Installation
The Typical Installation shown in FIG. 4 is only a guide
for selecting and installing system components. Contact
your Graco distributor for assistance in planning a
system to suit your needs.
Tighten Fasteners Before Setup
Before using the pump for the first time, check and
retorque all external fasteners. Follow Torque
Instructions, page 18.
Tips to Reduce Cavitation
Cavitation in a diaphragm pump is the formation and
collapse of bubbles in the pumped liquid. Frequent or
excessive cavitation can cause serious damage,
including pitting and early wear of fluid chambers, balls,
and seats. It may result in reduced efficiency of the
pump. Cavitation damage and reduced efficiency both
result in increased operating costs.
Cavitation depends on the vapor pressure of the
pumped liquid, the system suction pressure, and the
velocity pressure. It can be reduced by changing any of
these factors.
1. Reduce vapor pressure: Decrease the temperature
of the pumped liquid.
2. Increase suction pressure:
a. Lower the installed position of the pump relative
to the liquid level in the supply.
b. Reduce the friction length of the suction piping.
Remember that fittings add friction length to the
piping. Reduce the number of fittings to reduce
the friction length.
c. Increase the size of the suction piping.
NOTE: Be sure the inlet fluid pressure does not exceed
25% of the outlet working pressure.
3. Reduce liquid velocity: Slow the cyclic rate of the
pump.
Pumped liquid viscosity is also very important but
normally is controlled by factors that are process
dependent and cannot be changed to reduce cavitation.
Viscous liquids are more difficult to pump and more
prone to cavitation.
Graco recommends taking all of the above factors into
account in system design. To maintain pump efficiency,
supply only enough power to the pump to achieve the
required flow.
Graco distributors can supply site specific suggestions
to improve pump performance and reduce operating
costs.

Installation
312877ZAD 9
Mounting
1. For wall mounting, order Graco Kit 24C637.
2. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
3. For all mountings, be sure the pump is bolted
directly to the mounting surface.
4. For ease of operation and service, mount the pump
so air valve, air inlet, fluid inlet and fluid outlet ports
are easily accessible.
5. Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
6. 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.
Grounding
Pump: See FIG. 1. Loosen the grounding screw (GS).
Insert one end of a 12 ga. minimum ground wire (R)
behind the grounding screw and tighten the screw
securely. Do not exceed 15 in-lb (1.7 N•m). Connect the
clamp end of the ground wire to a true earth ground. A
ground wire and clamp, Part 238909, is available from
Graco.
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 manufacturer’s
recommendations.
Fluid supply container: Follow local code.
Solvent pails used when flushing: Follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
Check your system electrical continuity after the initial
installation, and then set up a regular schedule for
checking continuity to be sure proper grounding is
maintained.
• The pump exhaust air may contain contaminants.
Ventilate to a remote area. See Air Exhaust
Ventilation on page 11.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure on page 16
before moving or lifting the pump.
The equipment must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
Polypropylene and PVDF: Only aluminum,
conductive polypropylene, hastelloy, and stainless
steel pumps have a ground screw. Standard
polypropylene and PVDF pumps are not conductive.
Never use a non-conductive polypropylene or PVDF
pump with non-conductive flammable fluids. Follow
your local fire codes. When pumping conductive
flammable fluids, always ground the entire fluid
system as described.

Air Line
See FIG. 4, page 13.
1. Install an air regulator (C) and gauge to control the
fluid pressure. The fluid stall pressure will be the
same as the setting of the air regulator.
2. Locate a bleed-type master air valve (B) close to the
pump and use it to relieve trapped air. Be sure the
valve is easily accessible from the pump and
located downstream from the regulator.
3. Locate another master air valve (E) upstream from
all air line accessories and use it to isolate them
during cleaning and repair.
4. An air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
5. Install a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (D).
Use a minimum 3/8 in. (10 mm) ID air hose.
Installation of Remote Pilot Air Lines
1. Connect an air supply line to the pump (A, FIG. 3,
page 11).
2. Insert 5/32 OD tubing into the push-to-connect
fitting on each pilot valve (113).
3. Connect remaining ends of tubes to external air
signal, such as Graco’s CycleFlo™(PN 195264) or
CycleFlo II (PN 195265) controllers.
Reed Switch
Pulse Count models are intended for use with
customer-supplied fluid management or inventory
tracking systems. Attach an M12, 5-pin female cable to
connect the reed switch to your data monitoring system.
See Manual 406824.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
splashing.
NOTICE
Pilot supply pressure should not exceed 25-50% of
main air supply pressure. If pilot supply pressure is
too high, the pump could leak air or exhaust
excessive air at stall.

Air Exhaust Ventilation
The air exhaust port is 3/4 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 (T) from the pump air exhaust
port.
2. Install a grounded air exhaust hose (U) and connect
the muffler (T) to the other end of the hose. The
minimum size for the air exhaust hose is 3/4 in. (19
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 at the end of the air exhaust line
to catch fluid in case a diaphragm ruptures. If the
diaphragm ruptures, the fluid being pumped will
exhaust with the air.

Fluid Supply Line
See FIG. 4, page 13.
1. Use grounded, flexible fluid supply lines (G). See
Grounding, page 9.
2. If the inlet fluid pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in
inefficient 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 adequate for most materials.
3. For maximum suction lift (wet and dry), see
Technical Specifications, page 25. For best
results, always install the pump as close as possible
to the material source.
Fluid Outlet Line
See FIG. 4, page13.
1. Use grounded, flexible fluid hoses (L). See
Grounding, page 9.
2. Install a fluid drain valve (J) near the fluid outlet.
3. Install a shutoff valve (K) in the fluid outlet line.

Fluid Pressure Relief Valve
FIG. 6. Fluid pressure relief kit (Aluminum pumps only, 1050A models)
Some systems may require installation of a pressure
relief valve at the pump outlet to prevent
overpressurization and rupture of the pump or hose.
Thermal expansion of fluid in the outlet line can cause
overpressurization. Thermal expansion can occur when
using long fluid lines exposed to sunlight or ambient
heat, or when pumping from a cool to a warm area (for
example, from an underground tank).
Overpressurization also can occur if the Husky pump is
used to feed fluid to a piston pump, and the intake valve
of the piston pump does not close, causing fluid to back
up in the outlet line.
FIG. 6 shows Fluid Pressure Relief Kit 238428 for
aluminum pumps. Use Fluid Pressure Relief Kit
112119, not shown, for plastic pumps.

Operation
Pressure Relief Procedure
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve fluid pressure.
Have a container ready to catch the drainage.
Flush the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the pump
thoroughly with a compatible solvent. See Flushing and
Storage, page 17.
Tighten Fasteners Before Setup
Before using the pump for the first time, check and
retorque all external fasteners. Follow Torque
Instructions, page 18. After the first day of operation,
retorque the fasteners.
Starting and Adjusting the Pump
1. Be sure the pump is properly grounded. Refer to
Grounding on page 9.
2. Check fittings to be sure they are tight. Use a
compatible liquid thread sealant on male threads.
Tighten fluid inlet and outlet fittings securely.
3. Place the suction tube (if used) in fluid to be
pumped.
NOTE: If fluid inlet pressure to the pump is more than
25% of outlet working pressure, the ball check valves
will not close fast enough, resulting in inefficient pump
operation.
4. Place the end of the fluid hose into an appropriate
container.
5. Close the fluid drain valve.
6. Back out the air regulator knob, and open all
bleed-type master air valves.
7. If the fluid hose has a dispensing device, hold it
open.
8. Pumps with runaway protection: Enable the
prime/flush function by pushing the prime/flush
button on the DataTrak.
9. Slowly increase air pressure with the air regulator
just until the pump starts to cycle. Allow the pump to
cycle slowly until all air is pushed out of the lines
and the pump is primed.
NOTE: Use lowest possible air pressure to prime, just
enough to cycle the pump. If the pump does not prime
as expected, turn air pressure DOWN.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
splashing.
NOTICE
When replacing Husky 1040s: The Husky 1050
operates more efficiently than did the 1040. Reduce air
inlet pressure by approximately 20 percent to maintain
an equivalent fluid output.

Maintenance

10. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
11. Close the dispensing valve, if used.
12. Close the bleed-type master air valve.
13. Pumps with runaway protection: Disable the
prime/flush function by pushing the prime/flush
button on the DataTrak.
DataTrak Operation
See DataTrak manual 313840 for all DataTrak
information and parts, including detailed operation
instructions.
Pump Shutdown
At the end of the work shift and before you check,
adjust, clean or repair the system, follow Pressure
Relief Procedure, page 16.
Maintenance
Maintenance Schedule
Establish a preventive maintenance schedule, based on
the pump’s service history. Scheduled maintenance is
especially important to prevent spills or leakage due to
diaphragm failure.
Lubrication
The pump is lubricated at the factory. It is designed to
require no further lubrication for the life of the pump.
There is no need to add an inline lubricator under
normal operating conditions.
Tighten Threaded Connections
Before each use, check all hoses for wear or damage
and replace as necessary. Check to be sure all threaded
connections are tight and leak-free. Check fasteners.
Tighten or retorque as necessary. Although pump use
varies, a general guideline is to retorque fasteners every
two months. See Torque Instructions, page 18.
Flushing and Storage
• Flush before fluid can dry in the equipment, at the
end of the day, before storing, and before repairing
equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Use a compatible solvent.
Always flush the pump and relieve the pressure before
storing it for any length of time.

Maintenance

Torque Instructions
NOTE: Fluid cover and manifold fasteners have a
thread-locking adhesive patch applied to the threads. If
this patch is excessively worn, the fasteners may loosen
during operation. Replace screws with new ones or
apply medium-strength (blue) Loctite or equivalent to
the threads.
If fluid cover or manifold fasteners have been loosened,
it is important to torque them using the following
procedure to improve sealing.
NOTE: Always completely torque fluid covers before
torquing manifolds.
Start all fluid cover screws a few turns. Then turn down
each screw just until head contacts cover. Then turn
each screw by 1/2 turn or less working in a crisscross
pattern to specified torque. Repeat for manifolds.
Fluid cover and manifold fasteners:
90 in-lb (10.2 N•m)
Retorque the air valve fasteners (V) in a crisscross
pattern to specified torque.
Plastic center sections: 55 in-lb (6.2 N•m)
Metal center sections: 80 in-lb (9.0 N•m)
