Slurry pumps have been designed for pumping liquid containing solid particles. Slurry pumps changes in design and construction to adjust to multiple type of slurry which varies in concentration of solids, size of solid particles, shape of solid particles, and composition of solution. Dynamically balanced Hi-Chrome impellers are used for reliable operation which is basically white iron with 25% chromium added to make it less brittle. Slurry pumps are widely used in transport of abrasive solids in industries such as mining, dredging, power and steel. Slurry pumps have split casing or metal lined casing and rubber line casings are also used for certain application where the solid particles are small.
