Hydraulic Power Units

Steady hydraulic pressure and flow

Power systems control station.

Cameron hydraulic power units (HPUs) deliver steady hydraulic pressure and flow to all hydraulic equipment. Fabricated with top-quality components and materials, these HPUs are easy to operate and maintain.

The units feature remote supply-pressure readout, an integrated inspection hatch, and a local tank level and temperature readout. They also have an onboard oil cooling system, including a titanium plate cooler for seawater service, local pressure gauges, and shutoff valves for easy maintenance of the cooler.
