The impellers of slurry pumps are made of materials resistant to corrosion by the medium. The choice of the material depends on the nature of the slurry the pumps will handle.
The casing of the slurry pumps have protective liners made from elastomers such as rubber to protect the casing from the medium.
Centrifugal, pumps, gear pumps and peristaltic pumps can be used as slurry pumps.
