Concept
 

A slurry pump is a type of centrifugal pump, lobe pump or peristaltic hose pump in physics principle that increases the pressure of liquid and solid particle mixture (aka slurry), through centrifugal force (a rotating impeller) and converts electrical energy into slurry potential and kinetic energy.

 

Slurry pumps are widely used to transport corrosive/abrasive and high concentration slurry in many industries such as Gold, Silver, Iron ore, Tin, Steel, Coal, Titanium, Copper, Mineral sands, Lead and Zinc. Various other industries include Molybdenum, Electric Utilities, Oil Shale, Water & Sewage Utilities, Building areas, Sand & Gravel, Tobacco and so on.

 

The parameters determined before selecting an appropriate slurry pump include capacity, head, solids handling capacity, slurry gravity, efficiency and power, speed and NPSH.

Components
 

Impeller ：The impeller, either elastomer or high-chrome material, is the main rotating component which normally has vanes to impart the centrifugal force to the liquid. 

 

Casing：Split outer casing halves of cast contain the wear liners and provide high operation pressure capabilities. The casing shape is generally of semi-volute or concentric, efficiencies of which are less than that of the volute type. 

 

Shaft and Bearing Assembly：A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty roller bearings are housed in a removable bearing cartridge.

 

Shaft sleeve：A hardened, heavy-duty corrosion-resistant sleeve with O-ring seals at both ends protects the shaft. A split fit allows the sleeve removed or installed quickly.

 

Shaft Seal：Expeller drive seal, Packing seal, Mechanical seal.

Drive Type: belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices
