The Hydraulic Institute (HI) has published a new American National Standard for Rotodynamic Pumps for Vibration Measurements and Allowable Values (ANSI/HI 9.6.4 - 2009).

HI’s Rotodynamic Pumps for Vibration Measurements and Allowable Values standard applies to the evaluation of vibration on rotodynamic pump applications. It pertains to evaluation of vibration when the vibration measurements are made on non-rotating parts (bearing housing vibration). The general evaluation criteria are included for acceptance tests in field environments or at the manufacturer’s test facility, as appropriate and as defined in the standard.

This document will be supplemented in the future by a new guideline document, Dynamics of Pumping Machinery, currently being drafted by the committee. This standard is based on experiences from pump users and manufacturers, as well as vibration measurements by many companies. Vibration data from both factory test and field test environments have been incorporated into the maximum allowable vibration values. Values are applicable when the pump is installed per Hydraulic Institute or the manufacturer’s specifications.

Copies of Rotodynamic Pumps for Vibration Measurements and Allowable Values will be available for $115 by visiting HI’s e-Store at www.eStore.Pumps.org or by calling the purchasing line at (973) 267-9700 x118.
