Nettet4. jun. 2013 · One of the most important lines on a pump performance curve is the Net Positive Suction Head (NPSH) curve. Discreetly applied either below or above the pump performance and efficiency curves, this single plotted line is the key to avoiding cavitation. Required NPSH or NPSHR for a given pump increases with flow. NettetThe characteristic curves of centrifugal pumps plot the course of the following parameters against flow rate (Q): head (H) (see H/Q curve ), power input (P), pump efficiency (η) and NPSHr, i.e. the NPSH required by the pump. The characteristic curve's shape is primarily determined by the pump type (i.e. impeller, pump casing or specific speed.
