NPSH of a pump condenser refers to the Net Positive Suction Head required for the pump to operate efficiently.

• NPSH is a critical parameter in pump selection and operation

• It is the difference between the absolute pressure at the pump suction and the vapor pressure of the liquid being pumped

• If NPSH available is less than NPSH required, cavitation may occur

• Factors affecting NPSH include pump design, fluid properties, and system layout
