Custom Pump Wear Rings / Casing Rings / Impeller Rings Made to Drawings or Samples
Drawing-based Duplex 2205 pump wear ring, casing ring or impeller ring
Drawing-based pump wear rings for casing and impeller positions. In some pump drawings, seal ring is used as a naming variant for this hard part rather than for an O-ring, rubber seal, or mechanical-seal face.
- Casing / impeller rings
- Clearance control
- Stainless / bronze
Application and function
These parts help control clearance between stationary and rotating pump components. In some pump drawings, seal ring refers to a wear-ring-style hard part, not an O-ring, rubber seal, or mechanical-seal face.

Buyer FAQs
Are pump wear rings the same as mechanical seal rings?
No. This page refers to hard pump wear-ring components such as casing wear rings and impeller wear rings. In some drawings, seal ring may be used for this part, but it does not mean an O-ring, rubber seal or mechanical seal face.
Can you make casing wear rings and impeller wear rings?
Yes. RF Machining reviews casing-side and impeller-side ring drawings, materials, clearances and mating-part information before quotation.
What information helps quotation?
ID, OD, width, material, quantity, surface treatment, clearance requirements and mating-part information help engineering review the wear ring correctly.
