How does slurry pump work

A slurry can be a mixture of virtually any liquid combined with some solid particles. The combination of the type, size, shape and quantity of the particles together with the nature of transporting liquid determine the exact characteristics and flow properties of the slurry.

There are a large number of differing pump types used in the pumping of slurries. Positive displacement and special effect types such as Venturi eductors are used but by far the most common type of slurry pump is the centrifugal pump. The centrifugal slurry pump utilises the centrifugal force generated by a rotating impeller to impart energy to the slurry in the same manner as clear liquid type centrifugal pumps. However, this is where the similarities end. Centrifugal slurry pumps need to consider impeller size and design, its ease of maintenance, the type of shaft seal to be used and the choice of the optimum materials. This is needed to withstand wear caused by the abrasive, erosive and often corrosive attack on the materials. Many other important considerations are also required.
