ANSI/HI 9.6.7-2021

Rotodynamic Pumps - Guideline for Effects of Liquid Viscosity on Performance

ANSI/HI 9.6.7 outlines the method for predicting performance of Rotodynamic pumps in Newtonian liquids of viscosity greater than water. The scope of this guideline is the Rotodynamic radial flow pumps of overhung (OH) between bearing (BB) or vertical (VS) type of convential design, within the allowable operating range, pumping Newtonian fluids.
 What's New: The 2021 edition of ANSI/HI 9.6.7 includes editorial changes from prior publications related to standard deviation for correction factors. Additional clarification on the uncertainty of viscous power consumption is included. What You Will Learn/Overall Benefits:
 · Understand the effects of viscous liquids on pump performance related to flow, head pressure and required horsepower
 · Predict the change in pump performance when handling viscous liquids to ensure the correct selection of a pump for use in a specific liquid
  Applicable Markets:  Oil and gas, petroleum refinery, chemicals, pharmaceuticals and any industry using liquids heavier than water.
