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.

Installation  
Refer to the Typical Installation drawing (Fig. 2).  
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.

Packing Nut  
D check or service any of the system equipment,  
D or install or clean the spray tip.  
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.

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.
