The D50 power unit is a compact but powerful diesel driven hydraulic power unit for operating a range of equipment. It features a quiet running water-cooled electric start diesel engine mounted in a steel cage frame fitted with controls. Four large antivibration feet are installed at the corners of the frame. The open style allows excellent access for maintenance.

The D50 has a laser cut control panel with valves to control flow to the three hydraulic circuits. Three hydraulic pressure gauges show the working pressures. A large capacity fuel tank is installed in the base of the frame. The hydraulic tank is mounted above the hydraulic pump and fitted with level/temperature gauge, filter and filler/strainer.
