Vertical Slurry Pumps
GTEK SP/SPR vertical sump pump is of vertical cantilevered design with hard alloy wear parts or full rubber covering option which can run continuously in abrasive and corrosive pumping environment.
Description
GTEK SP/SPR vertical sump pump is of vertical cantilevered design with hard alloy wear parts or full rubber covering option which can run continuously in abrasive and corrosive pumping environment. Vertical slurry pumps from GTEK not only provide excellent wear life properties, they also operate efficiently to further reduce operating costs. There are no submerged bearings or packing with a unique high capacity double suction design. Optional recessed impeller and suction agitator are available. GTEK SP/SPR heavy duty sump pumps are available in various standard length to suit different sump length.
Working Principle
Bearing Assembly
The vertical cantilever design with no gland or submerged bearings avoids the need for expensive gland or bearing flushing water.
Back Liner
The opened back liner allows plenty of room for the oversized shaft with slurry to pass through and pump from the top and bottom.The top suction draws the slurry away from the drive end.
Casing
Casings are made of cast high chrome alloy steel with rubber or metal lined option.
Impeller
Double suction impellers create low axial bearing loads,increasing bearing life;
Impellers are available in rubber-lined and metal-lined option.
Lower Strainer
The lower strainers keep large foreign material entering the casing.
