Sep 03, 2015

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.
