What is the function of wear ring in centrifugal pump?
Wearing 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.Click to see full answer.

Wearing 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.Click to see full answer. Hereof, what does a wear ring do?Wear rings can be defined as a device used to seal the pressure leakage of the liquid between the inlet of the impeller and the pump casing. Wear rings are typically found on sewage pumps with closed impellers.One may also ask, what are the parts of centrifugal pump? Main Parts of a Centrifugal Pump Impeller. Impeller is a rotor used to increase the kinetic energy of the flow. Casing (Volute). The casing contains the liquid and acts as a pressure containment vessel that directs the flow of liquid in and out of the centrifugal pump. Shaft (Rotor). The impeller is mounted on a shaft. Shaft sealing. Bearings. Beside above, what is the purpose of a lantern ring? The lantern ring is grooved with an oil groove and drilled with holes to allow lubrication to reach the packing material. The lantern ring is also used to distribute cooling water to all packing rings as well as keep the stuffing box clean of containments. .How do you measure ring clearance?Traditionally vernier caliper is used to measure the wear and new clearance of the wear rings. Take the wear rings out of the pump assembly and put on a flat clean surface. Now using a vernier caliper measure the internal and external diameter of the ring.
