Air Exhaust Ventilation
Be sure to read and follow the TOXIC FLUID
OR FUMES HAZARD warnings, page 7, and
FIRE AND EXPLOSION HAZARD warnings,
page 5, before operating this pump. You must
vent the exhaust away from people, animals,
food handling areas, and all sources of ignition when pumping flammable or hazardous
fluids. Vent in accordance with local codes, or
in the absence of local codes, an industry or
nationally recognized code having jurisdiction
over the specific installation.
The air exhaust port is 3/4 npt(f). Do not
restrict the air exhaust port. Excessive exhaust
restriction can cause erratic pump operation.
1. Remove the muffler (T) from the pump air
exhaust port.
2. Install a grounded air exhaust hose (U) and
connect the muffler (T) 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.
3. Place a container at the end of the air
exhaust line to catch fluid in case a diaphragm ruptures. Locate the container
away from all sources of ignition, including
pilot lights and waste materials. If the diaphragm ruptures, the fluid being pumped
will exhaust with the air.

Fluid Pressure Relief Valve
Fuel Dispense Systems (Model 647648)
Fuel dispense model 647648 requires a pressure relief valve (S), Graco part 24B910,
which is supplied with the pump, to prevent
fluid pressure from exceeding 50 psi (350 kPa,
3.5 bar). See FIG. 5, page 13.
Recommended air operating pressure is 40
psi (280 kPa, 2.8 bar) or less. As the air inlet
pressure approaches 50 psi (350 kPa,
3.5 bar), the relief valve will open and vent
fluid. Vented fluid must be routed to a container in a non-hazardous location.
Evacuation and Transfer Systems (Model 647016)
Some evacuation and transfer systems may
require installation of a pressure relief valve at
the pump outlet to prevent overpressurization
and rupture of the pump or hose. Graco Kit
238428 is available. See FIG. 6. Relief pressure is between 150 and 180 psi (1.03

more than 25% of outlet working pressure, the
ball check valves will not close fast enough,
resulting in inefficient pump operation.
7. Slowly increase air pressure with 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.
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.

based on the pump’s service history. Scheduled maintenance is especially important to
prevent spills or leakage due to diaphragm
failure.
Lubrication
The pump is lubricated at the factory. It is
designed to require no further lubrication for
the life of the pump. There is no need to add
an in-line lubricator under normal operating
conditions.
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 fasteners. Tighten or retorque
as necessary. Although pump use varies, a
general guideline is to retorque fasteners every
two months. See Torque Instructions,
page 18.
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.
Flush the pump often enough to prevent the
fluid you are pumping from drying or freezing
in the pump and damaging it. Use a compatible solvent.
Always flush the pump and relieve the pressure before storing it for any length of time.

Maintenance
Torque Instructions
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.
If fluid cover or manifold fasteners have been
loosened, it is important to torque them using
the following procedure to improve sealing.
NOTE: Always completely torque fluid covers
before torquing manifolds.
Start all fluid cover screws a few turns. Then
turn down each screw just until head contacts
cover. Then turn each screw by 1/2 turn or less
working in a crisscross pattern until each
screw is torqued to 100 in-lb (11.3 N•m).
Repeat for manifolds. See FIG. 7.
Retorque the air valve fasteners (V) in a
crisscross pattern, to 80 in-lb (9.0 N•m).
