Scope of Standard: ANSI/HI 9.6.7-2015 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 n_s = 60, (N_s = 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.

Content: Viscous correction factors and methods for determining them, procedures to estimate effects of viscosity on pump performance, viscous liquid performance correction limitations, methods for estimating net positive suction head required, pump design effects, sealing issues and more.

Who Should Buy This Standard: Pump OEMs who must learn how to test pumps to calculate the difference in performance between water and oil or other viscose materials. Pump users can use standard to evaluate different pumps based on their performance in water and other viscose liquids.
