Engineering classification of slurry is more complex and involves concentration, particle size, shape and weight in order to determine abrasion severity.
Many factors and corrections to the duty point affect brake horsepower and wear.
The peripheral speed of the impeller is one of the main features and classification of slurry pumps.
Slurry pumps are widely used in transport of abrasive solids in industries such as mining, dredging, and steel.
The most common metal alloy used to build slurry pumps is known as "high chrome", which is basically white iron with 25% chromium added to make it less brittle.
