The maximum working pressure of each component in your
system may not be the same. To reduce the risk of
over-pressurizing any part of your system, which may result
in component rupture, fire or explosion and cause serious
bodily injury, be sure you know the maximum working
pressure rating of each pump and its connected
components.
•Never exceed the maximum working pressure of the low-
est rated component connected to a particular pump.
•Be sure you know the maximum working pressure of
each component.
•Do not exceed the maximum pump cycle rate.
•Regulate air pressure to prevent over pressurization at
fluid section of the pump.
•Regulate air pressure to the pump so that no fluid line
component or accessory is over pressurized.
NOTICE
Do not hang the air accessories directly on the air inlet.
Mount them on brackets. Always use a flexible hose
between all connections. The air inlet is not strong enough
to support accessories and may cause one or more to
break.

Operation
Additional operating instructions, related warnings and
technical data for are provided in the individual compo-
nent instruction manuals included with your system.
Thermal Induced Pressure Relief
(Oil pumps only)
Thermal Relief Theory of Operation
The pump operation is similar to most double acting
reciprocating pumps. The pump only comes to a com-
plete stop on the up stroke. The pump will stroke
through on the down stroke due to the inlet check relief
passage.
Excess pressure due to downstream thermal expansion
causes the air motor/pump to run backwards (down-
ward). Fluid pressure is relieved through the inlet check
relief passage as the pump piston moves downward. Air
pressure is simultaneously relieved through the air inlet
passage. The pump piston moves downward exposing
the pump cylinder relief passage at the bottom of the
stroke. Additional excess pressure is then relieved
through both the inlet check relief passage and the
pump cylinder relief passage.
Pressure is relieved at the pump through the pump inlet
relief passage. The pump will not change over on the
bottom of the stroke as a result of relieving excess pres-
sure due to the positioning of the pump cylinder groove
with respect to the air motor pilot valve.
NOTE:
• The air supply does not have to be turned off to
enable thermal relief activation.
• The thermal induced pressure relief design feature
of the pump will cause the pump to dive on the
downstroke when a dispensing valve is closed.
THERMAL EXPANSION HAZARD
Fluids subjected to heat in confined spaces, including
hoses, can create a rise in pressure due to the
thermal expansion. Over-pressurization can result in
equipment rupture and serious injury.
Oil pumps have a built-in, thermal induced, pressure
relief as shown in FIG. 3. To ensure system pressure
will automatically bleed excess thermal induced
system pressure through the pump and back to the
oil reservoir:
• Always use a relieving air pressure regulator to
allow the pump/motor to run backwards. The regu-
lator bleeds excess air pressure.
• There should not be any obstructions between air
inlet of pump and regulator.
• There should not be any obstructions between the
downstream plumbing and pump outlet such as
closed ball valves or check valves.
• There should not be any obstructions between the
pump inlet and fluid container such as closed ball
valves or check valves.
• Only use Graco designed suction tubes with a
built-in relief device for wall mount applications.
• Always use an inlet screen to prevent debris from
plugging relief passages from entering the pump.
- Do not operate the pump with out an inlet screen.
• Periodically inspect the inlet screen for plugging.
Graco recommends inspecting the inlet screen
every time the container is changed out.

Operation
3A1335K 7
Install only one pump per delivery system. Do not use the
pumps in a parallel pump installation.
Loss of pump prime can occur if all the following events occur
in sequence:
a. A thermal relief event occurs.
b. The air supply valve is closed.
c. A dispense valve located at an elevation higher
than the tank level, is open.
To prevent loss of prime, ensure the air supply valve is turned
on before attempting to dispense fluid.
Pressure Relief Procedure
1. Close the pump’s bleed-type master air valve.
2. Close the pump air regulator and disconnect the air
supply hose.
3. Open the dispensing valve and dispense fluid into a
waste bucket/container until pressure is fully
relieved.
If you suspect that the dispensing valve is clogged, or
that pressure has not been fully relieved after following
the steps above, very slowly loosen the dispensing
valve coupler or hose end coupling to relieve pressure
gradually, then loosen completely.
Determining Output Pressure Using the Air
Regulator
To determine the fluid output pressure using the air reg-
ulator reading, multiply the ratio of the pump by the air
pressure shown on the regulator.
For example a 3:1 ratio oil pump:
3:1 ratio x 100 psi air = 300 psi fluid outlet
A 3:1 pump is capable of 5:1 on the downstroke and will
develop 5:1 pressures under normal operation.
A grease pump has a ratio of 50:1. However it is capable
of reaching a stall pressure equal to 60 times the air
input pressure. To calculate the fluid output pressure
using the air regulator reading, multiply the regulator
gauge by 60.
For example:
140 psi air x 60 = 8400 psi fluid output
0.97 MPa air x 60 = 58.2 MPa
99.7 bar x 60 = 582 bar
Regulate air to the pump so that no air line or fluid line
component or accessory is over pressurized.
Priming the Pump
1. Close the air regulators and bleed-type master air
valves to all but one pump.
2. Open the master air valve from the compressor.
3. For the pump that is connected, trigger the dispens-
ing valve into a grounded metal waste container
making firm, metal-to-metal contact between the
container and the valve.
4. Slowly open the bleed-type master air valve and
open the pump air regulator just until the pump is
running. When the pump is primed and all air has
been pushed out of the lines, release the trigger.
5. If you have more than one pump, repeat this pro-
cess for each pump in your system.
NOTE: When the pump is primed and has sufficient
air supplied to it, it starts when the dispensing valve
is open and shuts off when closed.
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious injury
from pressurized fluid, fluid from the valve, or splash-
ing fluid, follow this procedure whenever you:
• are instructed to relieve pressure
• stop dispensing
• check, clean, or service any system equip-
ment
• install or clean dispensing devices.

Operation
83A1335K
6. The thermal relief feature of this oil pump can
increase the amount of time needed to fully prime
the pump when compared to pumps without a ther-
mal relief feature. To minimize this effect, prime the
pump before connecting it to an already primed dis-
tribution system.
7. Read and follow the instructions supplied with each
component in your system.
Startup
1. Turn air supply on. Pump will pressurize the system.
2. Trigger dispense valve to control the pump’s on/off
operation.
3. When shutting off the system and before checking
or servicing, relieve pressure following pressure
relief procedure, page 7.
NOTICE
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. If your pump acceler-
ates quickly, or is running too fast, stop it immediately
and check the fluid supply. If the supply container is
empty and air has been pumped into the lines, prime
the pump and lines with fluid, or flush it and leave it
filled with a compatible solvent. Be sure to eliminate
all air from the fluid system.
NOTE: A pump runaway valve can be installed on the
air line to automatically shut off the pump if it starts to
run too fast.
