Slurry Pumps

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 type of slurry which varies in concentration of solids, size of solid particles, shape of solid particles, and composition of solution. Slurry pumps are more robust than liquid pumps; they have added sacrificial material and replaceable wear parts to withstand wear due to abrasion.

Both centrifugal and positive displacement pumps can be used for slurry. Centrifugal slurry pumps can have between bearing-supported shafts with split casing and a rubber or metal-lined casing. Configurations include horizontal, vertical suspended and submersible.

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.

Slurry pumps are widely used in transport of abrasive solids in industries such as sand, mining, dredging, and steel. They are often designed to be suitable for heavy-wearing and heavy-duty uses. Depending on the mining process, some slurries are corrosive which presents a challenge because corrosion-resistant materials like stainless steel are softer than high-iron steel. The most common metal alloy used to build slurry pumps is known as "high chrome", which is basically white iron with 27% chromium added to make it less brittle. Rubber lined casings are also used for certain applications where the solid particles are small.
