Water is a constant threat to mining, whether it enters a mine through infiltration or comes from a storm. Mine operators must be able to manage the water where it is known to exist and quickly alleviate the problems associated with it when it rises unexpectedly. Mine dewatering pumps generally need to pump water horizontally-from a smaller sump to a larger sump-or vertically from the bottom of the pit up to the elevation of the mine, and then horizontally to a discharge point. The pumps most commonly found in mine operations include vertical turbine pumps, electric and hydraulic submersible pumps, horizontal multistage centrifugal pumps and horizontal single-stage centrifugal pumps.

 

 

 

 

Horizontal centrifugal pumps can be multistage, i.e., multiple impellers on a common shaft enclosed in the same pump casing. These pumps generate increased pressure as the discharge of one enclosed impeller is routed to the suction of another enclosed impeller within the casing. Enclosed impellers limit the solids handling sizes of these pumps. In addition, and much like their vertical turbine counterparts, the efficiency and effectiveness of horizontal multistage pumps is dictated by the life of the wear rings and thin, multi-vane impellers.
