What is Net Positive Suction Head (NPSH) for Centrifugal Pumps?

Written by Welcome on June 23, 2026

Net Positive Suction Head (NPSH) is the amount of pressure available at a pump’s suction above the liquid’s vapor pressure. It indicates whether sufficient pressure exists to prevent cavitation. To avoid cavitation, the NPSH Available (NPSHA) in the system must be greater than the pump’s NPSH Required (NPSHR). What is NPSH in Centrifugal Pumps? Net […]
