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.
