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.  
D Know the specific hazards of the fluid you are using.  
D Do not lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the  
Pressure Relief Procedure on page 10 before lifting the pump.  
D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,  
state and national guidelines.  
D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and  
solvent manufacturer.  
D 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. Read Air Exhaust Ventilation on  
page 6.  
D Never use an acetal pump to pump acids. Take precautions to avoid acid or acid fumes from  
contacting the pump housing exterior. Stainless steel parts will be damaged by exposure to acid  
spills and fumes.  
FIRE AND EXPLOSION HAZARD  
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and  
result in a fire or explosion and serious injury.  
D Ground the equipment. Refer to Grounding on page 8.  
D If there is any static sparking or you feel an electric shock while using this equipment, stop pump-  
ing immediately. Do not use the equipment until you identify and correct the problem.  
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid  
being pumped.  
D 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. Read Air Exhaust Ventilation on page 6.  
D Keep the work area free of debris, including solvent, rags, and gasoline.  
D Electrically disconnect all equipment in the work area.  
D Extinguish all open flames or pilot lights in the work area.  
D Do not smoke in the work area.

Installation  
General Information  
CAUTION  
D The Typical Installations in Fig. 2 are only guides  
for selecting and installing system components.  
Contact your Graco distributor for assistance in  
planning a system to suit your needs.  
Safe Operating Temperatures  
Minimum: 40_ F (4_ C)  
Maximum: 225_ F (107_ C)  
These temperatures are based upon mechanical stress  
only and may be significantly altered by pumping certain  
chemicals. Consult engineering guides for chemical com-  
patibilities and temperature limits, or contact your Graco  
distributor.  
D Always use Genuine Graco Parts and Accessories.  
D Use a compatible, liquid thread sealant on all male  
threads. Tighten all connections firmly to avoid air  
or fluid leaks.  
Mountings  
Tightening Threaded Fasteners Before  
First Use  
D These pumps can be used in a variety of installa-  
tions. Be sure the mounting surface can support  
the weight of the pump, hoses, and accessories, as  
well as the stress caused during operation.  
Before using the pump for the first time, check and  
retorque all external fasteners. See Torque Se-  
quence, page 20. After the first day of operation,  
retorque the fasteners. Although pump use varies, a  
general guideline is to retorque fasteners every two  
months.  
D Fig. 2 shows some installation examples. On all  
installations, mount the pump using screws and  
nuts.  
Toxic Fluid Hazard  
Read Toxic Fluid Hazard  
on page 3.  
Pumping High-Density Fluids  
Use fluids and solvents that are compatible with the  
equipment wetted parts. Refer to the Technical Data  
section of all equipment manuals. Read the fluid and  
solvent manufacturer’s warnings.  
High density fluids may prevent the lighter non-metallic  
check valve balls from seating properly, which reduces  
pump performance significantly. Stainless steel balls  
should be used for such applications.

Installation  
2. Install an electrically conductive, flexible air hose  
Air Line  
(C) between the accessories and the 1/4 npt(f)  
pump air inlet. Use a minimum 1/4 in. (6.3 mm) ID  
air hose. Screw an air line quick disconnect cou-  
pler (D) onto the end of the air hose (C), and  
screw the mating fitting into the pump air inlet  
snugly. Do not connect the coupler (D) to the fitting  
yet.  
WARNING  
A bleed-type master air valve (B) is required in your  
system to relieve air trapped between this valve  
and the pump. See Fig. 2. 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 contamina-  
tion from hazardous fluids.  
Fluid Suction Line  
D If using a conductive (acetal) pump, use conductive  
hoses. If using a non-conductive pump, ground the  
fluid system. Read Grounding on page 8. The  
fluid inlet port is 3/4 in.  
CAUTION  
The pump exhaust air may contain contaminants.  
Ventilate to a remote area if the contaminants could  
affect your fluid supply. Read Air Exhaust Ventila-  
tion on page 6.  
D At inlet fluid pressures greater than 15 psi  
(0.1 MPa, 1 bar), diaphragm life will be shortened.  
Fluid Outlet Line  
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 acces-  
sories is electrically conductive.  
WARNING  
A fluid drain valve (H) is required in your system to  
relieve pressure in the hose if it is plugged. See  
Fig. 2. 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.  
a. The fluid pressure can be controlled in either  
of two ways. To control it on the air side, install  
an air regulator (G). To control it on the fluid  
side, install a fluid regulator (J) near the pump  
fluid outlet (see Fig. 2).  
1. Use electrically conductive fluid hoses (K). The  
pump fluid outlet is 3/4 in. Screw the fluid fitting  
into the pump outlet snugly. Do not overtighten.  
b. Locate one bleed-type master air valve (B)  
close to the pump and use it to relieve trapped  
air. Read the WARNING above. Locate the  
other master air valve (E) upstream from all air  
line accessories and use it to isolate them  
during cleaning and repair.  
2. Install a fluid regulator (J) at the pump fluid outlet  
to control fluid pressure, if desired (see Fig. 2).  
See Air Line, step 1a, for another method of  
controlling pressure.  
c. The air line filter (F) removes harmful dirt and  
moisture from the compressed air supply.  
3. Install a fluid drain valve (H) near the fluid outlet.  
Read the WARNING above.

Installation  
Fluid Pressure Relief Valve  
Air Exhaust Ventilation  
CAUTION  
Some systems may require installation of a pressure  
relief valve at the pump outlet to prevent overpres-  
surization and rupture of the pump or hose.  
See Fig. 1.  
Read Toxic Fluid Hazard on  
page 3.  
Read Fire and Explosion  
Hazard on page 3.  
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).  
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 handl-  
ing areas, and all sources of ignition when pumping  
flammable or hazardous fluids.  
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.  
Diaphragm failure will cause the fluid being pumped  
to exhaust with the air. Place an appropriate con-  
tainer at the end of the air exhaust line to catch the  
fluid. See Fig. 2 .

2
Install valve between fluid inlet and outlet ports.  
Connect fluid inlet line here.  
3
Connect fluid outlet line here.  
The air exhaust port is 3/8 npt(f). Do not restrict the air  
exhaust port. Excessive exhaust restriction can cause  
erratic pump operation.

See Venting Exhaust Air in Fig. 2. Exhaust to a  
remote location as follows:  
1. Remove the muffler (W) from the pump air exhaust  
port.  
1
2. Install an electrically conductive air exhaust hose  
(X) and connect the muffler to the other end of the  
hose. The minimum size for the air exhaust hose  
is 3/8 in. (10 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.

Grounding  
Ground all of this equipment:  
WARNING  
D Pump: The metal pump has a grounding strip in  
front of the center housing. Connect the non-clamp  
end of the ground wire to the grounding strip and  
connect the clamp end of the ground wire to a true  
earth ground. To order a ground wire and clamp,  
order Part No. 222011.  
FIRE AND EXPLOSION HAZARD  
This pump must be grounded. Before  
operating the pump, ground the system  
as explained below. Also read the sec-  
tion Fire and Explosion Hazard on  
page 3.  
D Air and fluid hoses: Use only electrically conductive  
hoses.  
The metal Husky 716 pumps have a grounding  
strip connecting the vee clamps (109). Attach a  
ground wire to the grounding strip with the screw,  
lockwasher, and nut as shown in the Grounding  
Detail on page 18.  
D Air compressor: Follow the manufacturer’s recom-  
mendations.  
D 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-conduc-  
tive surface, such as paper or cardboard, which  
interrupts the grounding continuity.  
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. 3).  
D Fluid supply container: Follow the local code.  
US Code (NFPA 77 Static Electricity) recommends  
a conductivity greater than 50 x 10-- 1 2 Siemans/me-  
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.

than 25% of the outlet working pressure, the ball check  
valves will not close fast enough, resulting in inefficient  
pump operation.  
WARNING  
PRESSURIZED EQUIPMENT HAZARD  
6. Place the end of the fluid hose (K) into an appro-  
priate container.  
The equipment stays pressurized until pressure is  
manually relieved. To reduce the risk of serious  
injury from pressurized fluid, accidental spray, or  
splashing fluid, follow this procedure whenever you  
7. Close the fluid drain valve (H).  
D Are instructed to relieve pressure  
D Stop pumping  
8. With the pump air regulator (G) closed, open all  
bleed-type master air valves (B, E).  
D Check, clean, or service any system equipment  
D Install or clean fluid nozzles  
9. If the fluid hose has a dispensing device, hold it  
open while continuing with the following step.  
Slowly open the air regulator (G) 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.  
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 pres-  
sure, and have a container ready to catch the  
drainage.  
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.  
Flush Pump Before First Use  
Operation of Remote Piloted Pumps  
The pump was tested with water. If water could contai-  
minate the fluid you are pumping, flush the pump  
thoroughly with a compatible solvent before using the  
equipment. Follow the steps under Starting and  
Adjusting Pump.  
1. Fig. 2 and Parts Drawings. Follow preceding steps  
1 through 8 of Starting and Adjusting Pump.  
2. Open air regulator (G).  
Starting and Adjusting Pump  
WARNING  
The pump may cycle once before the external sig-  
nal is applied. Injury is possible. If pump cycles,  
wait until end before proceeding.  
Read Toxic Fluid Hazard  
on page 3.  
1.  
If lifting the pump, follow the Pres-  
sure Relief Procedure above.  
2.  
3. Pump will operate when air pressure is alternately  
applied to push type connectors (16).  
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.  
Be sure the pump is  
properly grounded.  
Read Fire and  
Explosion Hazard  
on page 3.

4. Check all fittings to be sure they are tight. Use a  
compatible liquid thread sealant on all male  
threads. Tighten the fluid inlet and outlet fittings  
snugly. Do not overtighten the fittings into the  
pump.  
Pump Shutdown  
At the end of the work shift, relieve  
the pressure as described in Pres-  
sure Relief Procedure at left.  
5. Place the suction tube (if used) in the fluid to be  
pumped.

Maintenance  
Lubrication  
Tightening Threaded Connections  
The air valve is lubricated at the factory to operate  
without additional lubrication. If you want to provide  
additional lubrication, remove the hose from the pump  
air inlet and add two drops of machine oil to the air  
inlet every 500 hours of operation or every month.  
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 20.  
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.  
Preventive Maintenance Schedule  
Establish a preventive maintenance schedule, based  
on the pump’s service history. This is especially impor-  
tant for prevention of spills or leakage due to dia-  
phragm failure.  
Flushing and Storage  
Flush the pump 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 you store it for any length of time.  
Read Pressure Relief Procedure  
on page 10.

(15) to remove the other fluid-side diaphragm plate  
(133) from the diaphragm shaft.  
7. Repeat step 5 for the other end of the diaphragm  
shaft (15), and torque the diaphragm shaft screws  
(140) to 80 to 90 in-lb (9 to 10 N-m) at 100 rpm  
maximum.  
6. Remove the screws (141) and air covers (136),  
and remove all old gasket (12) material from the  
ends of the center housing (11) and the surfaces of  
the air covers.  
8. Install the muffler (3).  
7. Remove the diaphragm shaft u-cups (16) and pilot  
pin o-rings (1).  
When you install the vee clamps in step 10, orient the  
center housing (11) so the air inlet is approximately  
45_ above horizontal and the muffler (3) is approxi-  
mately horizontal.  
8. Inspect all parts for wear or damage, and replace  
as necessary.  
9. Apply thin, even film of grease to inside of vee  
clamp (109).

10. Position the fluid covers (101), install the vee  
clamps (109) around the fluid and air covers,  
install the grounding strip on the vee clamps, and  
torque the vee clamp nuts to 80 to 90 in-lb (9 to 10  
NSm). See Torque Sequence, page 20.  
1. Insert a diaphragm shaft u-cup (16) and a pilot pin  
o-ring (1) into the end of the diaphragm shaft bore  
of the center housing (11).  
NOTE: Make sure the lips of the u-cup face out of  
the center housing.  
11. Make sure all the check valve parts are in place.  
See Fig. 6 on page 15.  
2. Line up the holes in the gasket (12) with the holes  
in the end of the center housing (11), and use six  
screws (141) to fasten an air cover (136) to the  
end of the center housing (11). Torque the screws  
to 35 to 45 in-lb (4.0 to 5.1 N-m).  
12. Install the manifolds (102), and torque the manifold  
bolts (105) to 80 to 90 in-lb (9 to 10 NSm). See
