Centrifugal Pump Wear Rings

Cast rings are found all around us, from jet engines to military equipment. Although a centuries-old design, subpar manufacturing can cause catastrophic failure. Ensure your finished product fits, forms, and functions as intended with high-quality cast rings from U.S. Bronze Foundry & Machine.

What are cast rings?

Cast rings are hard-wearing cylindrical devices supplied in semi-finished and finished conditions. Typically, these rings are bought semi-finished and undergo additional machining to create a final product. Examples of parts made with cast rings include:

  • Bearings
  • Clutches
  • Couplings
  • Drives
  • Flanges
  • Gears
  • Valves
  • Pump Wear Rings

Centrifugal pump wear rings are circular devices that attach to a pump impeller or casing, allowing a small running clearance without causing wear of the actual impeller or pump casing material. These wear rings are designed to be replaced periodically during a pump’s life and prevent more costly replacement of the impeller or casing.
