Centrifugal Pump Operation:

Improper operation of centrifugal pumps could result within damage to the pump and loss of function of the system in which the pump is installed in. It is supportive to know what conditions could lead to pump damage to permits better understanding of pump operating process and how the procedures aid the operator in preventing pump damage.

DEFINE the following terms:

a. Net Positive Suction Head Available

b. Cavitation

c. Gas binding

d. Shutoff head

e. Pump runout

STATE the relationship among net positive suction head available and net positive suction head needed in which is must to prevent cavitation.

LIST three indications which a centrifugal pump might be cavitating.

LIST five changes that could be made in a pump or its surrounding system which can decrease cavitation.

LIST three effects of cavitation.

DESCRIBE the shape of the features curve for a centrifugal pump.

DESCRIBE how centrifugal pumps are protected from the conditions of dead heading and pump runout.
