1 Overview mini hydraulic power pack type HR 050

Compact hydraulic power packs are a type of hydraulic power pack. They arecharacterised by a highly compact design, since the motor shaft of the electric drivealso acts as the pump shaft. Compact hydraulic power packs are designed to supplyhydraulic circuits with hydraulic uid.

The mini hydraulic power pack type HR 050 is distinguished by its inboard radialpiston pump in the smallest of spaces. The unit is reversed by reversing the directionof rotation of the motor, eliminating the need for a switching valve. The integratedtemperature switch ensures an overload protection for the motor.

■ radial piston pump directly integrated in pump carrier■ round, transparent tank with M8x1filling screw

Features and benets■ intermittent operation■ 12 V DC■ different mounting position■ ingress protection class IP67

Intended applications■ automotive engineering■ sport boats, jet skiing■ agricultural technology, construction machinery, commercial vehicles■ industry■ not applied for use in hazardous places and direct sunlight
