close to the pump and use it to relieve trapped  
air. See the WARNING at left. Locate the other  
master air valve (E) upstream from all air line  
accessories and use it to isolate them during  
cleaning and repair.  
WARNING  
A bleed-type master air valve (B) is required in  
your system to relieve air trapped between this  
valve and the pump. Trapped air can cause the  
pump to cycle unexpectedly, which could result in  
serious injury, including splashing in the eyes or on  
the skin, injury from moving parts, or contamination  
from hazardous fluids. See Fig. 2.  
c. The air line filter (F) removes harmful dirt and  
moisture from the compressed air supply.  
2. Install an electrically conductive, flexible air hose  
(A) between the accessories and the 1/2 npt(f)  
pump air inlet (N). See Fig. 2. Use a minimum 1/2”  
(13 mm) ID air hose.  
1. Install the air line accessories as shown in Fig. 2.  
Mount these accessories on the wall or on a  
bracket. Be sure the air line supplying the acces-  
sories is electrically conductive.  
3. Screw an air line quick disconnect coupler (D) onto  
the end of the air hose (A); be sure the coupler  
porting is large enough to not restrict the air flow,  
which will affect pump performance. Screw the  
mating fitting into the pump air inlet snugly. Do not  
connect the coupler (D) to the fitting until you are  
ready to operate the pump.  
a. Install an air regulator (C) and gauge to control

1. Refer to Parts Drawings. Connect air line to pump  
as in preceding steps.  
1. The pump fluid inlet (R) is a 2” raised face flange.  
Refer to Flange Connections on page 9.  
2. Connect 1/4 in. O.D. tubing to push type connec-  
tors (14) on air motor of pump.  
2. If the fluid inlet pressure to the pump is more than  
25% of the outlet working pressure, the ball check  
valves will not close fast enough, resulting in  
inefficient pump operation.  
NOTE: by replacing the push type connectors, other  
sizes or types of fittings may be used. The new fittings  
will require 1/8 in. npt threads.  
3. At inlet fluid pressures greater than 15 psi  
(0.1 MPa, 1 bar), diaphragm life will be shortened.  
3. Connect remaining ends of tubes to external air  
signal, such as Graco’s Cycleflo (P/N 195264) or  
Cycleflo II (P/N195265) controllers.

Installation  
Changing the Orientation of the Fluid Inlet  
Fluid Pressure Relief Valve  
and Outlet Ports  
The pump is shipped with the fluid inlet (R) and outlet  
(S) ports facing the same direction. See Fig. 4. To  
change the orientation of the inlet and/or outlet port:  
CAUTION  
Some systems may require installation of a pres-  
sure relief valve at the pump outlet to prevent  
overpressurization and rupture of the pump or  
hose. See Fig. 5.  
1. Remove the screws and washers (106, 112, 113  
and 114) holding the inlet (102) and/or outlet (103)  
manifold to the covers (101).  
Thermal expansion of fluid in the outlet line can  
cause overpressurization. This can occur when  
using long fluid lines exposed to sunlight or ambi-  
ent heat, or when pumping from a cool to a warm  
area (for example, from an underground tank).  
2. Reverse the manifold and reattach. Install the  
screws and washers and torque to 150–160 in–lb  
(17–18 NSm). See Torque Sequence, page 32.

erratic pump operation.  
WARNING  
If the muffler (P) is installed directly to the air exhaust  
port, apply PTFE thread tape or anti–seize thread  
lubricant to the muffler threads before assembly.  
FIRE AND EXPLOSION HAZARD  
Be sure to read and follow the warnings  
and precautions regarding TOXIC  
FLUID HAZARD, and FIRE OR EXPLO-  
SION HAZARD on page 4, before op-  
erating this pump.  
To provide a remote exhaust:  
1. Remove the muffler (P) from the pump air exhaust  
port.  
Be sure the system is properly ventilated for your  
type of installation. You must vent the exhaust to a  
safe place, away from people, animals, food handl-  
ing areas, and all sources of ignition when pumping  
flammable or hazardous fluids.  
2. Install an electrically conductive air exhaust hose  
(T) and connect the muffler (P) to the other end of  
the hose. The minimum size for the air exhaust  
hose is 3/4 in. (19 mm) ID. If a hose longer than 15  
ft (4.57 m) is required, use a larger diameter hose.  
Avoid sharp bends or kinks in the hose. See Fig. 6.  
Diaphragm failure will cause the fluid being  
pumped to exhaust with the air. Place an appropri-  
ate container at the end of the air exhaust line to  
catch the fluid. See Fig. 6.  
3. Place a container (U) at the end of the air exhaust  
line to catch fluid in case a diaphragm ruptures.

Operation  
1. Be sure the pump is properly grounded. Refer to  
Pressure Relief Procedure  
Grounding on page 6.  
WARNING  
2. Check all fittings to be sure they are tight. Be sure  
to use a compatible liquid thread sealant on all  
male threads. Tighten the fluid inlet and outlet  
fittings securely.  
PRESSURIZED EQUIPMENT HAZARD  
The equipment stays pressurized until pressure is  
manually relieved. To reduce the risk of serious  
injury from pressurized fluid, accidental spray from  
the gun or splashing fluid, follow this procedure  
whenever you:  
3. Place the suction tube (if used) in the fluid to be  
pumped.  
D Are instructed to relieve pressure,  
D Stop pumping,  
D Check, clean or service any system equipment,  
D Install or clean fluid nozzles.  
NOTE: If the fluid inlet pressure to the pump is more  
than 25% of the outlet working pressure, the ball check  
valves will not close fast enough, resulting in inefficient  
pump operation.  
1. Shut off the air to the pump.  
2. Open the dispensing valve, if used.  
4. Place the end of the fluid hose (L) into an appropri-  
ate container.  
3. Open the fluid drain valve to relieve all fluid pres-  
sure, having a container ready to catch the drain-  
age.  
5. Close the fluid drain valve (J). See Fig. 2.  
Flush the Pump Before First Use  
The pump was tested with lightweight oil, which is left  
in the fluid passages to protect parts. To avoid contam-  
inating your fluid with oil, flush the pump with a com-  
patible solvent before using the equipment. Follow the  
steps under Starting and Adjusting the Pump.  
6. With the pump air regulator (C) closed, open all  
bleed-type master air valves (B, E).  
7. If the fluid hose has a dispensing device, hold it  
open while continuing with the following step.  
Starting and Adjusting the Pump  
WARNING  
8. Slowly open the air regulator (C) until the pump  
starts to cycle. Allow the pump to cycle slowly until  
all air is pushed out of the lines and the pump is  
primed.  
TOXIC FLUID HAZARD  
Hazardous fluid or toxic fumes can  
cause serious injury or death if splashed  
in the eyes or on the skin, inhaled, or  
swallowed. Do not lift a pump under pressure. If  
dropped, the fluid section may rupture. Always fol-  
low the Pressure Relief Procedure above before  
lifting the pump.  
If you are flushing, run the pump long enough to  
thoroughly clean the pump and hoses. Close the  
air regulator. Remove the suction tube from the  
solvent and place it in the fluid to be pumped.

Operation  
NOTE: Leaving air pressure applied to the air motor for  
Operation of Remote Piloted Pumps  
extended periods when the pump is not running may  
shorten the diaphragm life. Using a 3–way solenoid  
valve to automatically relieve the pressure on the air  
motor when the metering cycle is complete prevents  
this from occurring.  
1. Fig. 2 and Parts Drawings. Follow preceding steps  
1 through 7 of Starting and Adjusting Pump.  
2. Open air regulator (C).  
Pump Shutdown  
WARNING  
The pump may cycle once before the external sig-  
nal is applied. Injury is possible. If pump cycles,  
wait until end before proceeding.  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure at left.  
3. Pump will operate when air pressure is alternately  
applied and relieved to push type connectors (14).  
At the end of the work shift, relieve the pressure.  
Maintenance  
Flush the pump often enough to prevent the fluid you  
are pumping from drying or freezing in the pump and  
damaging it. Flush with a fluid that is compatible with  
the fluid you are pumping and with the wetted parts in  
your system. Check with your fluid manufacturer or  
supplier for recommended flushing fluids and flushing  
frequency.  
Lubrication  
The air valve is designed to operate unlubricated.  
However, if lubrication is desired, every 500 hours of  
operation (or monthly) remove the hose from the pump  
air inlet and add two drops of machine oil to the air  
inlet.  
Always flush the pump and relieve the pressure before  
storing it for any length of time.  
CAUTION  
Tightening Threaded Connections  
Do not over-lubricate the pump. Oil is exhausted  
through the muffler, which could contaminate your  
fluid supply or other equipment. Excessive lubrica-  
tion can also cause the pump to malfunction.  
Before each use, check all hoses for wear or damage,  
and replace as necessary. Check to be sure all  
threaded connections are tight and leak free. Check  
fasteners. Tighten or retorque as necessary. Although  
pump use varies, a general guideline is to retorque  
fasteners every two months. See Torque Sequence,  
page 32.  
Flushing and Storage  
WARNING  
Preventive Maintenance Schedule  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 12.  
Establish a preventive maintenance schedule, based  
on the pump’s service history. This is especially impor-  
tant for prevention of spills or leakage due to dia-  
phragm failure.

Fig. 13.  
shaft (24). Remove one diaphragm (401), and the  
inner plate (104). See Fig. 13.  
For overmolded diaphragms: Grip both dia-  
phragms securely around the outer edge and  
rotate counterclockwise. One diaphragm assembly  
will come free and the other will remain attached to  
the shaft. Remove the freed diaphragm and air  
side plate.  
2. Grease the length and ends of the diaphragm shaft  
(24) and slide it through the housing (1).  
3. Assemble the inner diaphragm plates (104), dia-  
phragms (401*), PTFE diaphragms (403*, if pres-  
ent), and outer diaphragm plates (105) exactly as  
shown in Fig. 13. These parts must be assembled  
correctly.  
NOTE: PTFE models include a PTFE diaphragm (403)  
in addition to the backup diaphragm (401).  
5. Pull the other diaphragm assembly and the dia-  
phragm shaft (24) out of the center housing (1).  
Hold the shaft flats with a 19 mm open–end  
wrench, and remove the outer plate (105) from the  
shaft. Disassemble the remaining diaphragm  
assembly.  
4. Apply medium-strength (blue) LoctiteR or equiva-  
lent to the threads of the fluid-side plates (105).  
Hold one of the outer plates (105) with a wrench,  
and torque the other outer plate to 20 to 25 ft-lb  
(27 to 34 NSm) at 100 rpm maximum. Do not  
over-torque.  
For overmolded diaphragms: Pull the other dia-  
phragm assembly and the diaphragm shaft (24)  
out of the center housing (1). Hold the shaft flats  
with a 19 mm open–end wrench and remove the  
diaphragm and air side plate from the shaft.  
5. Align the fluid covers (101) and the center housing  
(1) so the arrows (A) on the covers face the same  
direction as the air valve (B). Secure the covers  
with the screws (107 and 108), handtight. Install  
the longer screws (108) in the top and bottom  
holes of the covers. See Fig. 12.  
6. Inspect the diaphragm shaft (24) for wear or  
scratches. If it is damaged, inspect the bearings  
(19) in place. If the bearings are damaged, refer to  
page 23.  
6. First, torque the longer screws (108) oppositely  
and evenly to 190–220 in-lb (21–25 NSm), using a  
13 mm socket wrench. Then torque the shorter  
screws (107). See Torque Sequence, page 32.  
7. Reach into the center housing (1) with an o-ring  
pick and hook the u-cup packings (402), then pull  
them out of the housing. This can be done with the  
bearings (19) in place.  
8. Clean all parts and inspect for wear or damage.  
Replace parts as needed.  
7. Reassemble the ball check valves and manifolds  
as explained on page 18.

Reassembly – Overmolded Diaphragms  
5. Assemble the other diaphragm assembly to the  
shaft as explained in step 2. This diaphragm will  
be lifted off the air cover at this point.  
WARNING  
To reduce the risk of serious injury, including  
amputation, do not put your fingers or hand be-  
tween the air cover and the diaphragm.  
6. Supply the pump with low pressure air (less than 7  
psi [0.05 MPa, 0.5 bar]). The diaphragm will very  
slowly pull onto the air cover. Find the pressure  
that keeps the diaphragm close enough to secure  
with the screws, but does not let it contact the pilot  
pin.  
1. Lubricate and install the shaft u–cup packings  
(402*) so the lips face out of the housing (1). See  
Fig. 13.  
NOTE: Do not deform the diaphragm manually. The  
diaphragm needs uniform pressure to deform properly  
for maximum life.  
2. Assemble the air side plate (104) onto the dia-  
phragm (403). The wide, radiused side of the plate  
must face the diaphragm. Apply medium–strength  
(blue) Loctite or equivalent to the threads of the  
diaphragm assembly. Screw the assembly into the  
shaft (24) hand–tight.  
7. Align the fluid cover (101) and the center housing  
(1) so the arrow (A) faces the same direction as  
the air valve. Secure the cover with two of the  
longer screws (108), handtight.  
NOTE: If the diaphragm contacts the pilot pin and is  
forced away from the air cover, try Step 5 again. If  
necessary, return to Step 3.  
3. Grease the length and ends of the diaphragm shaft  
(24). Insert the shaft/diaphragm assembly into one  
side of the pump. Align the fluid cover (101) and  
the center housing (1) so the arrow (A) faces the  
same direction as the air valve. Secure the cover  
with the screws (107 and 108), handtight.  
8. Torque the longer screws (108) oppositely and  
evenly to 190–220 in–lb (21–25 NSm), using a  
13mm socket wrench. Then torque the shorter  
screws (107). See Torque Sequence, page 32.  
4. Torque the longer screws (108) oppositely and  
evenly to 190–220 in–lb (21–25 NSm), using a

right. The first digit is always D, the second digit is always 0 (zero), and the third is always G. The remaining three  
digits define the materials of construction. Parts included in the kit are marked with an asterisk in the parts list, for  
example (201*).  
For example, if your pump has polypropylene seats, PTFE balls, and PTFE diaphragms, order Repair Kit D 0 G 9  
1 1. If you only need to repair certain parts (for example, the diaphragms), use the 0 (null) digits for the seats and  
balls, and order Repair Kit D 0 G 0 0 1. The digits in the matrix do not correspond to the ref. nos. in the parts  
drawing and lists on pages 28–30.

Graco Warranties  
Graco Standard Husky Pump 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 five years 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 six 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,
