FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
6. Fluid supply container: according to your local
code.
7. All solvent pails used when flushing, according to
your local code. Use only metal pails, which are
conductive, placed on a grounded surface. Do not
place the pail on a non-conductive surface, such
as paper or cardboard, which interrupts the
grounding continuity.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this dispensing equipment.
8. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun firmly to the side of a grounded metal
pail, then trigger the spray gun.

Parts Drawing.
Connect a electrically conductive fluid hose (L) to the
fluid filter (K), if used, or directly to the pump’s fluid
outlet.
NOTE: Contact you Graco distributor for available
Graco accessories. If you supply your own accesso-
ries, be sure they are adequately sized and pressure-
rated to meet the system’s requirements.
Use a electrically conductive 1/2 in. ID (minimum) air
hose (H) to supply air to the pump.
Air Line Accessories
The Typical Installation shown on page 6 is only a
guide for selecting and installing system components
and accessories. Contact your Graco distributor for
assistance in designing a system to suit your particular

System Accessories
D A bleed-type master air valve (D) 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 down-
stream from the air regulator.
Refer to the Typical Installation on page 6.
WARNING
A bleed-type master air valve (D) and a fluid drain
valve (J) are required in your system. These acces-
sories help reduce the risk of serious injury includ-
ing fluid injection, splashing in the eyes or on the
skin, and injury from moving parts if you are adjust-
ing or repairing the pump.
D A pump runaway valve (B) 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.
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.
D An air regulator (E) 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.
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.

Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 26.
Fluid Line Accessories
Install the following accessories in the positions shown
in the Typical Installation, using adapters as neces-
sary:
The pump is supplied with a bung adapter. To mount
the pump, loosen the bung adapter screw and slide the
adapter off the pump. Screw the bung adapter secure-
ly into the bung hole on the cover of the supply drum.
Carefully lower the pump through the bung adapter
and into the drum until it rests on the bottom, then pull
it back up 1/2 in. (13 mm). Tighten the bung adapter
screw to hold the pump in this position. Open the
drum’s vent plug to prevent a vacuum from forming in
the drum.
D A fluid drain valve (J) is required in your system
to relieve fluid pressure in the hose and gun (see
the WARNING at left). Install the drain valve point-
ing down, but so the handle points up when
opened.

Operation
Pressure Relief Procedure
WARNING
WARNING
Moving parts can pinch or amputate your fingers or
other body parts. When air is supplied to the motor,
the air motor piston (located behind the air motor
plates) moves. See Fig. 2. Therefore, never oper-
ate the pump with the air motor plates removed.
SKIN INJECTION HAZARD
Fluid under high pressure can be in-
jected 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:
Flush the Pump Before Using
The pump is tested with lightweight motor 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. If the
pump is being used to supply a circulating system,
allow the solvent to circulate until the pump is thor-
oughly flushed.
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 spray gun trigger safety.
2. Shut off the air to the pump.
WARNING
3. Close the bleed-type master air valve (required in
your system).
FIRE AND EXPLOSION HAZARD
For your safety, read the section FIRE
AND EXPLOSION HAZARD on page 4
before flushing and follow all the recom-
mendations given there.
4. Unlock the gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Lock the spray gun trigger safety.
7. Open the drain valve (required in your system),
having a container ready to catch the drainage.
8. 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. Now clear
the tip or hose.
308118

Operation
Starting and Adjusting the Pump
WARNING
To reduce the risk of overpressurizing your system,
which could result in component rupture and cause
serious injury, never exceed the Maximum Incom-
ing Air Pressure given on your pump or in the
Technical Data on pages 22 and 24.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
Keep the packing nut/wet-cup (14) filled with Graco
Throat Seal Liquid (TSL) or compatible solvent, to help
prolong the packing life. Adjust the packing nut weekly
so it is just tight enough to prevent leakage; do not
overtighten. See Fig. 2. Always relieve the pressure
before adjusting the packing nut.
See the Typical Installation on page 6. Be sure the
air regulator (E) and bleed-type master air valve (D)
are closed. Do not install the spray tip yet.
Mount the pump on the supply drum. On bung-style
drums, open the vent plug to prevent a vacuum from
forming in the drum. Hold a metal part of the spray gun
(M) firmly to the side of a grounded metal pail and hold
the trigger open. Then open the pump’s bleed-type
master air valve (D). Now slowly open the air regulator
until the pump starts, about 40 psi (280 kPa, 2.8 bar).
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 (B), which shuts off the air supply to the pump if
the pump accelerates beyond the pre-set speed, is
available. If your pump accelerates quickly, or is run-
ning 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.
Cycle the pump slowly until the air is pushed out and
the pump and hoses are fully primed. Release the
spray gun trigger and engage the safety latch. The
pump should stall against pressure when the trigger is
released.
Relieve the pressure, then install the spray tip in the
gun.
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.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun is opened and closed. In a
circulating system, the pump will run continuously and
will speed up or slow down as supply demands until
the air supply is shut off.
For overnight shutdown, relieve the pressure. Always
stop the pump at the bottom of the stroke to prevent
the fluid from drying on the exposed displacement rod
and damaging the throat packings.
Use an adequately sized air regulator (E) to control the
pump speed and the fluid pressure. Always use the
lowest air pressure necessary to get the desired
results. Higher pressures waste fluid and cause pre-
mature wear of the packings and spray tip.
Always flush the pump before the fluid dries on the
displacement rod. Relieve the pressure after flushing.

* To determine if the fluid hose or gun is obstructed, relieve the pressure. Disconnect the fluid hose and place a container at the
pump fluid outlet to catch any fluid. Turn on the air just enough to start the pump (about 20–40 psi [140–280 kPa, 1.4–2.8 bar]). If
the pump starts when the air is turned on, the obstruction is in the fluid hose or gun.

placement rod (1) and connecting rod (8) out the
bottom of the outlet housing (5).
Disassembly
When disassembling the pump, lay out all removed
parts in sequence to ease reassembly. See Fig. 4.
6. Secure the flats of the displacement rod (1) in a
vise. Unscrew the coupling nut (7) from the dis-
placement rod. Remove the connecting rod (8) and
attached parts.
NOTES
D Standard Repair Kit 224403 (UHMWPE/PTFE
packings) is available. For the best results, use all
the new parts in the kit. Parts included in the kit are
denoted with one asterisk, for example (2*).
7. Place the flats of the piston mounting stud (13) in a
vise. Loosen the jam nut (9) and unscrew the
adapter (10) from the piston mounting stud (13).
Set the connecting rod (8) aside. Remove one
cotter pin (12) and the ball stop pin (11), taking not
which set of holes it is in. Then remove the ball
(16).

D Clean all the parts thoroughly when disassembling.
Check them carefully for damage or wear, replacing
parts as needed.
8. Unscrew the piston stud (27) from the piston
mounting stud (13). Remove the piston packings
(29, 30), glands (28, 31) , shims (35), and washer
(26).
1. Remove the displacement pump from the air motor
as explained on page 14.
2. Unscrew the locking ring (20) from the cylinder
(15). See Fig. 4. Remove the intake valve housing
(21).
9. Remove the packing nut (14), throat packings (3,
25), and glands (2, 4) from the outlet housing (5).
3. Remove the o-ring (19), ball stop pin (17), and ball
(18) from the intake valve housing (21).
10. Inspect all parts for damage. Clean all parts and
threads with a compatible solvent before reassem-
bling. Inspect the polished outer surface of the
displacement rod (1) and inner surface of the
cylinder (15) for scratches, scoring, or other dam-
age, which can cause premature packing wear and
leaking. To check, run a finger over the surface or
hold the part up to the light at an angle. Be sure
the ball seats of the piston (27) and intake valve
housing (21) are not chipped or nicked. Replace
any worn or damaged parts.
4. Unscrew the cylinder (15) from the outlet housing
(5), note its orientation and carefully pull the cylin-
der off the pump. Remove the o-ring (6) from the
outlet housing.
NOTE: It is important to replace the cylinder in the
same orientation as both ends are NOT alike.
Failure to install correctly may result in failure of
pump or premature seal wear. For instructions on
how to verify correct orientation, see NOTE in step
7 on page 16.

5. Place the flats of the displacement rod (1) in a
Displacement Pump Service
vise. Apply thread lubricant to the bottom threads
of the rod. Couple the connecting rod (8) to the
displacement rod with the coupling nut (7). TIghten
the nut securely.
Reassembly
1. Lubricate the throat packings and install them in
the outlet housing (5) one at a time as follows, with
the lips of the v-packings facing down: the male
gland (4*), one UHMWPE v-packing (3*), two
PTFE v-packings (25*), one UHMWPE v-packing
(3*), and the female gland (2*). Apply thread
lubricant to the packing nut (14), and screw it
loosely into the outlet housing. See Fig. 4.
6. Place the o-ring (6) into the outlet housing (5).
Slide the displacement rod and connecting rod
assembly up into the outlet housing (5) until the
displacement rod protrudes from the packing nut
(14).
2. Lubricate the piston packings and install them on
the piston stud (27) one at a time in the following
order, with the lips of the v-packing facing up: the
shims (35; use 0–3 as required), the female gland
(31*), one UHMWPE v-packing (30*), two PTFE
v-packings (29*), one UHMWPE v-packing (30*),
the male gland (28*), and the washer (26*). See
Fig. 4.
NOTE: Before replacing the pump cylinder, note its
orientation. Failure to install correctly may result in
failure of pump or premature seal wear. Inspect the
inner diameter of both ends of the cylinder for
smoothness and size. The rougher and larger end
should mate with the outlet housing (5) upon
reassembly.
3. Apply thread sealant and screw the piston stud
(27) onto the piston mounting stud (13). Torque to
50–70 ft-lb (68–95 NSm). Install the piston ball
(16*) on the piston seat. Slide the ball stop pin
(11*) into the desired set of holes, and secure with
the cotter pin (12*).
7. Apply thread lubricant to the top threads of the
cylinder (15). Slide the cylinder straight up over the
connecting rod (8) and displacement rod (1), being
careful not to scratch the cylinder by tilting it.
Screw the cylinder into the outlet housing (5).
4. Check that the coupling nut (7), jam nut (9) and
adapter (10) are in place on the connecting rod (8).
The bottom of the adapter (10) should be flush
with the end of the rod (8); tighten the jam nut (9)
down securely to lock these parts. Apply thread
sealant to the male threads of the adapter (10).
Screw the piston mounting stud (13) onto the
connecting rod adapter (10), and torque to 50–70
ft-lb (68–95 NSm).
8. Install the ball (18*), o-ring (19) and ball stop pin
(17*) in the intake valve housing (21). Apply thread
lubricant to the bottom threads of the cylinder (15).
Place the intake valve assembly in the locking ring
(20), and screw the ring onto the cylinder (15).
9. Reconnect the displacement pump to the motor as
explained on page 14.

Graco Standard Warranty
Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the
date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco,
Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub-
stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection
with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured
by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide
purchaser with reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
