Slurry pumps are heavier and more robust versions of centrifugal pumps that are used to handle tough or abrasive applications. A standard centrifugal pump is used mainly for forcing out clear liquids, whereas a slurry pump is used for the hydraulic transport of solids.
The term "Slurry Pump" refers to all of the devices used in the transport of solids. More specific names are given to them based on the size of the solid being transported or based on its particular use. To know more about slurry pumps, you can simply visit this site.
The slurry pump is used to transport mud, clay, silt, and sand in the size range of solids up to 2 millimeters. Sand and gravel pumps handle the transporting of shingles and gravel in the 2 to the 8-millimeter range. Additionally, gravel pumps may transport solids up to 50 millimeters in size. Dredge pumps are used to handle solids up to and exceeding 50 millimeters.
Specific names are also based on the application or use. Froth pumps handle frothy slurries, mainly in flotation. Carbon transfer pumps provide the gentle hydraulic transportation of carbon in pulp and carbon in leach circuits. Sump pumps are mainly operating pumps from floor sumps that have submerged houses but dry bearings and drives. Submersible pumps, as the name implies, are fully submersed, including the housing and drive.
Depending upon the application, the slurry pump can be installed dry, semi-dry, or wet. Most horizontal slurry pumps are installed dry. In this case, the bearings and the drive are kept out of the slurry, and the wet end is closed. The slurry is free-standing and clear of any liquids. The vertical tank may also be installed dry. This has an open sump with the pump casing mounted directly under the tank. The slurry is fed from the tank and expelled horizontally. No submerged bearings are required in this design.
