Pump Rings/Wear Rings

Centrifugal pumps contain rotating impellers within stationary pump casings. Wear rings are replaceable rings that are attached to the impeller and/or the pump casing to allow a small running clearance between the impeller and the pump casing without causing wear of the actual impeller or pump casing material.
The rotating wear rings on the impeller are termed impeller wear rings and stationary wear rings inside the casing are termed as case wear rings.
