Current Version: ANSI/HI 9.6.1-2012
Next Version: 2017
Scope: 'This guideline addresses rotodynamic general purpose pumps with absorbed power levels up to 4 megawatts(MW) (5300 horsepower [hp]) and impeller inlet tip speeds less than 40 meters per second (m/s) (130 feet per second[ft/s]). It describes the benefits to pump longevity when the net positive suction head (NPSH) available isgreater than the NPSH required by a suitable margin, and suggests margins for specific applications.

Current Version: ANSI/HI 9.6.3-2012
Scope: 'This guideline applies to rotodynamic (centrifugal and vertical) pump types. It describes the effects of operating a rotodynamic pump at rates of flow that are greater or less than the rate of flow at the pump's best efficiency point (BEP).

Current Version: ANSI/HI 9.6.4-2016
Next Version: 2021
Scope: 'This standard applies to the evaluation of vibration on rotodynamic pump applications absorbing more than 2 kW (3 hp) and of the types as indicated in Figure 188.8.131.52.3.1. It pertains to evaluation of vibration when the vibration measurements are made on nonrotating parts (bearing housing vibration).

Current Version: ANSI/HI 9.6.7-2015
Next Version: 2020
Scope: 'The Hydraulic Institute (HI) has developed a generalized method for predicting performance of rotodynamic pumps on Newtonian liquids of viscosity greater than that of water. This is an empirical method based on the test data available from sources throughout the world. The HI method enables pump users and designers to estimate performance of a particular rotodynamic pump on liquids of known viscosity, given the performance on water.
