. Screw the connecting rod adapter (102) to the air
motor shaft. Torque as specified in Fig. 6.

2. Screw the tie rods (107) into the air motor (101).
Using a wrench on the tie rod flats, torque as
specified.

3. Make sure the coupling nut (103) and the coupling
collars (108) are in place on the displacement rod
(1).

4. Use at least two people to hold the displacement
pump while another reconnects it to the motor (see
the CAUTION at left). Orient the pump’s fluid
outlet to the air or hydraulic inlet as was noted in
step 3 under Disconnecting the Displacement
Pump. Position the displacement pump (105) on
the tie rods (107).

5. Screw the nuts (106) onto the tie rods (107) and
torque as noted in Fig. 6.

6. Screw the coupling nut (103) onto the connecting
rod adapter (102) loosely. Hold the connecting rod
adapter flats with a wrench to keep it from turning.
Use an adjustable wrench to tighten the coupling
nut. Torque as noted in Fig. 6.

7. Torque the packing nut (3) to 135–169 NSm
(100–125 ft-lb).

8. Reconnect all hoses. Reconnect the ground wire if
it was disconnected. Fill the wet-cup (3) 1/3 full of
Graco Throat Seal Liquid or compatible solvent.

9. Turn on the air or hydraulic power supply. On
hydraulic pumps, open the hydraulic return line
valve first, then the supply line valve. Run the
pump slowly to ensure that it operates properly.

7. Stand the cylinder (7) upright on a wooden block.
Using a rubber mallet or an arbor press, drive the
displacement rod (1) and piston assembly down
into the cylinder as far as possible, then place the
cylinder on its side and continue to drive the rod
out the bottom until the piston comes free. Pull the
rod and piston from the cylinder, being careful not
to scratch the rod or cylinder.

CAUTION

To reduce the possibility of costly damage to the rod
(1) and cylinder (7), always use a rubber mallet or an
arbor press to drive the rod out of the cylinder. Be
sure to place the cylinder on a soft block of wood.
Never use a hammer to drive the rod.

NOTE: Service Tool 109507 is available as an acces­sory. The tool fits over the top of the displacement rod
(1), making it easier to apply a 24 inch adjustable
wrench or 3/4 in. drive socket when disconnecting the
rod from the piston assembly.

8. Put the flats of the piston seat housing (12) in a
vise. Unscrew the rod (1) from the housing (12),
leaving the ball guide (9) assembled to the rod. Be
careful to catch the piston ball (10) as you sepa­rate the housing (12) and ball guide (9), so that it
doesn’t fall and suffer damage.

9. Remove the glands and v-packings (P) from the
piston seat housing (12). Inspect the ball (10) and
ball seat (B) on the housing (12) for wear or dam­age.

5. Remove the seal (6) from the bottom of the outlet
housing (19). Unscrew the packing nut (3). Re­move the glands and v-packings (T) from the
housing. Do not remove the outlet fitting (4) and
o-ring (5) unless they need replacement.

6. Unscrew the handle of the bleeder valve plug (35)
completely from the valve body (34). Clean the
valve threads and the bleed hole. It is not neces­sary to remove the valve housing from the pump
outlet housing (19).

(1), making it easier to apply a 24 inch adjustable
wrench or 3/4 in. drive socket when connecting the rod
to the piston assembly.

3. Apply anti-seize lubricant 222955 to the threads
and mating faces of the ball guide (9) and piston
seat housing (12). Place the flats of the piston seat
housing in a vise. Place the ball (10) on the piston
seat. Screw the assembled rod (1) and ball guide
(9) onto the piston assembly hand tight, then
torque to 459–481 NSm (338–354 ft-lb).

4. Use an arbor press to reinstall the rod (1) into the
cylinder (7), as follows. (The cylinder is symmetri­cal, so either end may face up.) Lubricate the
piston packings (P). With the piston end facing
down, lower the rod into the cylinder. Start the
piston into the cylinder as much as possible, then
drive the rod and piston the rest of the way into the
cylinder with the arbor press.

5. Lubricate the o-ring (27*) and seal (6*). Install the
o-ring on the intake seat housing (15). Install the
intake seat housing (15), intake ball (16), ball guide
