meet your system’s requirements.  
Most models are supplied with a needle-type air con-  
trol valve (K) at the pump air inlet. Model 226951 is  
equipped with an air regulator kit (CC) instead (see  
Fig. 3). All models are supplied with an air line quick  
disconnect coupler (L) to connect the air line to the  
pump and accessories.  
CAUTION  
To prevent damaging the o-ring seals inside the suc-  
tion tube, do not use excessive force when extending  
the suction tube.  
All Other Models  
WARNING  
Refer to Fig. 2 and to the mounting accessories shown  
on page 35 for pump mounting methods.  
A bleed-type master air valve (D) and a fluid drain  
valve (G) are required in your system, to help re-  
duce the risk of serious injury, including splashing  
fluid in the eyes or on the skin, and injury from  
moving parts if you are adjusting or repairing the  
pump.  
Model  
226951  
Shown  
The bleed-type master air valve (D) relieves air  
trapped between this valve and the pump after the  
pump is shut off. Trapped air can cause the pump  
to cycle unexpectedly and result in serious injury,  
including amputation. Locate the valve close to the  
pump.  
CC  
J
L
The fluid drain valve (G) helps relieve pressure in  
the displacement pump, hose, and dispensing  
valve when shutting off the pump. Actuating the  
dispensing valve to relieve pressure may not be  
sufficient, especially if there is a clog in the hose or  
the dispensing valve.  
For automatic air motor lubrication, install an air line  
lubricator (C) downstream from the air regulator (if  
supplied) and all other accessories. Install a bleed-type  
master air valve (D) close to the pump. Next, install the  
air regulator (CC), if supplied. Install an air line filter (E)  
upstream from all other accessories, to remove harm-  
ful dirt and moisture from the compressed air supply.  
B
Using a suitable adapter, install the male disconnect  
pin fitting (J) in the air filter inlet. Install the air line  
quick disconnect coupler (L) on the air hose (F), but do  
not connect it to the pin fitting yet.

and disconnect the air hose. Push up on the ball of the  
intake valve (N) to drain the lower part of the pump.  
See Fig. 4. Turn the pump over to drain the upper part  
of the pump.  
WARNING  
PRESSURIZED EQUIPMENT HAZARD  
The system pressure must be manually relieved to  
prevent the system from starting or spraying acci-  
dentally. To reduce the risk of an injury from acci-  
dental spray from the gun, splashing fluid, or  
moving parts, follow the Pressure Relief Proce-  
dure whenever you:

Fig. 4  
Starting and Adjusting the Pump  
1. Shut off the air to the pump.  
With the air valve (K) or regulator (CC) closed, turn on  
the air supply and connect the air line coupler (L). See  
Figs. 3 or 5. Make sure all dispensing valves are open.  
2. Close the bleed-type master air valve (required in  
your system).  
3. Hold a metal part of the dispensing valve firmly to  
the side of a grounded metal pail, and trigger the  
valve to relieve pressure.  
Slowly open the air valve (K) or regulator (CC) until the  
pump cycles 5 to 20 cycles per minute. The pump it-  
self only takes a few strokes to prime. In a large sys-  
tem, however, the pump may have to be cycled for  
several minutes to fill all the lines. Once the entire sys-  
tem is primed, use the air valve or regulator to control  
pump speed and cycle rate; always use the lowest  
pressure necessary to get the desired results.  
4. Open the fluid drain valve (required in your sys-  
tem) to relieve all fluid pressure, having a contain-  
er ready to catch the drainage.  
5. Leave the drain valve open until you are ready to  
dispense again.  
When used for transfer and supply operations with no  
dispensing valve, the pump will run whenever air is  
supplied.  
If you suspect that the nozzle or hose is completely  
clogged, or that pressure has not been fully relieved  
after following the steps above, very slowly loosen the  
hose end coupling and relieve pressure gradually, then  
loosen completely. Now clear the nozzle or hose.  
Pump Shutdown  
Flush the Pump Before Using  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure at left.  
The pump was tested in lightweight oil, which was left  
in to protect pump parts. To prevent contamination of  
the fluid you are pumping, flush the pump with a com-  
patible solvent before using it.  
To flush the pump, connect a short hose to the pump  
outlet, insert the pump intake into a pail of compatible  
solvent, direct the hose into a pail, and start the pump  
as explained at right.  
1. Disconnect the air line coupler (L).  
2. Relieve the pressure.

Maintenance  
Fill the wet-cup (P) 1/2 full of Graco Throat Seal Liquid  
(TSL) or compatible solvent and keep it 1/2 full to keep  
fluid from drying on the displacement rod and damag-  
ing pump throat packings. See Fig. 5.  
WARNING  
Do not attempt to adjust the packing nut with the  
pump operating.  
Periodically, check the tightness of the packing nut (P).  
Relieve the pressure, then tighten enough to prevent  
leakage; no tighter. See Fig. 5. If the leakage can not  
be stopped, change the packings to prevent exposure  
to the fluid being pumped.  
Lubricate the throat packings frequently when you are  
pumping a non-lubricating fluid, or are shutting down  
for more than a few days. Some pumps have a grease  
fitting (DD) for this purpose. See Fig. 5.  
The accessory air line lubricator (C) provides automat-  
ic air motor lubrication. To manually lubricate the mo-  
tor, disconnect the air line at the air motor inlet, put  
about 15 drops of lightweight oil in the inlet, reconnect  
the air line and turn on the air to blow oil into the motor.  
L
J
Never allow the pump to run dry of 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, prime the  
pump and lines with fluid, or flush and leave filled with  
compatible solvent. Be sure to eliminate all air from the  
fluid system.

Displacement Pump Service  
3. Clean and inspect all piston parts. Replace parts  
CARBON STEEL DISPLACEMENT PUMPS,  
with leather, polyethylene, or  
PTFE packings  
as necessary. Reassemble the piston parts as  
shown, being sure that the lips of the u-cup pack-  
ing (21) are facing up. Screw the piston stud (22)  
into the valve housing (18) and torque to 31 NSm  
(23 ft–lb).  
This procedure covers the following displacement  
pumps. Refer to the parts drawings on the indicated  
pages for an illustration of your pump.  
4. When reassembling the piston to the connecting  
rod (17), screw the connecting rod all the way into  
the displacement rod (15). Tighten the upper nut  
(16) against the displacement rod and torque to 33  
NSm (24 ft–lb). Adjust the lower nut (16) to allow  
3.1 mm (0.125 in.) free travel for the disk (19).

D Model 237254, page 20.  
D Model 237449, page 21.  
D Model 237255, page 22.  
Throat Packings  
1. Remove the cylinder (13) and piston as explained  
previously. Remove the packing nut (1) and pull  
the displacement rod (15) out of the top of the out-  
let housing (6). Inspect the outer surface of the  
displacement rod for scoring or wear by running a  
finger over the surface or holding it up to the light  
at an angle.  
Before You Start  
1. Disconnect the displacement pump from the air  
motor as explained on page 11.  
2. Be sure you have all the necessary repair parts on  
hand to reduce downtime.  
2. Remove the throat packings from the outlet hous-  
ing (6).  
3. Repair Kits are available. For best results, use all  
the new parts in the kit even if the old parts look  
good. Refer to the parts drawing for your pump.  
3. Clean and inspect the parts for wear or damage.  
Lubricate the packings before reassembly. Install  
the parts one at a time, in the same position as  
before. The lips of the v-packings must face down  
against fluid pressure.  
Intake Valve  
1. Unscrew the intake valve housing (23) from the  
cylinder (13), using a strap wrench. Disassemble  
the valve and clean and inspect all parts.  
NOTE: On displacement pumps 215953, 215956, and  
237254, install the two leather v-packings (4) below the  
single PTFE v-packing (3).  
NOTE: On Models 237254 and 237255, inspect the  
ball (28) and seat in the housing (23) for wear or nicks.  
2. Replace parts as necessary. Reassemble as  
shown in the applicable parts drawing.  
4. Leave the packing nut (1) loose until the displace-  
ment rod (15) has been installed.  
Piston Valve  
CAUTION  
Insert the displacement rod from the top of the outlet  
housing to prevent shearing of the packings.  
1. Using a strap wrench, grip the cylinder (13) near  
the outlet housing (6) and unscrew it from the  
housing. Pull the cylinder down off the piston.  
Check the inner surface of the cylinder for scoring  
or wear by running a finger over the surface or  
holding the part up to the light at an angle.  
5. Tighten the packing nut just enough to prevent  
leaking. Overtightening can damage the packings.  
2. Loosen the lower nut (16) and unscrew the valve  
housing (18) from the connecting rod (17). Un-  
screw the piston stud (22).  
6. Reconnect the displacement pump to the air motor  
as explained on page 11.

3. Clean and inspect all piston parts. Replace parts  
CARBON STEEL DISPLACEMENT PUMPS,  
with rubber packings  
as necessary. Reassemble the piston parts as  
shown, being sure that the lips of the u-cup pack-  
ing (21) are facing up. Screw the piston stud (22)  
into the valve housing (18) and torque to 31 NSm  
(24 ft–lb).  
This procedure covers the following displacement  
pumps. Refer to the parts drawings on the indicated  
pages for an illustration of your pump.  
4. When reassembling the piston to the connecting  
rod (17), screw the connecting rod all the way into  
the displacement rod (15). Tighten the upper nut  
(16) against the displacement rod and torque to 33  
NSm (24 ft–lb). Adjust the lower nut (16) to allow  
3.1 mm (0.125 in.) free travel for the disk (19).

motor as explained on page 11.  
1. Remove the cylinder (13) and piston as explained  
previously. Remove the packing nut (1) and pull  
the displacement rod (15) out of the top of the out-  
let housing (6). Inspect the outer surface of the  
displacement rod for scoring or wear by running a  
finger over the surface or holding it up to the light  
at an angle.  
2. Be sure you have all the necessary repair parts on  
hand to reduce downtime.  
3. Repair Kit 218112 is available. For best results,  
use all the new parts in the kit even if the old parts  
look good.  
2. Remove the throat packings from the outlet hous-  
ing (6).  
Intake Valve  
3. Clean and inspect the parts for wear or damage.  
Lubricate the packings before reassembly. Install  
the parts one at a time, in the same position as  
before. The lips of the u-cup must face down  
against fluid pressure.  
1. Unscrew the intake valve housing (23) from the  
cylinder (13), using a strap wrench. Disassemble  
the valve and clean and inspect all parts.  
2. Replace parts as necessary. Reassemble as  
shown in the applicable parts drawing.  
4. Leave the packing nut (1) loose until the displace-  
ment rod (15) has been installed.  
Piston Valve  
1. Using a strap wrench, grip the cylinder (13) near  
the outlet housing (6) and unscrew it from the  
housing. Pull the cylinder down off the piston.  
Check the inner surface of the cylinder for scoring  
or wear by running a finger over the surface or  
holding the part up to the light at an angle.  
CAUTION  
Insert the displacement rod from the top of the outlet  
housing to prevent shearing of the packings.  
5. Tighten the packing nut just enough to prevent  
leaking. Overtightening can damage the packings.  
2. Loosen the lower nut (16) and unscrew the valve  
housing (18) from the connecting rod (17). Un-  
screw the piston stud (22).  
6. Reconnect the displacement pump to the air motor  
as explained on page 11.

3. Clean and inspect all piston parts. Be sure to in-  
STAINLESS STEEL DISPLACEMENT  
PUMPS, with polyethylene, leather,  
or PTFE packings  
spect the ball (25) and its seat on the piston stud  
(22) for wear or nicks. Replace parts as necessary.  
Reassemble the piston parts as shown, being sure  
that the lips of the u-cup packing (21) are facing  
up. Torque as specified on the applicable illustra-  
tion. Using a strap wrench, grip the cylinder (13)  
near the outlet housing (6) and screw it into the  
housing.  
This procedure covers the following displacement  
pumps. Refer to the parts drawings on the indicated  
pages for an illustration of your pump.  
D Model 215955, page 27.  
D Model 215958, page 28.  
D Model 237253, page 30.  
D Model 237256, page 31.  
NOTE: On Models 215955 and 237253, when reas-  
sembling the piston to the connecting rod (17), screw  
the connecting rod all the way into the displacement  
rod (15). Tighten the upper nut (16) against the dis-  
placement rod and torque to 33 NSm (24 ft–lb). Adjust  
the lower nut (16) to allow 3.1 mm (0.125 in.) free trav-  
el for the ball (25).  
Before You Start  
1. Disconnect the displacement pump from the air  
motor as explained on page 11.  
Also, when installing the cylinder (13), make sure that  
the knurled end is at the bottom.  
2. Be sure you have all the necessary repair parts on

Displacement Pump Service  
3. Clean and inspect all piston parts. Be sure to in-  
STAINLESS STEEL DISPLACEMENT  
PUMPS, with rubber packings  
spect the ball (25) and its seat on the piston stud  
(22) for wear or nicks. Replace parts as necessary.  
Reassemble the piston parts as shown, being sure  
that the lips of the u-cup packing (21) are facing  
up. Torque as specified on the applicable illustra-  
tion. Using a strap wrench, grip the cylinder (13)  
near the outlet housing (6) and screw it into the  
housing.  
This procedure covers the following displacement  
pumps. Refer to the parts drawings on the indicated  
pages for an illustration of your pump.  
D Model 220440, page 33.  
D Model 220439, page 34.  
NOTE: On Model 220440, when reassembling the pis-  
ton to the connecting rod (17), screw the connecting  
rod all the way into the displacement rod (15). Tighten  
the upper nut (16) against the displacement rod and  
torque to 33 NSm (24 ft–lb). Adjust the lower nut (16) to  
allow 3.1 mm (0.125 in.) free travel for the ball (25).  
Before You Start  
1. Disconnect the displacement pump from the air  
motor as explained on page 11.  
2. Be sure you have all the necessary repair parts on  
hand to reduce downtime.  
Also, when installing the cylinder (13), make sure that  
the knurled end is at the bottom.  
3. Repair Kit 218112 is available. For best results,  
use all the new parts in the kit even if the old parts  
look good.  
Throat Packings  
1. Remove the cylinder (13) and piston as explained  
previously. Remove the packing nut (1) and pull  
the displacement rod (15) out of the top of the out-  
let housing (6). Inspect the outer surface of the  
displacement rod for scoring or wear by running a  
finger over the surface or holding it up to the light  
at an angle.  
Intake Valve  
1. Unscrew the intake valve housing (23) from the  
cylinder (13), using a strap wrench. Disassemble  
the valve and clean and inspect all parts.  
2. Inspect the ball (28) and seat in the housing (23)  
for wear or nicks.  
2. Remove the throat packings from the outlet hous-  
ing (6).  
3. Replace parts as necessary. Reassemble as  
shown in the applicable parts drawing.  
3. Clean and inspect the parts for wear or damage.  
Lubricate the packings before reassembly. Install  
the parts one at a time, in the same position as  
before. The lips of the u-cup must face down  
against fluid pressure.  
Piston Valve  
1. Using a strap wrench, grip the cylinder (13) near  
the outlet housing (6) and unscrew it from the  
housing. Pull the cylinder down off the piston.  
Check the inner surface of the cylinder for scoring  
or wear by running a finger over the surface or  
holding the part up to the light at an angle.  
4. Leave the packing nut (1) loose until the displace-  
ment rod (15) has been installed.  
CAUTION  
Insert the displacement rod from the top of the outlet  
housing to prevent shearing of the packings.  
2. On Model 220440, loosen the lower nut (16) and  
unscrew the valve housing (18) from the connect-  
ing rod (17). Unscrew the piston stud (22).  
On Model 220439, remove the cotter pins (29)  
from the ball stop pin (30). Remove the ball stop  
pin and unscrew the piston stud (22) from the dis-  
placement rod (15). Be careful not to drop the ball  
(25).  
5. Tighten the packing nut just enough to prevent  
leaking. Overtightening can damage the packings.  
6. Reconnect the displacement pump to the air motor  
as explained on page 11.

The 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,
