Installation
NOTE: Reference letters and numbers in parentheses in the text refer to callouts in the figures and drawings.
Grounding
Ground all equipment:
•Pump: Use a ground wire and clamp as shown in
FIG. 2.
a. Remove the ground screw (Z) and insert
through the eye of the ring terminal at end of
ground wire (Y).
b. Fasten the ground screw back onto the pump
and tighten securely.
NOTE: To order a ground wire and clamp, order Graco
Part No. 222011.
•Air and fluid hoses: Use only electrically conductive
hoses.
•Air compressor: Follow manufacturer’s recommen-
dations.
•Dispensing valve: Ground through connection to a
properly grounded fluid hose and pump.
•Object being dispensed to: Follow your local code.
•Solvent pails used when flushing: Follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or card-
board, which interrupts the grounding continuity.
•To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the dispens-
ing valve firmly to the side of a grounded metal pail,
then trigger the dispense valve.
Installation Guidelines
Reference letters found in the following instructions,
refer to Typical Installation diagram provided on page 6.
• A ball valve must be installed upstream of the regu-
lator (G).
• The fluid outlet line (A), fluid inlet line (L) and air
inlet line (M) must be flexible (such as a hose).
NOTE: To prevent damage to the pump, remove sedi-
ment from the bottom of the container before installing a
pump on an existing container.
To reduce the risk of static sparking, ground the pump
and all other components used or located in the
dispensing area. Check your local electrical code for
detailed instructions for your area and type of
equipment.

Air Line and Accessories
NOTE: Install the air line accessories in the order shown
in the Typical Installation on page 6.
• Use thread sealant on all male threads except
swivel connections.
• Install a pump runaway valve (D) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.
• Install the air regulator (G) to control pump speed
and pressure.
For NPT models order Graco Part No. 24H420 or for
BSP models order Graco Part No. 24H419.
• Install a bleed-type master air valve (F) upstream
from the pump air regulator (G) but within easy
reach of the pump.
For NPT models order Graco Part No. 110223 or for
BSP models order Graco Part No. 125272.
• On the main air supply line from the compressor,
install an air line filter (H) to remove harmful dirt and
contaminants from the compressor air supply.
Follow Plate - Grease Models Only
For grease models only a follow plate is required for
pumping fluid from the drum. See page 11 for follow
plate installation instructions.
The maximum working pressure of each pump 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 lowest rated component connected to a partic-
ular 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 pressuriza-
tion 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
3A1334P 9
Operation
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 fea-
ture 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. 4. 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 for in-drum
or in-tank applications.
• 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
10 3A1334P
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:
1. A thermal relief event occurs.
2. The air supply valve is closed.
3. 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.
Start-up
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
3A1334P 11
Step 6 is for Oil Pumps Only:
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.
8. When shutting off the system and before checking
or servicing, relieve pressure following pressure
relief procedure, page 9.
Changing Grease Drum and Installing
Follow Plate (grease models only)
1. Relieve pressure, page 9.
2. Remove drum cover by loosening thumb screws (a)
(FIG. 5).
3. Remove pump and cover from drum and place on a
clean paper, cardboard, or clean shop rags. DO
NOT PLACE ON SHOP FLOOR.
4. If this is an existing installation, reach into drum and
pull on follow plate ring (b) to remove follow plate
(FIG. 6). Place follow plate on a clean paper, card-
board or clean shop rags. DO NOT PLACE ON
SHOP FLOOR.
Remove drum and install new one.
5. Examine follow plate to make sure rubber grommet
(c) is in place in center of the plate (FIG. 7).
6. Set follow plate on top of fresh grease (FIG. 8).
Remove air by pushing on the follow plate until the
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.
