NPSH margin ensures the pump meets the requirements for reliable operation. This course discusses the benefits to pump longevity when the NPSHA is greater than the NPSHR by a suitable margin and suggests margins for specific applications. Covered in this course are rotodynamic general purpose pumps with absorbed power levels up to 4 MW (5,300 hp) and impeller inlet tip speeds less than 40 m/s (130 ft/s).

Description Phrase

An extensive standard to understand NPSH margin and how it applies to rotodynamic pumps.

Roll Over Copy

ANSI/HI 9.6.1 serves as a guideline for NPSH margin for rotodynamic pumps with absorbed power levels up to 5300 hp and impeller tip speeds less than 130 feet per second. The purpose of this guideline is to establish recommended net positive suction head available (NPSHA) above the published NPSH required (NPSHR) that will lead to acceptable pump performance and service life.

Because cavitation is unavoidable in pump operations, understanding how to reduce it using NPSH calculations is necessary to maintain pump functionality and health.
