WARNING
HAZARDOUS FLUIDS
Improper handling of hazardous fluids or inhaling toxic vapors can cause extremely serious injury or
death from splashing in the eyes, ingestion, or bodily contamination. Observe all the following
precautions when you handle hazardous or potentially hazardous fluids.
•Know what fluid you are pumping and its specific hazards. Take precautions to avoid a toxic fluid
spill.
•Always wear appropriate clothing and equipment, such as eye protection and breathing
apparatus, to protect yourself.
•Store hazardous fluid in an appropriate, approved container. Dispose of it according to all Local,
State, and Federal guidelines for hazardous fluids.
•Secure the fluid outlet hose tightly into the receiving container to prevent it from coming loose and
improperly draining the fluid.
•Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas.
If the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on
page 5.
FIRE AND EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose. If the equipment is not
properly grounded, sparking may occur. Sparks can ignite fumes from solvents and the fluid being
pumped, dust particles, and other flammable substances, whether you are pumping indoors or
outdoors, and can cause a fire or explosion and serious injury and property damage.
•To reduce the risk of static sparking, ground the pump and all other equipment used or located in
the work area. Check your local electrical code for detailed grounding instructions for your area
and type of equipment. See Grounding on page 4.
•If you experience any static sparking or even a slight shock while using this equipment, stop
pumping immediately. Check the entire system for proper grounding. Do not use the system
again until you have identified and corrected the problem.
•Pipe and dispose of the exhaust air safely, away from all sources of ignition. If the diaphragm fails,
the fluid is exhausted along with the air. See Air Exhaust Ventilation on page 5.
•Do not smoke in the work area. Do not operate the equipment near a source of ignition or an open
flame, such as a pilot light.

Installation
Tightening Threaded Fasteners Before First
Use
Before using the pump for the first time, check and
retorque all external fasteners. See Torque Sequence,
page 18. After the first day of operation, retorque the
fasteners. Although pump use varies, a general guideline
is to retorque fasteners every two months.
Use a compatible thread sealant on all male threads.
Tighten all connections firmly to avoid air or fluid leaks.
Grounding
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment.
Acetal Pump Grounding Instructions
For polypropylene and PVDF pumps, see the warning
above.
Ground all of this equipment.
Pump: Connect a ground wire (A) and clamp, Part No.
222011. See FIG. 1. The pump grounding locations are
on the manifold between the inlet and outlet ports. Use
the nut (B) and bolt (C) that are provided with the pump,
and install as follows:
1. Place the nut in the nut catcher on the underside of
the manifold.
2. Insert the bolt through the loop end of the ground
wire.
3. Insert the bolt through the hole on the pump manifold
and tighten it into the nut that you positioned in
step 1.
4. Connect the clamp end of the ground wire to a true
earth ground.
•Air and fluid hoses: Use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity.
•Air compressor: Follow the manufacturer’s
recommendations.
•All solvent pails used when flushing: Follow the local
code. Use only grounded 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.
CAUTION
To avoid pump damage, do not overtighten the
fittings to the pump.
WARNING
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
you operate the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
The acetal pump contains stainless steel fibers which
make the wetted parts conductive. Attaching the
ground wire to one of the grounding locations
grounds the wetted parts.
The polypropylene and PVDF pumps are not
conductive. When you pump conductive flammable
fluids, always ground the entire fluid system by
making sure the fluid has an electrical path to a true
earth ground. See FIG. 1. Never use a polypropylene
or PVDF pump with non-conductive flammable fluids
as specified by your local fire protection code.
Consult your fluid supplier to determine the
conductivity or resistivity of your fluid.
US Code (NFPA 77 Static Electricity) recommends a
conductivity greater than 50 x 10-12 Siemans/meter
(mhos/meter) over your operating temperature range
to reduce the hazard of fire. Consult your fluid
supplier to determine the conductivity or resistivity of
your fluid. The resistivity must be less than 2 x 1012
ohm-centimeters.

•Mounting Bracket:
The pump is shipped with a 90 degree mounting
bracket (60). Mount the pump to the bracket using
the four screws (61) provided. Secure the opposite
portion of the mounting bracket to a horizontal
surface. The mounting bracket must be used for
proper pump performance.
•Be sure the mounting 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 secured with
screws and nuts.
•Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps. To
prevent potential injury or equipment damage, do not
expose pump or the plastic components to direct
sunlight for prolonged periods.
WARNING
TOXIC FLUID HAZARD
Read the HAZARDOUS FLUIDS and
FIRE AND EXPLOSION HAZARD
sections on page 3 before you operate
this pump.
Be sure the systemis properly ventilated
for your type of installation. You must
vent the exhaust to a safe place, away
from people, animals or food handling
areas when pumping flammable or
hazardous fluids.
If the diaphragm ruptures, the fluid being pumped is
exhausted with the air. Place a container at the end of
the air exhaust line to catch fluid in case the
diaphragm ruptures, and disconnect the pump.
CAUTION
The pump exhaust air may contain contaminants. If
needed, ventilate to a remote area to reduce possible
fluid contamination. See Air Exhaust Ventilation on
page 5.
FIG. 2
WARNING
To reduce the risk of serious injury, splashing in the
eyes or on the skin, and toxic fluid spills, never move
or lift a pump under pressure. If dropped, the fluid

Installation
Air Lines
1. Mount the air line accessories on the wall or on a
bracket. Be sure the air line supplying the
accessories is grounded.
a. The pump speed can be controlled in one of two
ways: To control it on the air side, install an air
regulator. To control it on the fluid side, install a
fluid valve near the outlet.
b. Install a bleed-type master air valve downstream
from the air regulator, and use it to relieve
trapped air. See the Bleed-Type Master Air
Valve and Fluid Drain Valve warning above.
Locate another bleed-type master air valve
upstream from all air line accessories, and use it
to isolate the accessories during cleaning and
repair.
c. The air line filter removes harmful dirt and
moisture from the compressed air supply.
2. Install a flexible air hose between the accessories
and the pump air inlet. Screw the air line fitting into
the air inlet.
3. Do not restrict the exhaust port. Excessive exhaust
restriction can cause erratic pump operation.
Fluid Lines
FIG. 3. On each end of the fluid manifold are a fluid IN
port and a fluid OUT port. NOTE: Make sure the fluid
OUT port on the fluid manifold is mounted up. This
will assure proper pump priming. Fluid-in and fluid-out
lines can be connected on the same end, or opposite
ends of the manifold. Plug ports that are not used (plugs
provided).
Typical Installation
The installations shown in FIG. 4 are only a guide to help
select and install a pump; they are not actual system
designs.
Typical installation includes (not supplied by Graco):
•For solenoid operation: a four-way, 5-port, 3-position
solenoid valve with 1/4-in. ports, or two 3-position
3-way valves. Mac series 44 (4-way), or series 35
(3-way). Either way, air pressure should be released
if not cycling.
•PLC or timer. Consult your local industrial controls
distributor.
WARNING
Bleed-Type Master Air Valve and Fluid Drain
Valve
A bleed-type master air valve and a fluid drain valve
are required on your system.
The bleed-type master air valve relieves air trapped
between itself and the pump. Trapped air can cause
the pump to cycle unexpectedly, which could result in
serious bodily injury, including splashing in the eyes,
injury from moving parts, or contamination from
hazardous fluids.
The fluid drain valvereduces the risk of serious bodily
injury, including splashing in the eyes or on the skin,
or contamination from hazardous fluids. Install the
fluid drain valve close to the pump’s fluid outlet to
relieve pressure in the hose if the hose becomes
plugged.
FIG. 3
CAUTION
For solenoid operation, the pump must exhaust
through the solenoid. Failure to exhaust through
solenoid could cause the diaphragms to fail.

Operation
Pressure Relief Procedure
1. Shut off air and reserve air to the pump.
2. Open the dispensing valve if the system has one.
3. Open the fluid drain valve to relieve all system
pressure, and have a container ready to catch the
drainage.
Flushing the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush it thoroughly
with a compatible solvent. Follow the procedure in
Starting and Adjusting the Pump.
Starting and Adjusting the Pump
1. Be sure the pump is properly grounded. Read and
follow the instructions in Grounding on page 4.
2. Check all fittings to be sure they are tight. Be sure to
use a compatible liquid thread sealant on all male
threads. Tighten the fluid inlet and outlet fittings and
plugs securely. Retorque all fasteners before
start-up. See Torque Sequence, page 18.
3. Place the suction tube (if used) in the fluid to be
pumped.
4. Place the end of the outlet hose into an appropriate
container.
5. Close the fluid drain valve.
6. With the air regulator closed, open all bleed-type
master air valves.
7. If the outlet hose has a dispensing device, hold it
open while continuing with step 8.
8. Slowly open the air regulator until the pump starts to
cycle. Allow the pump to cycle until all air is pushed
out of the lines and the pump is primed.
NOTE: To prime a remote solenoid-operated air
valve, operate the pump at a minimum 60 cpm rate
until the pump is fully primed.
Pump Shutdown
At the end of the work shift,and before you check, adjust,
clean, or repair the system, relieve air and fluid
pressure.
WARNING
To reduce the risk of serious injury, including
splashing fluid in the eyes or on the skin, follow this
procedure whenever you are instructed to relieve
pressure, when you shut off the pump, and before
you check, adjust, clean, move, or repair any system
equipment.
WARNING
To reduce the risk of serious injury, splashing in the
eyes or on the skin, and toxic fluid spills, never move
or lift a pump under pressure. If the pump is dropped,
the fluid section could rupture. Always follow the
Pressure Relief Procedure above before you move

Maintenance
Lubrication
The air valve is lubricated at the factory and designed to
operate without additional lubrication.
If added lubrication is desired, every 500 hours of
operation (or monthly), remove the hose from the pump
air inlet and add two drops of machine oil to the air inlet.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage,
and replace as necessary. Be sure all threaded
connections are tight and free of leaks.
Check fasteners. Tighten or retorque as necessary.
Although pump use varies, a general guideline is to
retorque fasteners every two months. See Torque
Sequence, page 18.
Flushing and Storage
Flush the pump to prevent the fluid from drying or
freezing in the pump and damaging it. Always flush the
pump and relieve the pressure before storing for any
length of time. Use a compatible solvent.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses, close the air
regulator, and remove the suction hose from the solvent
and place it in the fluid to be pumped.
If you are shutting down the pump, remove the suction
hose from the fluid container, run the pump until the fluid
is forced out of the system, and shut off the air supply
immediately.
CAUTION
Do not over-lubricate the pump. Excess oil is
exhausted through the muffler, which could
contaminate your fluid supply or other equipment.
WARNING
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
