With high working pressures up to 1379barg / 20,000psig, our Hydraulic Power Units (HPUs) are designed to provide high and low pressure filtered hydraulic fluid to - often safety critical - control valves. In the event of a loss of power, stored volume is provided via accumulators to ensure safe and effective operation.

With extensive experience in the design, manufacture and maintenance of hydraulic power units, SMS can deliver solutions to support a variety of production and marine requirements. This includes HPUs to control:

  • production systems incorporating topside and/or subsea control valves
  • barrier fluid valves
  • turret actuated valves and disconnect systems
  • and ballast control valves
