ANSI/HI 9.6.9-2013 Rotary Pumps – Guidelines for Condition Monitoring

This version of the standard has been superseded. PDF copies remain available for purchase.


This guideline discusses some of the indicators that can be monitored or reviewed on rotary pumps to predict and identify
pump failure modes. Common means of measuring those indicators have been defined. Control limits have been recommended,
where appropriate, for those indicators whose limits are not defined in other Hydraulic Institute Standards. This guideline is intended to give the pump user a tool for condition monitoring of rotary positive displacement
pumps, but does not directly address process management systems.

End users and those who oversee the operation of pumps would benefit from this standard. Readers will learn about monitoring and control system concepts, recommendations on frequency of monitoring factors related to potential pump failure including temperature, leakage, pressure, rate of flow, speed and failure modes and indicators.
