Slurry pump vs mud pump

Find the best position that allows the pump to run as slowly as possible (to reduce wear) but fast enough to prevent solids from settling and clogging the piping.

- By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.

One problem with centrifugal pumps is that the velocity and shear forces within the pump may damage the slurry/solids. Typically, twin-screw pumps cause the least damage to solids in the slurry.

Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.

Flushing is defined as a fluid which is introduced into the seal cavity on the process fluid side, close to the seal face, and is normally used to cool and lubricate the seal face.
