Paul,

Yes ceramics can be used.

I have answered a similar question to yours in the "Wear of Venturi" thread below.

Let me know if you need further info.

Paul this is something we have been doing for several years with a high level of success.

We have a proprietary ceramic product unlike most in the fact it will not peel or chip.

If you send me your email address I can send you some photo's as well as other applications .

Pumps, pulley lagging, fans etc.

Regards
