PERFIG

PERFIG is a specialized software system for preliminary design and performance prediction of single- and multistage centrifugal and mixed-flow pumps. It calculates design and off-design performance, and can be used to either optimize a new design or analyze an existing design. The geometry allows impellers, vaneless spaces, vaned diffusers, and scrolls, volutes, exit diffusers, or return channels.

A menu-type user interface requires input that includes mass flow, rotor speed, and component geometry. Graphic and tabular output are available for head, hydraulic efficiency, power required, and NPSH. Losses are identified according to 11 separate mechanisms.
