By defnition slurry pumps are a heavy and robust version of a centrifugal pump, capable of handling tough and abrasive duties.
"Slurry pump should also be considered as a generic term, to distinguish it from other centrifugal pumps mainly intended for clear liquids".
Slurry pump – name by duty
The term slurry pump, as stated, covers various types of heavy duty centrifugal pumps used for hydraulic transportation of solids.
A more precise terminology is to use the classifcation of solids handled in the various pump applications.
Slurry pumps cover pumping of mud/clay, silt and sand in the size range of solids up to 2 mm.
Size ranges are:
Mud/clay minus 2 microns
Silt 2-50 microns
Sand, fne 50-100 microns
Sand, medium 100-500 microns
Sand, coarse 500-2000 microns
Sand & Gravel pumps cover pumping of shingle and gravel in the 2-8 mm size range
Gravel pumps cover pumping of solid sizes up to 50 mm
Dredge pumps cover pumping of solid sizes up to and above 50mm.
Slurry pump – name by application
Process applications also provide the terminology, typically:
Froth pumps defne by application the handling of frothy slurries, mainly in ﬂotation.
Carbon transfer pumps defne the gentle hydraulic transportation of carbon in CIP (carbon in pulp) and CIL (carbon in leach) circuits.
Sump slurry pumps, also an established name typically for pumps operating from ﬂoor sumps, submerged pump houses, but having dry bearings and drives.
Submersible slurry pumps, The entire unit, including drive, is submersed.
