PARSIPPANY, NJ – 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.
The document will be supplemented in the future by a new ground-breaking guideline document, Dynamics of Pumping Machinery, currently being drafted.
