What is NPSH and mention centrifugal pump parts?

Question

Accepted Answer

NPSH is the Net Positive Suction Head required by a centrifugal pump to avoid cavitation. Centrifugal pump parts include impeller, casing, shaft, bearings, and seals.

NPSH is the measure of the pressure required at the suction port of the pump to avoid cavitation.
Cavitation occurs when the pressure at the suction port drops below the vapor pressure of the liquid, causing the formation of vapor bubbles that collapse when they reach the high-pressure region of the impeller.
Centrifugal pump parts include the impeller, which rotates and imparts energy to the fluid, the casing, which directs the flow of fluid, the shaft, which connects the impeller to the motor, the bearings, which support the shaft, and the seals, which prevent leakage.
The design of the impeller and casing affects the performance of the pump, including its flow rate, head, and efficiency.
Proper maintenance of the pump parts is essential to ensure reliable and efficient operation.
