LUBRICATION
Ingersoll-Rand No. 50
Ingersoll-Rand No. 100
Before placing a Pump in service:
Remove the Oil
Chamber Plug and fill the oil chamber in the Back-
head with oil. Inject about 3 cc of oil into the air inlet
before attaching the air hose.
After each four hours of operation,
Unless an air
line lubricator is used, replenish the chamber in the
Backhead with oil.
The use of an air line lubricator is recommended
for lubricating the Pump motor.
After each forty hours of operation,
or as experi-
ence indicates, pump 10 or 15 strokes of grease from
No. P25-228 Grease Gun into the Grease Fitting on
the Motor Housing.
Ingersoll-Rand Sump Pumps can be completely sub-
merged but a watertight exhaust conduit to the sur-
face of the sump liquid should be maintained at all
times.
Under no circumstance should hose smaller than
1” ID be used as it will restrict the exhaust and im-
pair the efficiency of the Pump.
When pumping from a ditch or sump, set the Pump
on a board or flat stone or suspend it a few inches
off the bottom of the sump. The less mud, sand and
gravel pumped, the longer the Pump will last.
If the water is very dirty, protect the Pump by setting
it in a mesh basket, or screen it in by some other
method.
Should the Inlet become clogged, turn off the air
supply and disconnect the air supply hose and lift the
Pump from the water. Water running back through
the discharge hose will usually flush the dirt from the
Inlet.
IMPELLER ADJUSTMENT
For the most efficient operation of the Pump, par-
ticularly against high heads, it is necessary that the
clearance between the Impeller and the Impeller
Cover be limited. This clearance is set at 0.010” at
the factory. When, due to wear, this clearance has in-
creased to about 1/32”, an adjustment can be made
by removing enough of the Impeller Cover Shims
to obtain the original 0.010” clearance. This simple
adjustment will prolong the life of the Impeller and
maintain the high efficiency of the Pump. The Impel-
ler Cover Shims are different colors to identify the
various thicknesses.
White is 0.025”, pink is 0.015”,
brown is 0.010”, blue is 0.005” and green is 0.003”.
Impeller Shims are used as required between the
Impeller and the Impeller Spacer to provide running
clearance between the Impeller and the Housing.
When assembling Pump, install only enough Impel-
ler Shims to permit the Impeller to rotate without
any drag.
