Non-Metallic Wear Rings

Can anyone please list out few non-metallic materials used for Wear Rings in Submersible Multistage pumps (Water Applications)?


The materials I am most familiar with are PEEK, Vespel (CR-6100), Torlon, Florostint, Graphaloy and carbon graphite. We occasionally use pure Teflon. Specific to wear rings and not other wear parts, PEEK, Vespel, Torlon and Graphaloy are the most common choices.

I am not an expert on how these parts are made, however most of them are stocked in bars (or tubes) and we machine the parts in our shop.

Above is a snippet.

@JJPellin, Thank you for being so helpful to others with your thoughtful reply.
