Grounding
Installation
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 3.
The acetal pump contains stainless steel fibers
which make the wetted parts conductive. Attaching
the ground wire to the grounding screw will ground
the air motor and the wetted parts.
The polypropylene and PVDF pumps are not
conductive. Attaching the ground wire to the
grounding screw will ground only the air motor.
When pumping conductive flammable fluids, al-
ways ground the entire fluid system by making
sure the fluid system has an electrical path to a
true earth ground (see Fig. 2). Never use a polypropylene or PVDF pump with non-conductive
flammable fluids as specified by your local fire
protection code.
Ground all of this equipment:
Pump: 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.
222011 Ground Wire and Clamp.
NOTE: When pumping conductive flammable fluids
with a polypropylene or PVDF pump, always ground
the entire fluid system. See the WARNING left. Fig. 2
shows a recommended method of grounding flammable fluid containers during filling. This is only a
guide; contact your Graco distributor for assistance in
grounding your system.
Y
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.

Installation
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.
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.
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 grounded.
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.

CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants
could affect your fluid supply. See Air Exhaust
Ventilation on page 10.
1. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, 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 the air valve cover (2), air inlet, and fluid
inlet and outlet ports are easily accessible.
4. Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
Installation of Remote Pilot Air Lines
Fluid Suction Line
If using a conductive (Acetal) pump, use conductive
hoses (G). If using a non-conductive (polypropylene or PVDF) pump, ground the fluid system. See
Grounding on page 5.
The pump fluid inlet (R) is a 1” raised face flange.
See Flange Connections on page 8.
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.
At inlet fluid pressures greater than 15 psi
(104 kPa, 1 bar), diaphragm life will be shortened.
See the Technical Data on page 32 for maximum
suction lift (wet and dry).
Fluid Outlet Line
WARNING
1. Refer to Parts Drawings. Connect air line to pump
as in preceding steps.
2. Connect 1/4 in. O.D. tubing to push type connectors (14) on air motor of pump.
NOTE: by replacing the push type connectors, other
sizes or types of fittings may be used. The new fittings
will require 1/8 in. npt threads.
3. Connect remaining ends of tubes to external air
signal, such as Graco’s Cycleflo (P/N 195264) or
Cycleflo II (P/N195265) controllers.
NOTE: the air pressure at the connectors must be at
least 30% of the air pressure to the air motor for the
pump to operate.
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.
1. Use grounded fluid hoses (L). The pump fluid
outlet (S) is a 1” raised face flange. Refer to
Flange Connections on page 8.
2. Install a fluid drain valve (J) near the fluid outlet.
See the WARNING above.
3. Install a shutoff valve (K) in the fluid outlet line.

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 FIRE OR EXPLOSION
HAZARD and TOXIC FLUID HAZARD
on page 3, before operating 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
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 (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 3/4
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.

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
Are instructed to relieve pressure
Stop pumping
Check, clean, or service any system equipment
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 5.
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 in water. If the water could
contaminate the fluid you are pumping, flush the pump
thoroughly with a compatible solvent. 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.
308443 11
Operation
Operation of Remote Piloted Pumps
1. 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).
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.
12 308443
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.
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
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Always flush the pump and follow the
Pressure Relief Procedure on page 11 before storing
it for any length of time. Use a compatible solvent.
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 30.
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.

Repair Kit Matrix
For Husky 1040 Acetal, Polypropylene, and PVDF Pumps, Series A
Repair Kits may be ordered separately. To repair the air valve, order Part No. 236273 for aluminum center housing
models and Part 255061 for stainless steel center housing models (see page 26). Parts included in the Air Valve
Repair Kit are marked with a symbol in the parts list, for example (3).
To repair your pump, select the six digits which describe your pump from the following matrix, working from left to
right. The first digit is always D, the second digit is always 0 (zero), and the third is always 7. The remaining three
digits define the materials of construction. Parts included in the kit are marked with an asterisk in the parts list, for
example (201*). For example, if your pump has polypropylene seats, PTFE balls, and PTFE diaphragms, order
Repair Kit D 0 7 9 1 1. If you only need to repair certain parts (for example, the diaphragms), use the 0 (null)
digits for the seats and balls, and order Repair Kit D 0 7 0 0 1. The digits in the matrix do not correspond to the
ref. nos. in the parts drawing and lists on pages 26 to 27.
