ANSI/HI 20.3 presents a simplified method to predict normally attainable efficiency levels at the best efficiency point for selected types of rotodynamic pumps when the rate of flow, total head per stage, net positive suction head available (NPSHA), and the service conditions are known. The standard provides guidelines on the following pump types:
Slurry, end suction
Solids-handling, end suction pumps
Submersible sewage, end suction
Stock, end suction
Horizontal multistage, axial split, segmented ring diffuser barrel
ASME B73, API end suction, end suction - small
End suction - large (greater than 0.3 m3/s (5000 gpm)
API double suction
Double suction, general service
Vertical turbine, mixed-flow and propeller, single and multistage diffuser type
