Description  more details

Scope of Standard: ANSI/HI 9.6.7 outlines the method for predicting performance of rotodynamic pumps in Newtonian liquids of viscosity greater than water. The standard applies to single and multi-stage rotodynamic pumps having radial impellers ns = 60, (Ns = 3000), handling liquids exhibiting Newtonian behavior, and a kinematic viscosity greater than 1 and less than 4000 centistokes.

What's New: The 2015 version of ANSI/HI 9.6.7 differs from the 2010 version in a few areas. New data has become available as outlined in Section 9.6.7.4.1, including new references in the bibliography. Expanded guidance on the effect of speed versus torque characteristics is found in Section 9.6.7.6.1. 

What You Will Learn/Overall Benefits:

  • Understand the effects of viscose 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 used in a specific liquid

 

Applicable Markets:  Oil and gas, petroleum refinery, chemicals, pharmaceuticals and any industry using liquids heavier than water.
