The Hydraulic Institute is set to produce the next edition of the standard ANSI/HI 9.6.4, Rotodynamic Pumps for Vibration Measurement & Allowable Values

In order to improve the standard, the ANSI/HI 9.6.4 vibration committee is seeking vibration data from end users. Survey forms have been created to assist in the data collection process for the following type of equipment:

  • Horizontal motor
  • Mono-vane impeller
  • Submersible volute pump
  • Vertically suspended pump
  • Vertically suspended pump with gearbox

Once a survey form is completed, it can be submitted to the attention of Edgar Suarez, Technical Program Manager, via email at or mailed to: 300 Interpace Parkway, Building A, 3rd Floor, Parsippany, New Jersey, United States, 07054. 

Submitters will be recognized as contributors when the next edition of the standard is published.
