A Slurry pump is a type of centrifugal 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.
Types
Grouped by
- 1. impeller quantity: single stage and multistage slurry pump
- 2. shaft position from the horizontal: horizontal and vertical slurry pump
- 3. impeller suction way: single suction and double suction slurry pump
- 4. pump casing structure: solid casing, horizontal split-case, and vertical split-case slurry pump
Industries
Slurry pump are widely used to transport corrosive/abrasive and high concentration slurry in many industries such as: Gold, Silver, iron ore, Lead&Zinc, Mineral sands, Tin, Steel, Titanium, Molybdenum, Copper, Electric Utilities, Oil Shale, Water&Sewage Utilities, Building areas, Coal, Sand&Gravel, Tobacco, Agriculture (hog, poultry, dairy manure), etc.
What slurry pump to use
- Determine before selecting appropriate slurry pump:
- Capacity
- Head
- Solids handling capacity
- Efficiency and PowerSpeed
- 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 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
Drive Type
V-belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices
