• HPU-O-3-M

    The system is an open loop hydraulic system.

    The hydraulic power unit (HPU) is a skid mounted free-standing hydraulic power pack that is designed to feed the hydraulic ringline.


    HPU skid
    The HPU has a self bearing steel frame designed for bolting to deck, including four lifting brackets for handling. The hydraulic oil tank is made of stainless steel, while the skid is made of carbon steel.

    Control System and PLC Software
    The control system is located in a separate cabinet on the unit and the unit is manually operated locally at the skid.

    Continuous Oil Circulation System
    The circulation circuit provides cooling and filtration of the hydraulic oil and flushing of the ringline pumps.

    Axial Piston Pumps
    Efficient and compact design with adjustable displacement
