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 Agriculture (hog, poultry, dairy manure) and are grouped by:
- impeller quantity: single stage and multistage slurry pump
- shaft position from the horizontal: horizontal and vertical slurry pump
- impeller suction way: single suction and double suction slurry pump
- pump casing structure: solid casing, horizontal split-case, and vertical split-case slurry pump
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
bearing 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.
