Basic use of wearing rings in centrifugal pump

2021-3-2 · Why wearing ring change in centrifugal pump? To improve the performance of the centrifugal pump and reduce noise and vibration within the pump, when the clearance between both wear rings exceeds twice of its original clearance value (as per equipment vendor recommendation) then the wearing needs to change. This is the thumb rule for change.
