Impeller Adjustment
For the most efficient operation of the pump, particularly against high heads, it is necessary that
proper Impeller clearance be maintained.
1. Pumps are assembled at the factory with a sufficient quantity of Suction Seal Shims to
provide 0.010" clearance between the faces of the Impeller and the Suction Seal. When, due
to wear, this clearance has increased to 0.032" (1/32"), remove enough Shims to obtain the
original 0.010" clearance.
2. If decreased efficiency is noted, remove the Impeller and slip some of the Impeller Shims
from the Rotor. Replace the Impeller and tighten the Impeller Nut. Rotate the Impeller. Repeat
this procedure until enough Impeller Shims have been removed to cause a slight drag, then
add one 0.010" Shim. Adjust the clearance between the Impeller and the Suction Seal (as
explained in the preceding paragraph) whenever Impeller Shims have been removed.
Operation
Always use an Exhaust Hose and be certain the free end of the Hose is kept well above the
surface of the liquid.
Do not allow the pump to operate at free speed (not submerged) for long periods of time. The
frictional heat generated will damage the composition sealing members.
Prevent dirt from entering the pump. When pumping from a ditch or natural sump, set the pump
on a board or flat stone or suspend it a few inches from the bottom of the sump.
Arranging a wire screen around the inlet or setting the pump in a wire basket is also
recommended. If the inlet becomes clogged, stop the motor and lift the pump from the liquid.
Liquid flowing through the discharge line will usually flush the obstruction from the inlet.
If the pump is stopped while pumping dirty liquids, gravel washed back through the pump by
the liquid in the discharge line may sprag the impeller and prevent the motor from starting
when the air is turned on. If the gravel cannot be dislodged by jarring or striking the pump with
a wooden block; make sure that the air is turned off, remove the air line from the pump, remove
the Inlet and rotate the Impeller by hand.
Be certain the Governor Valve slides freely in the Governor Valve Bushing. A sticking Governor
Valve is the most common cause of erratic motor speed. A loose, sloppy fit resulting from a badly
worn Valve or Bushing produces the same effect.
Ingersoll Rand Sump Pumps can be completely submerged but a watertight exhaust conduit
to the surface of the sump liquid should be maintained at all times. Under no circumstances
should hose smaller than 1 inch internal diameter be used as it will restrict the exhaust and
impair the efficiency of the Pump.
Parts and Maintenance
When the life of the tool has expired, it is recommended that the tool be disassembled,
degreased and parts be separated by material so that they can be recycled.
The original language of this manual is English.
Tool repair and maintenance should only be carried out by an authorized Service Center.
