Pump Installation
After removing the pump from its shipping
carton, attach a suitable suction tube or hose
to the pump fluid entry port.
Caution:
Performance will be af-
fected by a suction path seal that
is not air tight.
If mounting to a reservoir bung port, thread
the pump bung adapter into the bung thread
on the fluid reservoir, lower the pump into
the mounted bung adapter, then tighten. The
suction tube should be submerged in the tank
liquid and should reach to within 1 to 2 inches
from the bottom of the reservoir.
If mounting onto a wall bracket, place the
pump in the bung-mount adapter provided
on the bracket, then tighten the adapter
clamping threads. Attach a wall mount Suction
Assembly Kit to the pump, then lower the
suction tube into the reservoir, adjusting height
to set the end of the tube 1 to 2 inches above
the bottom of the reservoir.
Caution:
Always tighten pump
down securely to avoid damage to
the fluid reservoir, the pump, and
nearby equipment. Be sure to use
only the specified bung adapter.
Provide a drop-tee fitting, 1/2” size or larger, in
the nearby air supply pipeline. From that tee,
install the following pump air line assembly:
•
pipe bushing or adapter (to bring the
line drop size to 1/2” male)
•
1/2" pipe drop to pump level
•
1/2" pipe elbow
•
1/2" shutoff ball valve (having an air
relief vent when closed)
•
1/2" pipe nipple
•
1/2" F-R-L or filter/regulator assembly
•
1/2" x 3 ft. air hose
•
1/2" air line coupler and nipple.
Attach the air nipple to the air inlet port of
the Giant Jet
™
Pump. During assembly of
the air supply line, be sure to blow out all
foreign materials before making connection to
the pump.
Balcrank
®
recommends that an air line lubrica-
tor be used with turbine oil (viscosity 150-170
SSU @ 100° F) and set at a maximum oil feed
rate of 2 drops per minute of pump operation.
The pump air motor has been coated with
a special synthetic grease at initial assembly
(available as Balcrank p/n 826733) and does
not require additional greasing except during
reassembly after a repair.
Preventive Maintenance
The Giant Jet
™
Pump has been designed
to operate dependably with little required
maintenance. However, to ensure pump
longevity, the following should be observed:
• Keep the fluid free of trash and debris.
Periodically check the pump inlet for
foreign matter and clean when neces-
sary.
• Run the pump at the minimum pres-
sure required to achieve the desired
flow rate.
• Ensure the pump receives clean,
moisture free air. Check and maintain
the system’s air filter on a regular
basis.
• Although the air motor is coated with
synthetic grease upon factory assem-
bly and can run without lubricated air,
Balcrank recommends an in-line F-R-L
be installed in the pumping system.
• Never let the pump run dry of pumped
fluid.
