Scope

This guideline is for rotodynamic pumps, including both sealed and sealless pump designs, as stated in each section.

Purpose

This document is intended to give the pump user a tool for condition monitoring of the pumps in their systems but does not directly address process management systems.

UPDATE FOR ANSI/HI 9.6.5-2022:

This guideline offers fundamentals of condition-based maintenance for rotodynamic pumps, including monitoring and failure detection techniques for both sealed and sealless designs. Pump condition monitoring methods and control limits are outlined for the monitoring of power, temperature, corrosion, leakage, pressure, vibration, lubricant, flow rate, pump speed, and bearing wear monitoring.

This is a revision of the 2016 guideline, which includes some major changes in the document listed below   
1. A new section on Pump erosion wear monitoring has been added.
2. Condition based maintenance has been incorporated in the standard.
3. Critical & Safety condition monitoring has been added.
