WARNING

Installation
312877A 7
Mounting
1. Be sure the mounting surface can support
the weight of the pump, hoses, and acces-
sories, as well as the stress caused during
operation.
2. For all mountings, be sure the pump is
bolted directly to the mounting surface.
3. For ease of operation and service, mount
the pump so air valve, air inlet, fluid inlet
and fluid outlet ports are easily accessible.
4. Rubber Foot Mounting Kit 236452 is avail-
able to reduce noise and vibration during
operation.
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical cur-
rent due to static build up or in the event of a
short circuit.
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. 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) com-
bined hose length to ensure grounding conti-
nuity.
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 ground-
ing continuity.
•The pump exhaust air may contain contam-
inants. Ventilate to a remote area. See Air
Exhaust Ventilation on page 8.
•Never move or lift a pump under pressure.
If dropped, the fluid section may rupture.
Always follow the Pressure Relief Proce-
dure on page 14 before moving or lifting
the pump.
Polypropylene: Only conductive polypropyl-
ene pumps have a ground screw. Standard
polypropylene pumps are not conductive.
Never use a non-conductive polypropylene
pump with non-conductive flammable fluids.
Follow your local fire codes. When pumping
conductive flammable fluids, always ground
the entire fluid system as described.

ti12214a
GS R

Installation
8312877A
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.
Air Line
See FIG. 3 and FIG. 4, pages 10 and 11.
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.
Reed Switch
Pulse Count models are intended for use with
customer-supplied fluid management or inven-
tory tracking systems. Attach an M12, 5-pin
female cable to connect the reed switch to your
data monitoring system. See Manual 406824.
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 dia-
phragm ruptures. If the diaphragm rup-
tures, the fluid being pumped will exhaust
with the air.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.

Installation
312877A 9
Fluid Supply Line
See FIG. 3 and FIG. 4, pages 10 and 11.
1. Use grounded fluid supply lines (G). See
Grounding, page 7.
2. If the inlet fluid pressure to the pump is
more than 25% of the outlet working pres-
sure, the ball check valves will not close
fast enough, resulting in inefficient pump
operation.
3. At inlet fluid pressures greater than 15 psi
(0.1 MPa, 1 bar), diaphragm life will be
shortened.
4. For maximum suction lift (wet and dry), see
Technical Data, page 22.
Fluid Outlet Line
See FIG. 3 and FIG. 4, pages 10 and 11.
1. Use grounded fluid hoses (L). See
Grounding, page 7.
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 pre-
vent 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 15.
Tighten Fasteners Before Setup
Before using the pump for the first time, check
and retorque all external fasteners. Follow
Torque Instructions, page 16. 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 7.
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 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.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.

Maintenance
312877A 15
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 oper-
ation instructions.
Pump Shutdown
At the end of the work shift and before you
check, adjust, clean or repair the system, fol-
low Pressure Relief Procedure, page 14.
Maintenance
Maintenance Schedule
Establish a preventive maintenance schedule,
based on the pump’s service history. Sched-
uled 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.
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 compati-
ble solvent.
Always flush the pump and relieve the pres-
sure before storing it for any length of time.

Maintenance
16 312877A
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 until each
screw is torqued to 100 in-lb (11.3 N•m).
Repeat for manifolds. See FIG. 7.
Retorque the air valve fasteners (V) in a criss-
cross pattern to specified torque.
Plastic center sections: 55 in-lb (6.2 N•m)
