What will happen to the pump performance of wearing ring clearances increase?
Select Pump Wear Ring Clearance with Care Such friction results in damaged parts increased heat and vibration, and lower efficiency. It can also increase the pump’s NPSHR and may cause cavitation. For every 0.5” increase of the impeller wear ring OD, the 0.010” diametral clearance increases by 0.001”.
