A slurry pump (or slurry pump) is, in general, a type of centrifugal pump specifically designed for transporting slurries, which are mixtures of solids suspended in liquids—usually water.
It is a specialized pump used to move fluids containing solid particles. These particles can be abrasive, corrosive, or both. The slurry pump is designed to resist wear and clogging, which would be problematic for conventional pumps.
Main applications by industrial sector:
- Mining:
Transportation of ore slurries (iron, gold, copper, nickel, etc.);
Feeding hydrocyclones, thickeners, and flotation;
Dam tailings;
Abrasive slurry and acid slurry.
- Cement industry:
Transportation of limestone slurry;
Mixing mortars and cement slurries.
- Steel industry:
Ore washing circuit;
Slurries containing slag or sand.
- Chemical industry:
Transportation of solutions containing corrosive solids;
Difficult-to-pump chemical suspensions.
- Pulp and paper:
Transportation of wood pulp (fiber slurry);
Cellulose pulp processing.
- Food and beverage:
Processing of fruit, vegetable, or biomass pulp (in some heavy industrial applications).
- Dredging and sanitation:
Dredge pumps for removing silt, sand, and gravel from rivers, canals, and ports.
Most slurry pumps are centrifugal, but there are also versions:
- Submersible.
- Piston/diaphragm (specific alternatives).
- Waterjet/hydraulic (in dredging).
The centrifugal slurry pump is the most common. It uses a high-speed impeller to generate centrifugal force, propelling the solid-liquid mixture through the system. |
