Vertical Sump Pumps are used in applications where the liquid to be pumped cannot be primed or a conventional priming arrangement is not fail-proof. The extended shaft in these pumps drives the impeller, the liquid is pumped out through the delivery pipe. The pumps are manufactured in materials like Cast Steel, SS-316, Alloy-20 and its combinations and upto a maximum depth of immersion of 3.5 meters.
These pumps are used in applications like effluent pumping, transfer of Sulfuric acid etc.
