Installation
General Information
c. Increase the size of the suction piping.
NOTE: Be sure the inlet fluid pressure does not
exceed 25 % of the outlet working pressure.
The Typical Installation shown is only a guide for
selecting and installing system components. Contact
your Graco distributor for assistance in planning a
system to suit your needs. Always use Genuine
Graco Parts and accessories. Be sure all accessories
are adequately sized and pressure rated to meet the
system’s requirements.
3. Reduce liquid velocity: Slow the cyclic rate of
the pump.
Pumped liquid viscosity is also very important but
normally is controlled by factors that are process
dependent and cannot be changed to reduce
cavitation. Viscous liquids are more difficult to pump
and more prone to cavitation.
Reference letters in the text, for example (A), refer to
the callouts in the figures.
Graco recommends taking all the above factors
into account in system design. To maintain pump
efficiency, supply only enough air pressure to the
pump to achieve the required flow.
Variations in color between the plastic components
of this pump are normal. Color variation does not
affect the performance of the pump.
Tighten Fasteners
Graco distributors can supply site specific
suggestions to improve pump performance and
reduce operating costs.
Before mounting and using the pump for the first time,
check and retorque all external fasteners. Follow
Torque Instructions, page 16, or see the torque
tag on your pump. After the first day of operation,
retorque the fasteners.
Mount the Pump
Tips to Reduce Cavitation
Cavitation in an AODD pump is the formation and
collapse of bubbles in the pumped liquid. Frequent
or excessive cavitation can cause serious damage,
including pitting and early wear of fluid chambers,
balls, and seats. It may result in reduced efficiency of
the pump. Cavitation damage and reduced efficiency
both result in increased operating costs.
To avoid serious injury or death from toxic fluid or
fumes:
• Ventilate to a remote area. The pump
exhaust air may contain contaminants. See
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
before moving or lifting the pump.
Cavitation depends on the vapor pressure of the
pumped liquid, the system suction pressure, and the
velocity pressure. It can be reduced by changing any
of these factors.
1. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
1. Reduce vapor pressure: Decrease the
temperature of the pumped liquid.
2. Increase suction pressure:
2. For all mountings, be sure the pump is secured
with screws through the mounting feet.
a. Lower the installed position of the pump
relative to the liquid level in the supply.
3. Make sure the surface is flat and that the pump
doesn’t wobble.
b. Reduce the friction length of the suction
piping. Remember that fittings add friction
length to the piping. Reduce the number of
fittings to reduce the friction length.
4. For ease of operation and service, mount the
pump so air valve, air inlet, fluid inlet and fluid
outlet ports are easily accessible.

Air Lines
Ground The System
1. Install an air filter/regulator assembly (C). The
regulator controls the fluid pressure. The fluid
stall pressure will be the same as the setting of
the air regulator. The filter removes harmful dirt
and moisture from the compressed air supply.
The equipment must be grounded to reduce the
risk of static sparking. Static sparking can cause
fumes to ignite or explode. Grounding provides an
escape wire for the electrical current.
2. Locate a bleed-type master air valve (B) close to
the pump and use it to relieve trapped air. Be
sure the valve is easily accessible from the pump
and located downstream from the regulator.
• Always ground the entire fluid system as
described below.
• Polypropylene and PVDF pumps are not
conductive and are not for use with flammable
fluids.
• Follow your local fire codes.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
Before operating the pump, ground the system as
explained below.
• Pump: Always ground the entire fluid system by
making sure the fluid has an electrical path to a
true earth ground.
3. Locate another master air valve (D) upstream
from all air line accessories and use it to isolate
them during cleaning and repair.
• Air and fluid hoses: Use only grounded hoses
with a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity.
4. Install a grounded, flexible air hose (A) between
the accessories and the 1/2 npt(f) pump air inlet.
• Air compressor: Follow manufacturer’s
recommendations.
• Fluid supply container: Follow local code.
• Solvent pails used when flushing: Follow local
code. Use only conductive metal pails, placed
on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or
cardboard, which interrupts grounding continuity.
Check your system electrical continuity after the
initial installation, and then set up a regular schedule
for checking continuity to be sure proper grounding
is maintained.

3A2888A
Air Exhaust Ventilation
To provide a remote exhaust:
1. Remove the muffler (U) from the pump air
exhaust port (K).
If pumping toxic fluids, you must vent the exhaust
away from people, animals, food handling areas,
and all sources of ignition. Follow all applicable
codes.
2. Install a grounded air exhaust hose (S) and
connect the muffler to the other end of the hose.
The minimum size for the air exhaust hose is 1
in. (26 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.
NOTICE
3. Place a container (T) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.
If the diaphragm ruptures, the fluid being pumped
will exhaust with the air.
The air exhaust port is 1 in. npt(f). Do not restrict
the air exhaust port. Excessive exhaust restriction
can cause erratic pump operation.

Fluid Supply Line
Fluid Outlet Line
1. Connect a grounded, flexible fluid hose (E) to the
1.5 in (38 mm) ANSI/DIN pump fluid inlet flange
1. Connect a grounded, flexible fluid hose (H) to the
1.5 in (38 mm) ANSI/DIN pump fluid outlet flange
2. If the inlet fluid 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. Excessive
inlet fluid pressure also will shorten diaphragm
life. Approximately 3–5 psi (0.02–0.03 MPa,
0.21–0.34 bar) should be adequate for most
materials.
2. Install a fluid drain valve (F) near the fluid outlet.
3. Install a shutoff valve (G) in the fluid outlet line.
3. For maximum suction lift (wet and dry), see
Technical Data, page 22. For best results, always
install the pump as close as possible to the
material source. Minimize suction requirements
to maximize pump performance.

Operation
Pressure Relief Procedure
3. Place the suction tube (if used) in fluid to be
pumped.
Follow the Pressure Relief Procedure
whenever you see this symbol.
NOTE: If fluid inlet pressure to the pump is more
than 25% of outlet working pressure, the ball
check valves will not close fast enough, resulting
in inefficient pump operation.
NOTICE
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
Excessive fluid inlet pressure can reduce
diaphragm life.
4. Place the end of the fluid hose into an appropriate
container.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
5. Close the fluid drain valve.
6. Turn the air regulator knob to 0. Open all
bleed-type master air valves.
3. Open the fluid drain valve to relieve fluid
pressure. Have a container ready to catch the
drainage.
7. If the fluid hose has a dispensing device, hold
it open.
8. Slowly increase air pressure with the air regulator
until the pump just starts to cycle. Allow the
pump to cycle slowly until all air is pushed out of
the lines and the pump is primed.
Tighten Fasteners
Before mounting and using the pump for the first time,
check and retorque all external fasteners. Follow
Torque Instructions, page 16, or see the torque
tag on your pump. After the first day of operation,
retorque the fasteners.
NOTE: Use lowest possible air pressure to prime,
just enough to cycle the pump. If the pump does
not prime as expected, turn air pressure DOWN.
9. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
Flush the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the
pump thoroughly with a compatible solvent. See
10. Close the bleed-type master air valve.
Pump Shutdown
Start and Adjust the Pump
1. Be sure the pump is properly grounded. See
At the end of the work shift and before you check,
adjust, clean, or repair the system, follow the
2. Check fittings to be sure they are tight. Use a
compatible liquid thread sealant on male threads.
Tighten fluid inlet and outlet fittings securely.

3A2888A
Maintenance
Maintenance Schedule
Flushing and Storage
Establish a preventive maintenance schedule
based on the pump’s service history. Scheduled
maintenance is especially important to prevent spills
or leakage due to diaphragm failure.
Lubrication
• Flush before fluid can dry in the equipment, at the
end of the day, before storing, and before repairing
equipment.
The pump is lubricated at the factory. It is designed
to require no further lubrication for the life of the
packings. There is no need to add an inline lubricator
under normal operating conditions.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Tighten Threaded Connections
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
mounting bolts. Check fasteners. Tighten or retorque
as necessary. Although pump use varies, a general
guideline is to retorque fasteners every two months.
• Always flush the pump and relieve the pressure
before storing it for any length of time.
NOTICE
Flush the pump often enough to prevent the
fluid you are pumping from drying or freezing in
the pump and damaging it. Store the pump at
32°F (0°C) or higher. Exposure to extreme low
temperatures may result in damage to plastic parts.

Torque Instructions
If fluid cover or manifold fasteners have been
loosened, it is important to torque them using the
following procedure to improve sealing.
Inlet and Outlet Manifold Screws
NOTE: Fluid cover and manifold fasteners have a
thread-locking adhesive patch applied to the threads.
If this patch is excessively worn, the fasteners may
loosen during operation. Replace screws with new
ones or apply medium-strength (blue) Loctite or
equivalent to the threads.
NOTE: Always completely torque fluid covers before
torquing manifolds.
1. Start all fluid cover screws a few turns. Then, turn
down each screw just until head contacts cover.
2. Turn each screw by 1/2 turn or less working in a
crisscross pattern to specified torque.
3. Repeat for manifolds.
Air Valve Screws and Pilot Valves
Fluid cover and manifold fasteners: 190 to 220
in-lb (21 to 25 Nm)
4. Retorque the air valve fasteners in a crisscross
pattern to the specified torque.
Air valve fasteners: 45 to 55 in-lb (5 to 6 Nm)
5. Retorque the pilot valves to the specified torque.
Do not overtorque.
