Hydraulic Submersibles: Hydraulic Power Unit Submersible Pump Head

Updated Aug 2, 2010

Thompson hydraulic submersible pumps provide a powerful answer when high heads or high lifts become a factor on job sites. Decades of engineering excellence at Thompson have led to the development of our unique variable speed and variable flow hydraulically driven submersible pumps. The power units and pumps are manufactured from heavy-duty cast iron and steel for high reliability. The Thompson design allows for maximum versatility in dewatering applications and pumping materials.
