Hydraulic Power Units

PRODUCTS > Hydraulic Power Units

Thompson’s Hydraulic Power Unit is designed to eliminate suction lift limitations in excavations or discharge requirements over 25 feet deep. These units are available with variable speed controls and auto-start, and the low oil level/high oil temperature shutdown system and third line for seal blow-out protection.


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.


  • Flows up to 7,300 gpm
  • Discharge heads up to 245 feet
  • Suction lift limitations eliminated with pump head submerged in water
  • Unique 3-line system connecting high-pressure, low-pressure and emergency bypass hoses from the pump head to the power unit
  • Low oil level/high oil temperature auto shut-down system
  • Optional auto-start and variable speed controls
  • Biodegradable lubricants for environmentally sensitive applications
  • 50 feet of hydraulic hose included
  • 12-month limited warranty covers manufacturing defects in materials and workmanship
