gear pump internals for abrasive slurry

gear pump internals for abrasive slurry

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)

RE: gear pump internals for abrasive slurry

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

A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
