Operation
WARNING
To reduce the risk of static arcing which could
result in a fire or explosion and serious injury, use
only non-sparking tools if the pump is being as-
sembled or worked on in a hazardous atmosphere.
Pump Assembly
1.
Remove the cotter pin from the connecting rod.
Screw the connecting rod into the air motor rod until
the pin holes align. Install the pin. Bend the ends of
the pin tightly and smoothly around the connecting
rod. This is to avoid scratching the cylinder during op-
eration. Push the displacement rod up and engage
the threads of the upper lug nut in the air motor base.
Hand tighten the lug nut and then secure by tapping
the lug nut with a hammer.
2.
Connect a grounded air hose to the air inlet. Provide
an air regulator to control pump speed and pressure.
To help protect the air motor, provide an air motor lu-
bricator.
NOTE:
If an air motor lubricator is not used, manually
lubricate the motor each day. Close the air
regulator. Remove the air inlet hose and squirt
several drops of SAE 10 motor oil into the air
inlet. Attach the hose and run the pump slowly
for a couple of minutes to distribute the oil.
3.
Connect a suitable hose to the 3/4 npt fluid outlet.
Connect a dispensing valve to the hose.
4.
Connect a ground wire to the pump grounding lug.
Connect the other end of the ground wire to known
ground. See
Grounding
on page 5.
Wet All Internal Parts of the Pump and Hose
A dry pump and hose draws moisture out of the material
being pumped, which contributes to pump clogs. To re-
duce clogging, flush the pump and hose with clean water
before priming it with material.
Regular Operation
1.
Mix the material thoroughly to remove all lumps.
Pay particular attention to the corners and sides of
the mixing container.
2.
Mount the pump in the mixing container.
NOTE:
If the pump was flushed with water, direct the
hose into a waste container until all water is
displaced with material.
3.
Supply air to the pump. Always open the air regulator
slowly and then increase pressure gradually until the
pump is running smoothly. Use the lowest pressure
necessary to give the desired results.
To Stop Dispensing
Shut off the air supply to the pump and
relieve the pres-
