Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.

3.Basic pump components such as impeller size and design, materials of construction and discharge configuration must be considered to ensure that the pump can withstand the wear and tear caused by abrasive slurries. Slurry pumps are typically larger in size compared to low viscosity liquid pumps and often require more horsepower to operate due to their lower efficiency. Bearings and shafts must also be more robust and durable.

Hydrostatic head - i.e. the height to which the slurry must be lifted in the piping system.

The most important thing here is to determine the pump power required to deliver a specific fluid flow at the desired or required differential pressure. Consider the following.

Depending on your own requirements, propeller seals, mechanical seals or packing seals can be used.

The dredge pump is designed to draw sediment, debris and other hazardous materials from the surface layer into the suction pipe and transport the material through the pipe to the discharge site. The pump must be able to handle common solid debris of various sizes that can pass through the pump, thus minimizing the downtime required for cleaning.
