Installation
General Information
• The typical installation shown in FIG. 2, page 8, is
only a guide for selecting and installing system com-
ponents. Contact your Graco distributor for assis-
tance in planning a system to suit your needs.
• Always use genuine Graco parts and accessories.
• Reference numbers and letters in parentheses refer
to the callouts in the figures.
Tighten Clamps Before First Use
After you unpack the pump, and before you use it for the
first time, check all clamps and tighten as necessary.
Grounding
•Pump: Attach a ground wire (Y) to the grounding
strip (8) with the screw (9a), lockwasher (9b), and
nut (9c), as shown in FIG. 1, and per local code.
Connect the clamp end of the ground wire to a true
earth ground. Order Part No. 238909 Ground Wire
and Clamp.
•Fluid hoses: Use only grounded hoses with a maxi-
mum of 500 ft. (150 m) combined hose length to
ensure grounding continuity.
•Air compressor: Follow the manufacturer’s recom-
mendations.
•All solvent pails used when flushing:Follow the local
code. Use only metal pails, which are conductive.
Do not place the pail on a non-conductive surface,
such as paper or cardboard, which interrupts the
grounding continuity.
•Fluid supply container: Follow the local code.
The pump is heavy and may cause injury if dropped.
Lift the pump by grasping the outlet manifold securely.
If dropped, the pump may rupture. To avoid serious
injury from splashing fluid, follow the Pressure Relief
Procedure on page 11 before moving the pump.
To reduce the risk of serious injury due to burns, insu-
late the pump before pumping hot fluids.
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.

Mounting
• Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
• For all mountings, be sure the pump is bolted
directly to the mounting surface.
• For ease of operation and service, mount the pump
so the air valve cover, air inlet, and fluid inlet and
outlet ports are easily accessible.
Air Line
1. Install the air line accessories as shown in FIG. 2.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the accesso-
ries is grounded.
a. Install an air regulator/filter assembly (C) and
gauge to control the fluid pressure. The fluid
outlet pressure will be the same as the setting of
the air regulator. The air line filter removes
harmful dirt and moisture from the compressed
air supply.
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. See the WARNING above. Locate the other
master air valve (E) upstream from all air line
accessories and use it to isolate them during
cleaning and repair.
2. Install a grounded, flexible air hose (A) between the
accessories and the 1/4 npt(f) pump air inlet. Use a
minimum 1/4 in. (6.3 mm) ID air hose. Screw an air
line quick disconnect coupler (D) onto the end of the
air hose (A), and screw the mating fitting into the
pump air inlet snugly.
Fluid Suction Line
1. Use flexible, grounded fluid hoses (F). The inlet fits
sanitary tubing of 1 to 1.5-inch OD or DIN 25.
2. For best sealing results, use a standard tri-clamp or
DIN style sanitary gasket of a flexible material such
as EPDM or Buna-N.
3. If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in ineffi-
cient pump operation. Excessive inlet fluid pressure
also will shorten diaphragm life. Approximately 3 - 5
psi (0.02 - 0.03 MPa, 0.21-0.34 bar) should be ade-
quate for most materials.
4. For maximum suction lift (wet and dry), see Techni-
cal Data, page 26. For best results, always install
the pump as close as possible to the material
source.
NOTICE
Pump exhaust air may contain contaminants that can
contaminate the fluid supply. Ventilate to a remote
area. See Air Exhaust Ventilation on page 10.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury, including
splashing in the eyes or on the skin, injury from moving
parts, or contamination from hazardous fluids. A
bleed-type master air valve (B) is required in the sys-
tem to relieve air trapped between this valve and the
pump.
See FIG. 2, page 8.
In the step below, do not connect the quick-disconnect
coupler (D) on the air hose to the mating fitting on the
pump until you are ready to operate the pump. Con-
necting the coupler too early can result in unintentional
operation of the pump, leading to serious injury from
moving parts, splashing fluid in the eyes or on the skin,
and contact with hazardous fluids.

Fluid Outlet Line 1. Use flexible grounded fluid hoses (J).
2. For best sealing results, use a standard tri-clamp or
DIN style sanitary gasket of a flexible material such
as EPDM, Buna-N.
3. Install a fluid drain valve (G) near the fluid outlet.
See the WARNING, and FIG. 2.
4. Install a shutoff valve (H) in the fluid outlet line.
FIG. 2: Typical Floor-Mount Installation
A fluid drain valve (G) is required to relieve pressure in
the hose if it is plugged. The drain valve reduces the
risk of serious injury, including splashing in the eyes or
on the skin, or contamination from hazardous fluids
when relieving pressure. Install the valve close to the
pump fluid outlet. See FIG. 2.

Changing the Orientation of the
Fluid Inlet and Outlet Ports
The pump is shipped with the ports facing the same
direction. To reverse the orientation of the ports:
1. Remove the clamps (12) holding the inlet and/or
outlet manifold to the covers.
NOTE: Inspect the o-rings and replace if necessary.
2. Reverse the manifold and reattach. Install and
tighten clamps snugly.

Air Exhaust Ventilation The air exhaust port is 3/8 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
To provide a remote exhaust:
1. Remove the muffler (P) from the pump air exhaust
port.
2. Install a grounded air exhaust hose (T) and connect
the muffler (P) to the other end of the hose. The
minimum size for the air exhaust hose is 3/8 in.
(9.5 mm) ID. If a hose longer than 15 ft (4.57 m) is
required, use a larger diameter hose. Avoid sharp
bends or kinks in the hose.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures. See
FIG. 4.
FIG. 4: Venting Exhaust Air
To avoid serious injury from explosion or hazardous
fluids:
• be sure the system is properly ventilated for your
type of installation.
• vent the exhaust away from people, animals, food
handling areas, and all sources of ignition
• place an appropriate container at the end of the air
exhaust line to catch fluid. If a diaphragm ruptures,
the fluid being pumped will exhaust with the air.
