ANSI/HI 9.8-1998 Rotodynamic Pumps for Pump Intake Design

This version of the standard has been superseded. PDF copies remain available for purchase.


This standard applies to the design of new intakes as well as the modification of existing designs used with rotodynamic
pumps. It outlines standard intake designs based on certain criteria, beyond which requires a physical model study to be in compliance with the standard. Ideally, the flow of liquid into any pump should be uniform, steady, and free from swirl and entrained air.  Lack of uniformity through inlet connection can result in pumps not operating to optimum design condition, at a lower hydraulic efficiency and result in poor reliability. 

Those involved in the water and wastewater, process service, petrochemical service and other industries that funnel water and other liquids through intake connections to a pump would benefit from this standard.
