Thomson Pumps Hydraulic Submersible Pump Heads

Thompson’s Hydraulic Submersible Pump Heads provide a powerful answer when high heads or high lifts become a factor on job sites, with the ability to handle up to 4.25-inch solids and heads up to 245 feet.

These unique variable speed and variable flow hydraulically driven submersible pumps and power units are manufactured from heavy-duty cast iron and steel for high reliability.

Working Principle

Thompson’s hydraulically driven submersible pumps enable the power unit to remain high and dry while the pump head is submerged in the liquid being pumped. There is no need to worry about suction lift limitations. These pumps are designed to run dry without damage to the components and are engineered to handle liquids from muddy trash-laden water to sewage and sludge.
