SPARE PARTS
A set of ball bearings, a set of casing rings, and a set of gland packing rings must always be kept at hand to
ensure uninterrupted service from the pump. While ordering for spare parts, always give type, size and serial
number of the pumps as stamped on the name plate.
PUMP TROUBLE
When investigating trouble with Kirloskar pumps, always remember that pumps have been tested at the
factory and are mechanically correct when sent out. Discounting the possibility of damage during transit,
most of the trouble in the field is due to faulty installation. Investigation shows that the majority of troubles
with centrifugal pumps result from faulty conditions on the suction side.
