The Importance of Pump Wear Ring Clearances

May 9, 2025
The pump wear ring clearance affects many of the factors that reduce pump life. Calculating and trending this clearance will indicate the pump’s remaining useful life and answer that age-old question – will my pump make it to the next outage?

The wear ring is an important component in the overall pump design and affects many of the factors that reduce pump life, such as high vibration and degraded performance.

This white paper explores why wear ring clearances are so important and how they can be used to determine asset health, including: 

  • The effect of wear ring clearances on pump stiffness and damping
  • Methods for maintaining design wear ring clearances during operation
  • How to calculate wear ring clearance using field data
