SP(R) submerged slurry pumps are vertical, centrifugal slurry pumps which are submerged in sump to work. They are designed for delivering abrasive, large particle and high density slurries. These pumps do not need any shaft seal and sealing water. They can also be operated normally for insufficient suction duties. 

Wet parts of type SP pumps are made of abrasion-resistant metal. 

All parts of type SP(R) pump immersed in liquid are lined with rubber. They are suited to transport the slurry which contains non-edge and abrasive particle  (corrosive acid slurry) 

The type with “L” is series of sump pump with extended shaft , which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of the standard pump, so the pump is with both more steady operation and wider application range, but flushing water should be attached to the guide bearing.
The pump inlet has three types.  Standard type with strainer,  suction pipe with strainer,  the inlet with agitator. 

The slurry  pumps are mainly used for handing corrosive, coarse particles and high density slurries, and are widely used in sewage treatment, metallurgy, mining, mineral processing, dredging, de-watering, water treatment, coal washing, mill, cyclone feed, tailing, power, building material…etc. various industrial sites. Our pumps are called different names for different working duties: mineral processing pump, mill discharge slurry pump, booster pump, feeding pump, tailing pump, transfer pump, de-watering screen pump, pressure pump, concentrate pump etc.
