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

The standard applies to evaluation of vibration on rotodynamic pump applications when the vibration measurements are made on non-rotating parts (bearing housing vibration). It includes general criteria for acceptance tests in the field or at a manufacturer’s facility.
