Slurry Pump Pretoria

A slurry pump pretoria is a type of pump designed for pumping liquid containing solid particles. Centrifugal, positive displacement, and vortex pumps can be used for slurry. Centrifugal slurry pumps can have between bearing-supported shafts with split casing or rubber- or metal-lined casing.

How does a slurry pump work? It has an inlet at the suction of the pump that increases the speed of the slurry through the vanes of a rotating impeller, producing centrifugal force which sends the slurry through the casing to the discharge. The casing is a horn-shaped element that transfers speed into pressure. Both centrifugal and positive displacement pumps can be used for slurry. Centrifugal slurry pumps can have between bearing-supported shafts with split casing or rubber- or metal-lined casing. Configurations include horizontal, vertical suspended and submersible.

Selection of slurry pumps is more difficult than selection of pumps for water and liquids. Many factors and corrections to the duty point affect brake horsepower and wear. Root-dynamic Centrifugal Slurry Pumps provides methods for calculation of slurry pumps. The peripheral speed of the impeller is one of the main features and classification of slurry pumps. Speed must be in accordance with the slurry type classification (abrasion classification) in order to maintain a reasonable life in service due to high abrasion of solids.

Before selecting an appropriate slurry pump pretoria the engineers considers capacity, head, solids handling capacity, efficiency and power, speed and NPSH.

Why is slurry so dangerous? Gases are produced by bacteria during the decomposition of slurry, and these can kill people and animals almost instantly. Heavier than air, the gas settles in a cloud over the top of the slurry during mixing. Bending down into the gas cloud even briefly can cause unconsciousness. Slurry is usually classified according to the concentration of solids. Engineering classification of slurry is more complex and involves concentration, particle size, shape and weight in order to determine abrasion severity. For engineering selection of slurry pumps, slurry is classified as class 1, class 2, class 3 and class 4.
