306981 5
Installation
Refer to the Typical Installation drawing (Fig. 2).
WARNING
A bleed-type master air valve (D) and a fluid drain
valve (J) are required in your system. These accessories help reduce the risk of serious injury, including skin injection and splashing of fluid in the eyes
or on the skin, and injury from moving parts if you
are adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
Order Part No. 113333.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Order Part No. 238635.
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 23.
Air Line Accessories
Install the following accessories in the order shown in
Fig. 2, using adapters as necessary:
An air line lubricator (C) provides automatic air
motor lubrication.
A bleed-type master air valve (D) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING at left). Be sure the bleed valve is easily
accessible from the pump, and is located down-
stream from the air regulator.
A pump runaway valve (B) senses when the
pump is running too fast and automatically shuts off
the air to the motor. A pump which runs too fast can
be seriously damaged.
An air regulator (E) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the bleed-type master air valve.
An air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
Air and Fluid Hoses
Ensure that you have an adequate compressed air
supply. Refer to the performance chart on page 20 to
find the air consumption of your pump.
Be sure all air and fluid hoses are properly sized and
pressure-rated for your system. Use only electrically
conductive air and fluid hoses. Fluid hoses must have
spring guards on both ends.
Connect an electrically conductive fluid hose (L) to the
pump’s 3/8 npt(f) fluid outlet. Use of a short whip hose
between the main fluid hose (L) and the gun (M) allows
freer gun movement.
Connect a fluid suction hose or tube (N) to the pump’s
3/4 npt(m) fluid intake.
Use an electrically conductive 1/2 in. I.D. (minimum)
air hose (H) to supply air to the pump.
A second bleed-type air valve (G) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 2, using adapters as necessary:
A fluid drain valve (J) is required in your system
to relieve fluid pressure in the hose and gun (see
the WARNING at left). Install the drain valve pointing down, but so the handle points up when the
valve is opened.
A fluid filter (K) filters harmful particles from the
fluid.
A spray gun (M) dispenses the fluid. The gun
shown in Fig. 2 is an airless spray gun.

Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tip.
1. Lock the gun trigger safety.
2. Close the bleed-type master air valve (D, required
in your system). See Fig. 2.
3. Unlock the gun trigger safety.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.
WARNING
MOVING PARTS HAZARD
Do not operate without the air motor
plates (P, Fig. 3) in place. Pinching or
amputation of fingers or hands may
occur. See MOVING PARTS HAZARD
on page 3.
Packing Nut
Keep the packing nut/wet-cup (36) filled with Graco
Throat Seal Liquid (TSL) or compatible solvent, to help
prolong the packing life. See Fig. 3.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
5. Lock the gun trigger safety.
6. Open the drain valve (J, required in your system),
having a container ready to catch the drainage.
7. Leave the drain valve open until you are ready to
spray again.
The packing nut is torqued at the factory and is ready
for operation. If it becomes loose and there is leaking
from the throat packings, relieve pressure, then torque
the nut to 18–20 ft–lb (24–27 N.m). Do this whenever
necessary. Do not overtighten the packing nut.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a
compatible solvent. See Flushing on page 11.
306981 9
Operation
Starting and Adjusting the Pump
See Fig. 2 on page 7. Be sure the air regulator (E)
and bleed-type master air valve (D) are closed. Do not
install the spray tip yet!
Connect a suction hose (N) to the pump’s fluid inlet.
Hold a metal part of the spray gun (M) firmly to the
side of a grounded metal pail and hold the trigger
open. Then open the pump’s bleed-type master air
valve (D). Now slowly open the air regulator until the
pump starts, about 40 psi (0.3 MPa, 3 bar).
Cycle the pump slowly until all the air is pushed out
and the pump and hoses are fully primed. Release the
spray gun trigger and lock the trigger safety. The pump
should stall against pressure when the trigger is released.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
Relieve the pressure. Install the spray tip as explained
in your separate gun manual.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun is opened and closed. In a circulating system, the pump will run continuously and will
speed up or slow down as supply demands until the air
supply is shut off.
Use an adequately sized air regulator (E) to control the
pump speed and the fluid pressure. Always use the
lowest air pressure necessary to get the desired results. Higher pressures waste fluid and cause premature wear of the pump packings and spray tip.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause component rupture and serious injury, never
exceed the Maximum Air Input Pressure marked
on the pump. Refer to the Technical Data on page
20.
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
A pump runaway valve (B), which shuts off the air
supply to the pump if the pump accelerates beyond
the pre-set speed, is available. See Fig. 2 on page
7. Contact your Graco distributor for further information.
10 306981
Shutdown and Care of the Pump
Operation
CAUTION
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
For overnight shutdown, relieve the pressure. Always
stop the pump at the bottom of the stroke to prevent
the fluid from drying on the exposed displacement rod
and damaging the throat packings.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing below.
Flushing
WARNING
FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
AND EXPLOSION HAZARD on page
4. Be sure the entire system and flushing pails are properly grounded. Refer to
Grounding on page 5.
Never leave water or water-base fluid in the pump
overnight. If you are pumping water-base fluid, flush
with water first, then with a rust inhibitor such as
mineral spirits. Relieve the pressure, but leave the
rust inhibitor in the pump to protect the parts from
corrosion.
Model 223586 Shown
P
Flush the pump:
Before the first use
When changing colors or fluids
Before fluid can dry or settle out in a dormant pump
(check the pot life of catalyzed fluids)
Before storing the pump.
Flush with a fluid that is compatible with the fluid you
are pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for
recommended flushing fluids and flushing frequency.
If the pump is being used to supply a circulating system, allow the solvent to circulate until the pump is
thoroughly flushed.
