WARNING
HAZARDOUS FLUIDS
Improper handling of hazardous fluids or inhaling toxic vapors can cause extremely serious injury or
death from to splashing in the eyes, ingestion, or bodily contamination. Observe all the following
precautions when handling known or potentially hazardous fluids.
D Know what fluid you are pumping and its specific hazards. Take precautions to avoid a toxic fluid
spill.
D Always wear appropriate clothing and equipment, such as eye protection and breathing appara-
tus, to protect yourself.
D Store hazardous fluid in an appropriate, approved container. Dispose of it according to all Local,
State and Federal guidelines for hazardous fluids.
D Secure the fluid outlet hose tightly into the receiving container to prevent it from coming loose
and improperly draining the fluid.
D Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas.
If the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on
page 7.
FIRE AND EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose. If the equipment is not
properly grounded, sparking may occur. Sparks can ignite fumes from solvents and the fluid being
pumped, dust particles, and other flammable substances, whether you are pumping indoors or
outdoors, and can cause a fire or explosion and serious injury and property damage.
D To reduce the risk of static sparking, ground the pump and all other equipment used or located in
the work area. Check your local electrical code for detailed grounding instructions for your area
and type of equipment. Refer to Grounding on page 4.
D If you experience any static sparking or even a slight shock while using this equipment, stop
pumping immediately. Check the entire system for proper grounding. Do not use the system
again until the problem has been identified and corrected.
D Pipe and dispose of the exhaust air safely, away from all sources of ignition. If the diaphragm
fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on page 7.
D Do not smoke in the work area. Do not operate the equipment near a source of ignition or an
open flame, such as a pilot light.
HALOGENATED HYDROCARBON HAZARD
Never use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents in aluminum pumps. Such use could result in a serious chemical
reaction, with the possibility of explosion, which could cause death, serious injury, and/or substantial
property damage.
Consult your fluid suppliers to ensure that the fluids used are compatible with aluminum parts.
United States Government safety standards have been adopted under the Occupational Safety and Health Act.
You should consult these standards—particularly the General Standards, Part 1910, and the Construction
Standards, Part 1926.

Grounding
WARNING
ELECTRIC SHOCK HAZARD
This pump must be grounded. The
steps for grounding may differ from the
way you ground other pumps. Read and
carefully follow the grounding instructions below
before you operate the pump.
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment.
Ground all of this equipment:
D Pump: Connect a ground wire and clamp as shown
in Fig. 1. Loosen the grounding lug locknut (W)
and washer (X). Insert one end of a 12 ga (1.5
mm@) minimum ground wire (Y) into the slot in the
lug (Z), and tighten the locknut securely. Connect
the clamp end of the ground wire to a true earth
ground. To order a ground wire and clamp, order

CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if contaminants could
affect your fluid supply. See Air Exhaust Ventila-
tion on page 7.
D Be sure the mounting can support the weight of the
pump, hoses, and accessories, as well as the
stress caused during operation.
D For all mountings, be sure the pump is secured with
screws through the mounting feet (58). See the
mounting feet in the Parts Drawing on page 22.
Air Line
WARNING
A bleed-type master air valve and a fluid drain
valve are required on your system.
The bleed-type master air valve relieves air
trapped between itself and the pump. Trapped air
can cause the pump to cycle unexpectedly, which
could result in serious bodily injury, including
splashing in the eyes, injury from moving parts, or
contamination from hazardous fluids.
The fluid drain valve reduces the risk of serious
bodily injury, including splashing in the eyes or on
the skin, or contamination from hazardous fluids.
Install the fluid drain valve close to the pump’s
fluid outlet to relieve pressure in the hose if the
hose becomes plugged.
2. Install a flexible air hose between the accessories
and the pump air inlet. Screw the air line fitting
into the air inlet.
3. Do not restrict the exhaust port. Excessive
exhaust restriction can cause erratic pump
operation.
Fluid Lines
WARNING
Graco always recommends that you use grounded
fluid hoses to dissipate static electricity. When
pumping non-conductive flammable fluids, grounded fluid hoses are required. See Fire and Explo-
sion Hazard on page 3.
Fluid Outlet Line
1. Attach the fluid outlet hose to the fluid outlet flange
by using a 3-in. ANSI or DIN flanged hose or pipe.
2. Install a fluid drain valve near the fluid outlet. See
the WARNING in the Air Line section at left.
Fluid Suction Line
Attach the fluid suction hose to the pump fluid inlet
flange by using a 3-in. ANSI or DIN flanged fluid
suction hose or pipe.
D If the inlet pressure to the pump is more than 25
percent of the outlet working pressure, the ball
check valves do not close fast enough, which
results in inefficient pump operation.
D At inlet fluid pressures over 15 psi (100 kPa, 1.0
bar), diaphragm life is shortened.
1. Mount the air line accessories on the wall or on a
bracket. Be sure the air line supplying the
accessories is grounded.
a. The pump speed can be controlled in one of
two ways: To control it on the air side, install
an air regulator. To control it on the fluid side,
install a fluid valve near the outlet.
b. Install a bleed-type master air valve
downstream from the air regulator, and use it
to relieve trapped air. See the WARNING,
above. Locate another bleed-type master air
valve upstream from all air line accessories,
and use it to isolate the accessories during
cleaning and repair.
c. The air line filter removes harmful dirt and
moisture from the compressed air supply.
6 308639
D The maximum suction lift is 8 ft (2.5 m) of water dry
or 28 ft (8.5 m) of water wet. For suction lifts
between 8 ft (2.5 m) and 28 ft (8.5 m) of water, it is
necessary to install a foot valve, and it is necessary
to flood the suction to prime the pump. The pump
may prime better if you reduce the inlet air pressure
until the pump is primed.
Installation
Air Exhaust Ventilation
Changing Manifold Orientation
(See Fig. 6 on page 14)
The outlet manifold (50) and inlet manifold (53) can be
rotated to best suit your installation needs. The pump
is shipped with the inlet and outlet facing in the same
direction.
1. Remove the screws (54) from each end of the
manifold (50 or 53).
2. Turn the manifold to the desired position, and
reinstall the screws (54). Torque to 55 to 60 ft-lb
(75 to 81 NSm). See Torque Sequence, page 25.
NOTE: To ensure proper seating, visually check
that the manifold is centered on the fluid covers
(51) before you tighten the screws (54).
Fluid Pressure Relief Valve
CAUTION
Some systems may require installation of a pressure relief capability at the pump outlet to prevent
overpressurization and rupture of the pump or
hose.
Thermal expansion of fluid in the outlet line can
cause overpressurization if the fluid line is close
ended. Such overpressurization can occur when
using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm
area (for example, from an underground tank).
WARNING
TOXIC FLUID HAZARD
Be sure to read and follow the USING
HAZARDOUS FLUIDS, and FIRE OR
EXPLOSION HAZARD warnings on
page 3, before you operate this pump.
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 or food handling
areas when pumping flammable or
hazardous fluids.
The minimum size for the air exhaust hose is1 in.
(25.4 mm) ID x 5 ft. (1.5 m). If a longer hose is
required, use a larger diameter hose. Avoid sharp
bends or kinks in the hose.
If the diaphragm ruptures, the fluid being pumped
will be exhausted with the air. Place a container at
the end of the air exhaust line to catch fluid in case
the diaphragm ruptures.
The air exhaust port is 1 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
To provide a remote exhaust:
1. Remove the muffler (60) from the pump air
exhaust port.
2. Install a grounded air exhaust hose (T) and
connect the muffler (60) to the other end of the
hose. The minimum size for the air exhaust hose
is 1 in. (25.4 mm) ID x 5 ft (1.5 m). If a longer
hose is required, use a larger diameter hose.
Avoid sharp bends or kinks in the hose. See
Fig. 3.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.

Operation
Pressure Relief Procedure
WARNING
To reduce the risk of serious injury, including
splashing fluid in the eyes or on the skin, follow this
procedure whenever you are instructed to relieve
pressure, when you shut off the pump, and before
you check, adjust, clean, move, or repair any
system equipment.
1. Shut off the air to the pump.
2. Open any available outbound fluid valves to relieve
fluid pressure from the pump.
3. If fluid is still in the outbound fluid lines, isolate this
fluid as follows:
a. Close the outbound fluid valves.
b. Slowly remove the fluid connections from the
pump, and have a container ready to catch
any fluid that runs out.
Flush the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush it
thoroughly with a compatible solvent. Follow the
procedure in Starting and Adjusting the Pump.
3. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: If the inlet pressure to the pump is more
than 25 percent of the outlet working pressure, the
ball check valves will not close fast enough,
resulting in inefficient pump operation.
4. Place the end of the outlet hose into an
appropriate container.
5. Close the fluid drain valve.
6. With the air regulator closed, open all bleed-type
master air valves.
7. If the outlet hose has a dispensing device, hold it
open while continuing with step 8.
8. Slowly open the air regulator 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.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses, close the
air regulator, and remove the suction hose from
the solvent and place it in the fluid to be pumped.
If you are shutting down the pump, remove the
suction hose from the fluid container, run the pump
until the fluid is forced out of the system, and shut
off the air supply immediately.
If you are going to use the pump, start the pump
again, and place the suction hose in the supply
container.
Starting and Adjusting the Pump
WARNING
To reduce the risk of serious injury, splashing in
the eyes or on the skin, and toxic fluid spills,
never move or lift a pump under pressure. If the
pump is dropped, the fluid section could rupture.
Always follow the Pressure Relief Procedure
above before you move or lift the pump.
1. Be sure the pump is properly grounded. Read and
follow the instructions in Grounding on page 4.
2. Check all fittings to be sure they are tight. Be sure
to use a compatible liquid thread sealant on all
male threads.
Pump Shutdown
At the end of the work shift and before checking,
adjusting, cleaning, or repairing the system, relieve
the pressure.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
9308639
Maintenance
Lubrication
The air valve is designed to operate unlubricated.
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.
CAUTION
Do not over-lubricate the pump. Excess oil is exhausted through the muffler, which could contaminate your fluid supply or other equipment.
Flushing and Storage
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Always flush the pump and relieve the
pressure before storing it for any length of time. Use
a compatible solvent.
WARNING
Tightening Connections
Before each use, check all hoses for wear or damage,
and replace them as necessary. Check to be sure all
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 25.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based
on the pump’s service history. This is especially
important for prevention of spills or leakage due to
diaphragm failure.
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.

3. Using a 15-mm socket wrench, remove the
screws (54), and pull the fluid covers off the pump.
See Fig. 7.
For steps 4 to 9, see Fig. 8.
Reassembly (See Fig. 8)
1. Install each u-cup seal (15) so the lips face away
from the center of the pump. Lubricate the u-cup
seals.
2. Install a diaphragm assembly on one end of the
shaft (14) as follows:
a. Place a washer (63) and then a white o-ring
(64) on the diaphragm bolt (62). The o-ring
may fit very snugly on the bolt. Insert the bolt
into the fluid-side diaphragm plate (52) as
shown in Fig. 8. Grease the bolt threads.
b. Lay the diaphragm (301) into the grooves on
the fluid-side diaphragm plate (52) so that the
side marked AIR SIDE faces the center of the
pump.
For models with bolt–through PTFE
diaphragms, also install the shim (302) and
back-up diaphragm (303), as shown in Fig. 8.
Line up diaphragm tabs with tabs on air cover.
The bolts must go through the bolt–through
PTFE diaphragm.
4. Using 15/16-in. wrenches or sockets, loosen but
do not remove one of the diaphragm plate bolts
(62). (whichever one turns)
5. Remove the fluid-side plate (52), diaphragm (301),
and air-side plate (57).
For models with PTFE diaphragms, also remove
the shim (302) and back-up diaphragm (303).
6. Pull the other diaphragm assembly and the
diaphragm shaft (14) out of the center housing (2).
Hold the shaft flats with a 7/8-in. wrench, and
remove the remaining fluid-side plate (52) from the
shaft. Disassemble the remaining diaphragm
assembly.
7. Inspect the diaphragm shaft (14) for wear or
scratches. If it is damaged, inspect the bearings
(13) in place. If the bearings are damaged, see
Removing and Replacing Bearings and Air
Gasket on page 18.
8. Reach into the center housing (2) with an o-ring
pick, and hook the u-cup seals (15), then pull them
out of the housing. This can be done with the
bearings (13) in place.
9. Clean all parts and inspect for wear or damage.
Replace parts as needed.
c. Place the air-side diaphragm plate (57) and
washer (63) over the bolt. Screw the shaft
(14) onto the bolt handtight.
3. Grease the length of the shaft (14), and slide it
through the center housing (2).
4. Assemble the other diaphragm assembly to the
shaft as explained in step 2.
Step 5 is easiest if the pump is mounted vertically in a
vise.
5. Torque the bolts (62) to 100 to 120 ft-lb (136 to
163 NSm).
WARNING
Failure to properly torque the diaphragm bolts (62)
could result in a bolt failure. If a diaphragm bolt
fails, fluid is exhausted through the muffler. See
Air Exhaust Ventilation on page 7.
6. Install the fluid cover screws (54) hand tight.
Torque the screws to 55 to 60 ft-lb (75 to 81 NSm)
in a crossing pattern. See Fig. 7. See Torque
Sequence, page 25.
7. Reassemble the ball check valves and manifolds
as explained on page 14.
