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.
