A slurry pump is a type of pump designed for pumping liquid containing solid particles. Slurry pumps change in design and construction to adjust to multiple types of slurry which varies in the concentration of solids, size of solid particles, the shape of solid particles, and composition of the solution. Slurry pumps are more robust than liquid pumps; they have added sacrificial material and replaceable wear parts to withstand wear due to abrasion.
Centrifugal, positive displacement and vortex pumps can be used for slurry. Centrifugal slurry pumps can have between bearing-supported shafts with split casing or rubber- or metal-lined casing. Configurations include horizontal, vertically suspended, and submersible.
The slurry is usually classified according to the concentration of solids. Engineering classification of slurry is more complex and involves concentration, particle size, shape, and weight in order to determine abrasion severity.
