Tried a new pump impeller material on the old cutterhead dredge in Mobile Bay

Switched from the standard polyurethane to a ceramic-coated steel impeller after the third failure in a season, and it's lasted over 800 hours without any noticeable wear, so what's the toughest material you've run in sandy, abrasive conditions?

We had good luck with a hardened chrome alloy on our suction dredge... it outlasted the standard stuff by a huge margin in that shell and gravel mix. That ceramic coating sounds like it's holding up even better though.

Our old dredge wore out three standard linings before we gave up on them.
