A Better, Faster Way to Source Pumps

Hydraulic Institute updates standard on viscosity correction

The Hydraulic Institute has updated the 2004 ANSI/HI standard on viscosity correction and published the Effects of Liquid Viscosity on Rotodynamic Pump Performance ANSI/HI 9.6.7-2010, according to a news release.

The standard was revised in 2004. It’s now been updated to provide better results and it’s easier to use for people involved in pumping liquids that have a higher viscosity than water.

Improvements in the 2010 version included refined mathematics for better results, editorial changes for easier reading and clarifications that improve accuracy.

The upper limit of the flow range has been increased to 410 m3/h (1800 gpm) in the updated standard.

HI Pump Standards are reliable, widely accepted references for anyone involved in pumps, including users, consultants, contractors, construction firms, pump manufacturers, seals, motors, instrumentation, controls, and pump software developers and systems integrators. HI periodically introduces new Standards based on industry needs.
