The Hydraulic Institute (HI) publishes the Hydraulic Institute Guideline for Rotodynamic Pump Efficiency Prediction HI 20.3–2015. The guideline is a tool for users, specifiers and purchasers of pumps to understand what variables, design and selection factors affect the efficiency of rotodynamic pumps. Users will learn the application-specific design features that affect pump efficiency and how to calculate the normally attainable efficiency and uncertainty band for the following pump types:
· Slurry, end suction
· Solids-handling, end suction
· Submersible sewage, end suction
· Horizontal multistage & axially split diffuser type
· ASME B73 chemical process
· API end suction
· Large, end suction
· Double suction, API and other
· Vertical turbine, mixed and axial flow, single and multistage diffuser type
The efficiencies shown in the guideline are those generally obtained using common manufacturing practices and are based on a survey of pump manufacturers. Only the best efficiency point (BEP) values are addresses in the guideline.
