Larger impellers made of more material. This is to compensate for the wear and tear caused by abrasive slurries.

What is 'slurry'?

Chromium White Iron, Super High Chromium Hypereutectic White Iron, Low Carbon High Chromium Alloy, Carbon Steel,

A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.

Another important target=_blank title=Part of the Slurry Pump>part of the slurry pump is its casing, which bears all the pressure. The slurry pump casing should have a large clearance between the impeller and the diversion angle to reduce wear and prevent large solid particles from getting stuck. Due to the extra space, there is more recirculation in the slurry pump casing under various operating conditions. Again, this accelerates wear compared to typical pumps.
