Hydraulic Updates ANSI/Hi Pump Intake Design Standard

The Hydraulic Institute (HI) has updated the 1998 edition of the ANSI/HI standard on pump intake design and published ANSI/HI 9.8–2012 Rotodynamic Pumps for Pump Intake Design. Developed by experts in sump design, researchers specialized in fluid flow dynamics, and senior engineers representing pump manufacturers and the end-user community, this standard enables designers, owners and users to configure functional pumping facility designs and provides remedial measures for problem intakes.

The standard provides a flowchart to serve as a guide to the use of this standard and can be used to locate the appropriate section(s) in the standard. Among the intakes included in this standard are rectangular intakes, formed suction intakes, circular pump stations, can vertical turbine pump intakes and unconfined intakes.

Other topics of interest in this standard include inlet bell design, the required submergence for minimizing surface vortices and alternate formed suction intake designs.

The updated standard is available for purchase at the HI eStore for $225 in both hardcopy and pdf formats.
