Grounding
WARNING
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
operating the pump, ground the system
as explained below. Also, read the section FIRE AND EXPLOSION HAZARD,
on page 4.
Polypropylene and PVDF are not conductive.
Attaching the ground wire to the grounding lug will
ground only the air motor. When pumping 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 a PVDF pump with
non-conductive flammable fluids as specified by
your local fire protection code.
Ground all of this equipment:
D Air Motor: Connect a ground wire and clamp as
shown in Fig. 1. Loosen the grounding screw (W).
Insert one end of a 12 ga (1.5 mm@) minimum
ground wire (Y) behind the grounding screw and
tighten the screw securely. Connect the clamp end
of the ground wire to a true earth ground. Order
Part No. 237569 Ground Wire and Clamp.
NOTE: When pumping conductive flammable fluids
with a polypropylene or a PVDF pump, always ground
the entire fluid system. See the WARNING on page
6.
D Air and fluid hoses: Use only electrically conductive
hoses.
D Air compressor: Follow the manufacturer’s recom-
mendations.
D 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.
US Code (NFPA 77 Static Electricity) recommends
a conductivity greater than 50 x 10
ter (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.
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.

Air Line
WARNING
A bleed-type master air valve (B) is required in
your system to relieve air trapped between this
valve and the pump. Trapped air can cause the
pump to cycle unexpectedly, which could result in
serious injury, including splashing in the eyes or on
the skin, injury from moving parts, or contamination
from hazardous fluids. See Fig. 2.
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 accessories is electrically conductive.
a. Install an air regulator (C) and gauge to control
the fluid pressure. The fluid outlet pressure will
be the same as the setting of the air regulator.
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. See the WARNING at left. Locate the other
master air valve (E) upstream from all air line
accessories and use it to isolate them during
cleaning and repair.
c. The air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
2. Install an electrically conductive, flexible air hose
(A) between the accessories and the 1/2 npt(f)
pump air inlet (N). See Fig. 2. Use a minimum 1/2”
(13 mm) ID air hose.
3. Screw an air line quick disconnect coupler (D) onto
the end of the air hose (A); be sure the coupler
porting is large enough to not restrict the air flow,
which will affect pump performance. Screw the
mating fitting into the pump air inlet snugly. Do not
connect the coupler (D) to the fitting until you are
ready to operate the pump.

could affect your fluid supply. See Air Exhaust
Ventilation on page 11.
D Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
Fluid Suction Line
1. The pump fluid inlet (R) is a 2” raised face flange.
Refer to Flange Connections on page 9.
2. 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
inefficient pump operation.
3. At inlet fluid pressures greater than 15 psi
(0.1 MPa, 1 bar), diaphragm life will be shortened.
4. See the Technical Data on page 34 for maximum
suction lift (wet and dry).
Fluid Outlet Line
WARNING
A fluid drain valve (J) 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.
D For all mountings, be sure the pump is bolted
directly to the mounting surface.
D For ease of operation and service, mount the pump
so the air valve cover (2), air inlet, and fluid inlet
and outlet ports are easily accessible.
D Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
1. The pump fluid outlet (S) is a 2” raised face flange.

Fluid Pressure Relief Valve
CAUTION
Some systems may require installation of a pressure relief valve at the pump outlet to prevent
overpressurization and rupture of the pump or
hose. See Fig. 5.
Thermal expansion of fluid in the outlet line can
cause overpressurization. This 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 can also occur if the Husky
pump is being 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.

Air Exhaust Ventilation
WARNING
FIRE AND EXPLOSION HAZARD
Be sure to read and follow the warnings
and precautions regarding TOXIC
FLUID HAZARD, and FIRE OR EXPLOSION HAZARD on page 4, before op-
erating this pump.
Be sure the system is properly ventilated for your
type of installation. You must vent the exhaust to a
safe place, away from people, animals, food handling areas, and all sources of ignition when pumping
flammable or hazardous fluids.
Diaphragm failure will cause the fluid being
pumped to exhaust with the air. Place an appropriate container at the end of the air exhaust line to
catch the fluid. See Fig. 6.
VENTING EXHAUST AIR
FBEC
The air exhaust port is 3/4 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
If the muffler (P) is installed directly to the air exhaust
port, apply PTFE thread tape or anti–seize thread
lubricant to the muffler threads before assembly.
To provide a remote exhaust:
1. Remove the muffler (P) from the pump air exhaust
port.
2. Install an electrically conductive 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 3/4 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. See Fig. 6.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious
injury from pressurized fluid, accidental spray from
the gun or splashing fluid, follow this procedure
whenever you:
D Are instructed to relieve pressure,
D Stop pumping,
D Check, clean or service any system equipment,
D Install or clean fluid nozzles.
1. Shut off the air to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve all fluid pressure, having a container ready to catch the drainage.
Flush the Pump Before First Use
1. Be sure the pump is properly grounded. Refer to
Grounding on page 6.
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 securely.
3. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: 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 inefficient
pump operation.
4. Place the end of the fluid hose (L) into an appropriate container.
5. Close the fluid drain valve (J). See Fig. 2.
The pump was tested with lightweight oil, which is left
in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the pump with a compatible solvent before using the equipment. Follow the
steps under Starting and Adjusting the Pump.
Starting and Adjusting the Pump
WARNING
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can
cause serious injury or death if splashed
in the eyes or on the skin, inhaled, or
swallowed. Do not lift a pump under pressure. If
dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure above before
lifting the pump.
6. With the pump air regulator (C) closed, open all
bleed-type master air valves (B, E).
7. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
8. Slowly open the air regulator (C) 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.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the
air regulator. Remove the suction tube from the
solvent and place it in the fluid to be pumped.
12 308550
Operation
Operation of Remote Piloted Pumps
1. Fig. 2 and Parts Drawings. Follow preceding steps
1 through 7 of Starting and Adjusting Pump.
2. Open air regulator (C).
WARNING
The pump may cycle once before the external signal is applied. Injury is possible. If pump cycles,
wait until end before proceeding.
3. Pump will operate when air pressure is alternately
applied and relieved to push type connectors (14).
Maintenance
Lubrication
The air valve is designed to operate unlubricated.
However, if 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.
NOTE: Leaving air pressure applied to the air motor for
extended periods when the pump is not running may
shorten the diaphragm life. Using a 3–way solenoid
valve to automatically relieve the pressure on the air
motor when the metering cycle is complete prevents
this from occurring.
Pump Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
At the end of the work shift, relieve the pressure.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Flush with a fluid that is compatible with
the fluid you are pumping and with the wetted parts in
your system. Check with your fluid manufacturer or
supplier for recommended flushing fluids and flushing
frequency.
CAUTION
Do not over-lubricate the pump. Oil is exhausted
through the muffler, which could contaminate your
fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.
Flushing and Storage
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 12.
Always flush the pump and relieve the pressure before
storing it for any length of time.
Tightening 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 Sequence,
page 31.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based
on the pump’s service history. This is especially important for prevention of spills or leakage due to diaphragm failure.

Reassembly – Overmolded Diaphragms
WARNING
To reduce the risk of serious injury, including
amputation, do not put your fingers or hand between the air cover and the diaphragm.
1. Lubricate and install the shaft u–cup packings
(402*) so the lips face out of the housing (1). See
Fig. 13.
2. Assemble the air side plate (104) onto the diaphragm (403). The wide, radiused side of the plate
must face the diaphragm. Apply medium–strength
(blue) Loctite or equivalent to the threads of the
diaphragm assembly. Screw the assembly into the
shaft (24) hand–tight.
5. Assemble the other diaphragm assembly to the
shaft as explained in step 2. This diaphragm will
be lifted off the air cover at this point.
6. Supply the pump with low pressure air (less than 7
psi [0.05 MPa, 0.5 bar]). The diaphragm will very
slowly pull onto the air cover. Find the pressure
that keeps the diaphragm close enough to secure
with the screws, but does not let it contact the pilot
pin.
NOTE: Do not deform the diaphragm manually. The
diaphragm needs uniform pressure to deform properly
for maximum life.
7. Align the fluid cover (101) and the center housing
(1) so the arrow (A) faces the same direction as
the air valve. Secure the cover with two of the
longer screws (108), handtight.
3. Grease the length and ends of the diaphragm shaft
(24). Insert the shaft/diaphragm assembly into one
side of the pump. Align the fluid cover (101) and
the center housing (1) so the arrow (A) faces the
same direction as the air valve. Secure the cover
with the screws (107 and 108), handtight.
4. Torque the longer screws (108) oppositely and
evenly to 190–220 in–lb (21–25 NSm), using a
13mm socket wrench. Then torque the shorter
screws (107). See Torque Sequence, page 31.
NOTE: If the diaphragm contacts the pilot pin and is
forced away from the air cover, try Step 5 again. If
necessary, return to Step 3.
8. Torque the longer screws (108) oppositely and
evenly to 190–220 in–lb (21–25 NSm), using a
13mm socket wrench. Then torque the shorter
screws (107). See Torque Sequence, page 31.
9. Reassemble the ball check valves and manifolds
as explained on page 18.
