SPARE PARTS
A set of ball bearings, a set of wear rings and a set of mechanical seal 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 pump 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.
