Notes
Installation
(All Pumps)
Typical Installation
The T
ypical Installations shown in Figs. 2 and 3, and
the following installation information are only guides.
Proper sizing of the pump, accessories and lines is
essential to get the maximum performance from your
system. Contact your Graco distributor for assistance
in designing a system to meet your needs.
Mount the Pump
This
pump can be mounted on a floor stand, cart, wall
bracket, or drum. The floor stand shown in the T
ypical
Installation is Part. No. 220–581.
Instructions for mounting the pump are supplied with
the mounting accessory
.
Plumbing
The pump has a 1–1/2 in. npt(f) fluid inlet and a 1 in.
npt(f) fluid outlet. Use a minimum 25 mm (1 in.) diame
-
ter pipe or hose between the pump outlet and any
supply line accessories. Use a minimum 38 mm (1–1/2
in.) diameter pipe or hose between the mix tanks and
pump inlet.
When using a stainless steel pump, use stainless steel
plumbing to maintain a corrosion-resistant system.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below
. Also read
the section
FIRE AND EXPLOSION
HAZARD
on page 5.
1.
Pump:
use the ground wire and clamp. See Fig. 1.
Loosen the grounding lug locknut (W) and washer
(X). Insert one end of a 12 ga (1.5 mm
) minimum
ground wire (Y) into the slot in lug (Z) and tighten
the locknut securely
. Connect the other end of the
wire to a true earth ground. For a ground wire and
clamp, order Part No. 237–569.

2.
Air and fluid hoses:
use only electrically conductive
hoses.
3.
Air compressor or hydraulic power supply:
follow
manufacturer’
s recommendations.
4.
Surge tank:
use a ground wire and clamp.
See Fig. 1.
5.
Spray gun:
ground through connection to a prop
-
erly grounded fluid hose and pump.
6.
Fluid supply container:
follow your local code.
7.
Object being sprayed:
follow your local code.
8.
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
cardboard, which interrupts the grounding continu
-
ity.
9.
T
o maintain grounding continuity when flushing or
relieving pressure
, hold a metal part of the spray
gun firmly to the side of a grounded
metal
pail,
then trigger the gun.
Installation
(Air-Powered Pumps)
Air Line to Motor
WARNING
A
bleed-type master air valve (D) is required in
your system, to help reduce the risk of serious
injury including splashing fluid in the eyes or on the
skin, and injury from moving parts if you are adjust
-
ing or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut of
f. T
rapped air can cause the pump to cycle
unexpectedly
. Locate the valve close to the pump.
Order Part No. 1
13–333.
1.
The air line lubricator (N) automatically lubricates
the air motor to prevent corrosion. See Fig. 2.
2.
The bleed-type master air valve (M) relieves air
trapped between itself and the motor
, when the
valve is closed. Install one valve close to the
pump, downstream from the air regulator
. Install a
second bleed valve upstream from all other air line
accessories, to isolate the accessories for servic
-
ing.
3.
The air regulator (L) controls pump speed.
4.
The pump runaway valve (P) shuts of
f the air to
the pump if the pump speed exceeds your pre-ad
-
justed setting. Running a pump too fast can dam
-
age it.
5.
The air filter (K) removes harmful dirt and moisture
from the compressed air supply
.
6.
The air supply line (J) must be large enough to
supply the proper volume of air to the motor
.
Fluid Line from Pump
WARNING
A
fluid drain valve (J) is required in your system, to
help reduce the risk of serious injury including
splashing in the eyes or on the skin if the pump
cycles unexpectedly
.
Locate one valve downstream from the pump outlet
and another valve downstream from the surge tank
(G). These drain valves are used to relieve fluid
pressure in the pump and surge tank during shut
-
down.
1.
The surge tank (G) reduces fluid surging to pre
-
vent backflow into the pump. Mounting instructions
are supplied with the tank.
2.
The shutoff valves (D) before and after the surge
tank, and between each mix tank and the pump
fluid inlet, isolate these components for servicing.
3.
Be sure the supply line (C) between the pump and
mix tanks is level.

Hydraulic Power Supply
CAUTION
The
Hydraulic Power Supply must be kept clean at
all times to avoid damage to the motor and hydraulic
power supply
.
1.
Blow out hydraulic lines with air and flush thor
-
oughly before connection to the motor
.
2.
Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.
1.
Be sure the power supply can provide suf
ficient
power to the motor
.
2.
Be sure the power supply is equipped with a
suction filter to the hydraulic pump.
Hydraulic Supply to Motor
NOTE:
The motor’
s hydraulic inlet is 3/4 in., 37
flare.
Use a minimum 13 mm (1/2 in.) ID hydraulic supply
line (L).
1.
The shutof
f valve (R) isolates the motor when
servicing the system. See Fig. 3.
2.
The hydraulic fluid pressure gauge (Q) monitors
the hydraulic oil pressure to the motor
. This helps
avoid overpressurizing the motor or displacement
pump.
3.
The pressure- and temperature-compensated flow
control valve (S) prevents the motor from running
too fast, which can damage it.
4.
The pressure reducing valve (P) which has a drain
line (M) running to the return line (K), controls the
hydraulic pressure to the motor
.
Hydraulic Return from Motor
NOTE: The motor’
s hydraulic outlet is 7/8 in., 37
flare. Use a minimum 16 mm (5/8 in.) ID hydraulic
return line (K).
1.
The shutof
f valve (R) isolates the motor when
servicing the system.
CAUTION
T
o avoid damage to the pump, never use the return
line shutof
f valve to control the hydraulic flow
. Do not
install any flow control devices on the hydraulic re
-
turn line.
2.
The 10 micron size return filter (J) removes resi
-
due from the hydraulic fluid to help keep the sys
-
tem running smoothly
.
Fluid Line from Pump
WARNING
A
fluid drain valve (J) is required in your system, to
help reduce the risk of serious injury including
splashing in the eyes or on the skin if the pump
cycles unexpectedly
.
Locate one valve downstream from the pump outlet
and another valve downstream from the surge tank
(G). These drain valves are used to relieve fluid
pressure in the pump and surge tank during shut
-
down.
1.
The surge tank (G) reduces fluid surging to pre
-
vent backflow into the pump. Mounting instructions
are supplied with the tank.
2.
The shutoff valves (D) before and after the surge
tank, and between each mix tank and the pump
fluid inlet, isolate these components for servicing.
3.
Be sure the supply line (C) between the pump and
mix tanks is level.
