WARNING
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.
7. Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
1. Pump: use a 12 gauge (1.5 mm@) minimum ground
wire and clamp. See Fig. 1. Loosen the grounding
lug locknut (W) and washer (X). Insert one end of
the ground wire (Y) into the slot in lug (Z) and
tighten the locknut securely. Connect the other end
of the wire to a true earth ground. Order Part No.

Air Line Accessories
Install the following accessories in the order shown in
Fig. 2, using adapters as necessary:
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 skin 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.

motor lubrication.
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.
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.
Order Part No. 113333.
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 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. 238635.
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.
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 23.

Air and Fluid Hoses
D A second bleed-type air valve (G) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Ensure that you have an adequate compressed air
supply. Refer to the performance chart on page 20 to
find the air consumption of your pump.
Fluid Line Accessories
Be sure all air and fluid hoses are properly sized and
pressure-rated for your system. Use only electrically
conductive air and fluid hoses. Fluid hoses must have
spring guards on both ends.
Install the following accessories in the positions shown
in Fig. 2, using adapters as necessary:
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 the
valve is opened.
Connect an electrically conductive fluid hose (L) to the
pump’s 3/8 npt(f) fluid outlet. Use of a short whip hose
between the main fluid hose (L) and the gun (M) allows
freer gun movement.

Keep the packing nut/wet-cup (36) filled with Graco
Throat Seal Liquid (TSL) or compatible solvent, to help
prolong the packing life. See Fig. 3.
1. Lock the gun trigger safety.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
2. Close the bleed-type master air valve (D, required
in your system). See Fig. 2.
3. Unlock the gun trigger safety.
The packing nut is torqued at the factory and is ready
for operation. If it becomes loose and there is leaking
from the throat packings, relieve pressure, then torque
the nut to 18–20 ft–lb (24–27 N.m). Do this whenever
necessary. Do not overtighten the packing nut.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
5. Lock the gun trigger safety.
Flush the Pump Before First Use
6. Open the drain valve (J, required in your system),
having a container ready to catch the drainage.
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 11.
7. Leave the drain valve open until you are ready to
spray again.

Operation
Use an adequately sized air regulator (E) to control the
Starting and Adjusting the Pump
pump speed and the fluid pressure. Always use the
lowest air pressure necessary to get the desired re-
sults. Higher pressures waste fluid and cause prema-
ture wear of the pump packings and spray tip.
See Fig. 2 on page 7. Be sure the air regulator (E)
and bleed-type master air valve (D) are closed. Do not
install the spray tip yet!
Connect a suction hose (N) to the pump’s fluid inlet.
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 (0.3 MPa, 3 bar).
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause compo-
nent rupture and serious injury, never
exceed the Maximum Air Input Pressure marked
on the pump. Refer to the Technical Data on page
20.
Cycle the pump slowly until all the air is pushed out
and the pump and hoses are fully primed. Release the
spray gun trigger and lock the trigger safety. The pump
should stall against pressure when the trigger is re-
leased.
CAUTION
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
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.
Relieve the pressure. Install the spray tip as explained
in your separate gun manual.
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 circu-
lating system, the pump will run continuously and will
speed up or slow down as supply demands until the air
supply is shut off.
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. See Fig. 2 on page
7. Contact your Graco distributor for further infor-
mation.

Operation
Shutdown and Care of the Pump
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 9.
Model 223586 Shown
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.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing below.

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 [0.14–0.28 MPa, 1.4–2.8 bar]). If the pump starts when the air is turned on, the obstruction is in the fluid
hose or gun.

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
1. Flush the pump if possible. Stop the pump at the
bottom of its stroke. Relieve the pressure.
2. Disconnect the air and fluid hoses. Remove the
pump from its mounting. Note the relative position
of the pump’s fluid outlet to the air motor’s air inlet.

Disassembly
When disassembling the pump, lay out all removed
parts in sequence, to ease reassembly. Refer to Fig. 5.
Reassembly
1. Lubricate the throat packings and install them in
the outlet housing (35) one at a time as follows,
with the lips of the v-packings facing down: the
male gland (24*), one leather v-packing (18*), one
PTFE (23*), one leather (18*), one PTFE (23*),
one leather (18*), one PTFE (23*), and the female
gland (25*). Install the packing nut (36) loosely.
See the Throat Packing Detail in Fig. 5.
NOTE: Repair Kit 235635 is available. For the best
results, use all the new parts in the kit. Parts included
in the kit are denoted with an asterisk, for example
(17*).
Clean all the parts thoroughly when disassembling.
Check them carefully for damage or wear, replacing
parts as needed.
2. If you removed the sleeve (20), reinstall it in the
outlet housing (35), making sure to replace the
gasket (19*). Be sure the tapered end of the
sleeve faces down, toward the pump intake.
1. Remove the displacement pump from the air motor
as explained on page 13.
2. Unscrew the intake valve housing (33) from the
outlet housing (35). If it is difficult to remove,
squirt penetrating oil around the threads and gently
tap around the valve housing with a plastic ham-
mer to loosen it. See Fig. 5.
3. Lubricate the piston packings and install them onto
the piston stud (34) one at a time in the following
order, with the lips of the v-packings facing up: the
female gland (25*), one PTFE v-packing (23*), one
leather v-packing (18*), one PTFE (23*), one leath-
er (18*), one PTFE (23*), one leather (18*), the
male gland (24*), and the packing retainer (22).
See the Piston Packing Detail in Fig. 5.
3. Remove the ball stop pin (29), o-ring retainer (31),
o-ring (30), guide (32) and ball (28) from the intake
valve housing (33).
4. Loosen the packing nut (36). Push the displace-
ment rod (26) down as far as possible, then pull it
out the bottom of the outlet housing (35).
4. Use thread sealant on the piston stud (34). Install
the piston ball (17*) on the piston and screw the
piston valve assembly into the displacement rod
(26). Torque to 55–65 ft–lb (74–88 N.m).
5. Secure the flats of the displacement rod (26) in a
vise. Screw the piston stud (34) out of the rod. Re-
move the ball (17), retainer (22), packings (18, 23)
and glands (24, 25).
6. Remove the packing nut (36), throat packings (18,
23) and glands (24, 25) from the outlet housing
(35).
5. Insert the displacement rod (26) into the bottom of
the outlet housing (35), being careful not to scratch
the sleeve (20). Push the rod straight up until it
protrudes from the packing nut (36).
7. Inspect all parts for damage. Clean all parts and
threads with a compatible solvent before reassem-
bling. Inspect the polished surfaces of the dis-
placement rod (26) and sleeve (20) for scratches,
scoring or other damage, which can cause prema-
ture 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 pis-
ton (R) and intake valve housing (S) are not
chipped or nicked. Replace any worn or damaged
parts.
6. Install the ball (28*), guide (32), o-ring (30*), retain-
er (31), and ball stop pin (29) in the intake valve
housing (33). Apply thread lubricant and screw the
intake housing into the outlet housing (35). Torque
to 55–65 ft–lb (74–88 N.m).
NOTE: If the sleeve (20) needs replacement and is
hard to remove, contact your Graco distributor.
7. Reconnect the displacement pump to the air motor
as explained on page 13.

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.
