gear pump internals for abrasive slurry

[sulphurConsult]

Any advise on a gear pump that can be utilized for pumping an abrasive slurry that will not wear the internals of the pump? (impeller)

You do not state flow rates, sp.g., pressures, viscosities, etc.
Looking up sulphur bentonite (which I suspect is the solution) on Google leads me to submit the following.

You know how a set of gears mesh (contact each other). It is the residue of the abrasive material interferring (coheasivly) with that meshing of the gears that can/will produce problems. Wearing away at the gears at what ever speed your operating then finally there are no gears and no pump.
For abrasive material pumps look elsewhere, such as diapharam or parastaltic pumps. Do a google search.

Good Luck

Specially-designed centrifugals could handle abrasive slurries. See thread407-69181
