Hawe HS 120 Hydraulic Power Pack


The Hawe HS 120 is a servo hydraulic power pack. The system consists of a constant pump and a directly flange-mounted servomotor. Depending on the application of the HS, a number of different motor/frequency converter combinations and pump delivery flow rates are available.

This servo hydraulic power pack allows the set up of reverse operation without any additional valve technology. Similarly, different variants of integrated check valve can be used. The tank also features a level/temperature switch.

The HS 120 contains a powerful servo electric drive. Its ‘power-on-demand’ results in impressively high energy efficiency and allows it to be used without additional cooling, keeping the system compact. Low required oil fill volumes allow less oil to be used, hence running costs for replacing hydraulic fluid are cut – this also reduces the environmental impact of running this system. This power pack is a highly dynamic and energy-efficient drive unit.  The compact design of this system and low noise output make it suitable for environments with reduced space or mobile equipment.
