Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.

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.

The winch dredger is usually equipped with a hull-mounted dredge pump, which has an impeller centered at or below the draft line for further production and improved suction efficiency.

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

First, what is a slurry? A slurry is a semi-liquid mixture, usually consisting of fine particles. Examples of slurries can include manure, cement, starch, or coal suspended in water. There are countless other combinations that can be considered slurries. Because of the added particles and thicker consistency, special pump requirements should be considered. A standard pump may be able to handle the fluid, but not as effectively as a properly sized slurry pump.

A variety of factors must be considered to ensure a satisfactory service. Here are tips for choosing the right >pump. In applications ranging from processing to wastewater treatment, plants often have to handle slurries. Handling this mixture of liquids and solids can be challenging and difficult. Some of the key factors in slurry pumping are the size and nature of the solids in the liquid and the type of wear they cause. Another is the corrosiveness of the liquid or mixture.
