Portable hydraulic power unit
Manufacturer: ATOS SpA
Year: around 1995
The hydraulic power unit is constituted by a 15 kW constant speed electric motor that can drive 4 different interchangeable pumps: radial piston, external gear, balanced rotor vane and unbalanced rotor variable displacement pump with pressure compensator. The unit can supply flow at constant pressure or the flow rate can be imposed by a Danfoss PVG32 load sensing directional control valve. If the directional valve is excluded, a constant flow rate at higher pressure can be delivered.
Technical data:
- As variable flow unit: 0-40 L/min at max 100 bar
- As constant pressure unit: max 50 L/min at max 80 bar
- As constant flow unit: about 20 L/min at max 300 bar
- Oil temperature range: 30-50 °C
