General Information
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.
Reference letters in the text, for example (A), refer to
the callouts in the figures.
Variations in color between the plastic components
of this pump are normal. Color variation does not
affect the performance of the pump.
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.
Tips to Reduce Cavitation
c. Increase the size of the suction piping.
NOTE: Be sure the inlet fluid pressure does not
exceed 25 % of the outlet working pressure.
3. Reduce liquid velocity: Slow the cyclic rate of
the pump.

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.
Graco distributors can supply site specific
suggestions to improve pump performance and
reduce operating costs.

n. Viscous liquids are more difficult to pump
one to cavitation.
Mount the Pump
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.
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. Reduce vapor pressure: Decrease the
temperature of the pumped liquid.
2. Increase suction pressure:
a. Lower the installed position of the pump
relative to the liquid level in the supply.
b. Red

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.
• Air and fluid hoses: Use only grounded hoses
with a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity.

Air Exhaust Ventilation
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.
NOTICE
The air exhaust port is 1 in. npt(f). Do not restrict
the air exhaust port. Excessive exhaust restriction
can cause erratic pump operation.
Installation
To provide a remote exhaust:
1. Removethemuffler(U)fromthepumpair
exhaust port (K).
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.
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.

Installation
Fluid Supply L
1. Connect a grounded, flexible fluid hose (E) to the
1.5 in (38 mm) ANSI/DIN pump fluid inlet flange
(L). See Ground The System, page 10.
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.
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.
ine
Fluid Outlet L
1. Connect a grounded, flexible fluid hose (H) to the
1.5 in (38 mm) ANSI/DIN pump fluid outlet flange
(M). See Ground The System, page 10.
2. Install a fluid drain valve (F) near the fluid outlet.
3. Install a shutoff valve (G) in the fluid outlet line.

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.
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.

Lubrication
The pump is lubricated at the factory. It is designed
to require no further lubrication for the life of the

under normal operating conditions.
Tighten T
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.
See Torque Instructions, page 16.
hreaded Connections
Flushing and Storage
• Flush before fluid can dry in the equipment, at the
end of the day, before storing, and before repairing
equipment.
• 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.
• 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.
