Hydraulic Submersible (HPU, HST)


Thompson Pump's Hydraulic Submersible pump series handles solids up to 4.25 inches, flows to 7,200 GPM and heads up to 240 feet. Designed to run dry without damaging components, this hydraulic pump is constructed from heavy-duty cast iron and steel for durability, reliability and maximum versatility. The pumps are ideal for pit and quarry dewatering and any other applications that require the transfer of liquids that contain solids. Hydraulic Submersible pumps are designed to eliminate suction lift limitations that occur when pumping out of deep excavations that exceed 25 feet in depth. The heavy-duty cast iron and steel construction, which includes replaceable wear parts and a replaceable stainless-steel cut-water, is ideally designed to pump abrasive materials.
