Compact hydraulic power packs are a type of hydraulic power pack. They are
characterised by a highly compact design, since the motor shaft of the electric drive
also acts as the pump shaft. Compact hydraulic power packs are designed to supply
hydraulic circuits with hydraulic uid.
The mini hydraulic power packs of type HR offer reversible direction of ow, achieved
by reversing the direction of rotation of the motor. No directional valve is required.
The motor is protected from overloads by a built-in temperature switch.
