What is the usng of Wear ring ?
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.
The function of the wear ring is to help keep the piston centered, which allows for even wear and pressure distribution on the seals. Popular wear ring materials include glass filled Nylon, bronze filled PTFE, glass filled PTFE, Phenolic and PEEK. Wear rings are used in both piston and rod applications. Wear rings are available in butt cut, angle cut and step cut styles
