Slurry pumps can handle high slurry concentrations but the flow passages experience excessive wear. The service lives of traditional slurry pumps in mines can be as short as 20–30 days, which creates significant problems for the mining industry [4], [5]. Many authors have undertaken studies of the two-phase flow in slurry pumps.
The CFD-code FLUENT, version 5.4, has been used for the flow analysis of two test pumps of end-suction volute type: one of low specific speed and one of medium specific speed.
Overall, for slurry pumps, the efficiency under cylindrical particle two-phase flow is better, but its wear is more serious. (5) Based on the analysis of motion characteristics of particles with different shapes in the pump, it is helpful to optimize the design of the slurry pump and the results are referable for other solid–liquid pumps.
The impeller in a slurry pump is designed to optimize the passage of abrasive solids while considering erosive wear that will affect performance. Therefore, they are designed compared to more conventional impellers used with clear liquids. Both closed and semi-open impellers can be used for slurry applications. "Clearing" or "expelling" …
The most common type of slurry pump is the centrifugal pump with a larger impeller, thicker vanes, and more horsepower. The working of the centrifugal slurry pump is quite simple. They use the centrifugal force generated by a rotating impeller which pushes the slurry to move through the discharge. When choosing a centrifugal slurry pump the ...

Features. Features for slurry pumps include leveling (on / off control devices), self-priming, and thermal overload protection. Non-clog, plug-in, reversible, and run dry capable models are also available. With self-priming slurry pumps, a sufficient vacuum is created to draw fluid into the inlet without additional assistance.
