pump for slurry, rubber lined vs alloy vs plastic
(OP)
We have rubber lined pumps in our wastewater system. They handle water with about 25% fine solids. pH is typically ~7, but it seems there may be occasional excursions or variances in the mud bed. The liner life is short (~ 6 months) and the liners are expensive (2-3k, parts only). I suspect there are occasions where it briefly runs dry, I think a thermal shutdown might help on that. I also suspect there are occasionally chunks that pass through, and gouge the liner. This leads to high local wear. I am considering a hard metal of high chrome (worthington) or Cd4MCu (gorman-rupp). The vendors I deal with normally don't have anything in a thermoplastic, so I don't even really know what's out there. I saw Vanton in another thread, but their site is down. Any input? Thanks.

If your slurry is abrasive, plastic pumps may be a very good way to go. Plastic pumps actually have much better resistance to abrasion than lined or even metal pumps. Vanton published an excellent technical article on this topic several years ago that I can forward to you.
What is your flow rate and pressure for this application? How big are the solids that you believe are passing?

Flowrate, about 300gpm, head, around 60 to 100ft, size, about like fine sand, but I think we get an occasional damaging chunk, or perhaps even a loose bolt or other trash. They draw on an open top clarifier pond. Once the liner is nicked, it goes quickly.

Take a look at a brand named Discflo. They hold up quite well. Quite a few Steel mills are using them to pump their treated chemical waist with little or no maintenance.

You may also want to look into Toyo slurry pumps. They offer fully inclosed and recessed impeller models that are designed for pumping industrial slurry with solids up to 1".

They withstand quite a bit of abuse in our facility.

Have used these in Bentonite slurry pumping + sand laden sewage sludges, tailing dam dredge applications, etc
Good luck,

Rubber is excellent for your application unless you get sharp objects which tear the liner - then it wears fast. Rubber is also speed sensitive - increased impeller speeds can cause damage.
