LUBRICATION
Ingersoll–Rand No. 50
Never use ordinary cup grease as it emulsifies in water.
Automotive water pump grease is not satisfactory as it is
made for use with hot water and is too hard for use in cold
water.
Always use an air line lubricator with these pumps.
We recommend the following Portable Air Line Lubricator:
For USA – 16LUB16C
For International – No. 16LUB16C
Before starting the pump, unless the air line lubricator is
used, detach the air hose and place 15 – 20 drops of
Ingersoll–Rand No. 50 Oil into the air inlet. Unscrew the
Oil Chamber Plug and fill the oil chamber with oil.
After each eight hours of operation, or as experience
indicates, refill the oil chamber with oil.
Weekly, or as experience indicates, inject Ingersoll–Rand
No. 80 Grease into the three Grease Fittings. Inject 1 to 2 cc
into the Grease Fitting located in the Backhead and the
Fitting nearest the discharge in the Housing. The other
Grease Fitting in the Housing leads to the grease chamber
on the automatic lubricator. Pump grease into this Fitting
until grease starts to seep from the Grease Level Valve.

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.
