The Typical Installation above is only a guide to
selecting and installing accessories For assistance in
designing a system to meet your needs, contact your
Graco distributor
The Dimensional Drawings on page 25 provide
necessary measurements for installing the pump on a
custom designed mounting
System Accessories
Refer to the Typical Installation drawing, above for
assistance in setting up your system If you supply
your own accessories, be sure they are adequately
sized to meet the system’s requirements If your pump
is mounted in a ram or elevator, refer to the manual
supplied with it for installation and operation
instruc-tions
Install the accessories in the order shown in the
Typi-cal Installation drawing The pump runaway valve (R)
senses when the pump is running too fast and shuts
off the air supply to the motor The air line lubricator
(F) provides automatic air motor lubrication The
bleed–type master air valve (G) relieves air trapped
between it and the pump when it is closed Be sure the
valve is easily accessible from the pump The air
regulator (H) controls pump speed and outlet pressure
The air line filter (E) removes harmful dirt and moisture
from the compressed air supply
WARNING
A bleed-type master air valve (G) and a fluid drainvalve (J) are required in your system These acces-sories help reduce the risk of serious injury includ-ing fluid injection, splashing in the eyes or on theskin, and injury from moving parts if you are adjust-ing or repairing the pump
The bleed-type master air valve relieves air trappedbetween this valve and the pump after the air isshut off Trapped air can cause the pump to cycleunexpectedly Position the valve close to thepump
The fluid drain valve assists in relieving fluid sure in the displacement pump, hose, and spraygun; triggering the spray gun to relieve pressuremay not be sufficient
pres-Using a suitable adapter, connect a fluid drain valve (J)near the 1 in npt(f) fluid outlet of the pump Thenconnect a grounded fluid supply hose (K) For moreflexible spray gun movement, use a shorter 13 mm(1/2 in.) ID hose (L) between the spray gun and themain hose
Trang 8Operation Pressure Relief Procedure
WARNING
INJECTION HAZARD
Fluid under high pressure can be
in-jected through the skin and cause
seri-ous injury To reduce the risk of an injury
from injection, splashing fluid, or moving parts,
fol-low the Pressure Relief Procedure whenever you:
are instructed to relieve the pressure,
stop spraying/dispensing,
check or service any of the system equipment,
or install or clean the spray tips/nozzles
1 Lock the gun/valve trigger safety
2 Shut off the air to the pump
3 Close the bleed-type master air valve (required in
your system)
4 Unlock the gun/valve trigger safety
5 Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure
6 Lock the gun/valve trigger safety
7 Open the drain valve and/or the pump bleeder
valve (required in your system), having a container
ready to catch the drainage
8 Leave the drain valve open until you are ready to
dispense again
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 relievepressure gradually, then loosen completely, then clearthe tip or hose
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate yourfingers or other body parts When thepump is operating, the priming piston (Q)(located at the pump intake) and the air motor pis-ton (located behind the air motor shield) move.Therefore, never operate the pump with the air mo-tor shield removed, and keep your fingers andhands away from the priming piston
Before attempting to clear an obstruction from thepriming piston (Q) or service the pump, follow the
Pressure Relief Procedure at left to prevent the
pump from starting accidentally
Flush the Pump Before Using
The pump is tested with lightweight oil, which is left in
to protect the pump parts If the fluid you are usingmay be contaminated by the oil, flush it out with acompatible solvent before using the pump
Keep the wet-cup (136) one-half full with Graco ThroatSeal Liquid (TSL), to help prevent the fluid beingpumped from drying on the displacement rod anddamaging the packings Do not use TSL with food orsanitary applications
WARNING
For your safety, read the warning section Fire or
Explosion Hazard on page 4 before flushing, and
follow all recommendations given there
Trang 9Operation Starting and Adjusting the Pump
1 Make sure the air regulator (H) is closed
2 Open the bleed–type master air valve (G)
3 Hold a metal part of the spray gun firmly to the
side of a grounded metal pail and hold the trigger
open Now slowly open the air regulator until the
pump starts See the Typical Installation on page
7
4 Cycle the pump slowly until all the air is pushed
out and the pump and hoses are fully primed
5 Release the spray gun trigger and engage the
safety latch The pump will stall against pressure
when the trigger is released
6 If the pump fails to prime properly, open the
bleed-er valve plug (139) slightly Use the bleedbleed-er hole
(P) on the underside of the valve body (138) as a
priming valve until the fluid appears at the hole
See Fig 3
7 Close the bleeder valve plug (139)
WARNING
To reduce the risk of fluid injection, do not use your
hand or fingers to cover the bleeder hole when
priming the pump
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
Use the air regulator to control the pump speed and
the fluid pressure Always use the lowest air pressure
necessary to get the desired results Higher pressures
cause premature tip/nozzle and pump wear
WARNING
To reduce the risk of overpressurizing your system,which could result in component rupture and causeserious bodily injury, never exceed 0.7 MPa, 7 bar(100 psi) incoming air pressure to the pump
Fig 3
136P

Q138
Never allow the pump to run dry of the fluid beingpumped A dry pump will quickly accelerate to a highspeed, possibly damaging itself A pump runawayvalve, which shuts off the air supply to the pump if thepump accelerates beyond the pre–set speed, is avail-able
If your pump accelerates quickly, or is running too fast,stop it immediately and check the fluid supply If thesupply container is empty and air has been pumpedinto the lines, refill the container and prime the pumpand the lines with fluid, or flush and leave it filled with acompatible solvent Be sure to eliminate all air fromfluid system
Trang 10Operation Shutdown and Care of the Pump
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
For overnight shutdown, follow the Pressure Relief
Procedure on page 8 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
Every 40 hours of operation, check that the packing
nut/wet cup is tight Follow the Pressure Relief
Pro-cedure and tighten the nut just snug – do not
overtigh-ten, or the packings may be damaged
Flushing
To reduce the risk of fluid injection injury, static
spark-ing, or splashing in the eyes or on the skin, relieve the
pressure, and remove the spray tip (spray guns or
spray valves only) before flushing Hold a metal part ofthe gun/valve firmly to the side of a grounded metalpail and use the lowest possible fluid pressure duringflushing
Always flush the pump before the fluid dries on thedisplacement rod Never leave water or water–basedfluid in the pump overnight First, flush with water or acompatible solvent, then with mineral spirits Relievethe pressure, but leave the mineral spirits in the pump
to protect the parts from corrosion
Lubrication
The accessory air line lubricator (F) provides automaticair motor lubrication For daily manual lubrication,disconnect the air supply, place about 15 drops of lightmachine oil in the pump air inlet, and reconnect the airsupply to blow oil into the motor
