Units & systems
HYDAC power units are the beating heart of every hydraulic system. We combine our decades of expertise in filtration, energy storage and valve technology to create compact or large-scale drive solutions. And our approach goes far beyond standard design: we consider the system as a whole, optimise energy consumption and integrate cutting-edge sensors to make your machine more powerful, quiet and future-proof.

Modularity meets bespoke engineering
Whether you need a space-saving compact power unit for machine tools or a complex large-scale power unit for heavy industry – our modular system enables precise scaling. Using 3D design programs and simulation software, we optimise tank flow characteristics and minimise space requirements. The integration of frequency inverters and variable-speed drives (e.g. DVA) also enables energy savings of up to 70% compared with conventional systems.

Partnership from project planning to aftersales service
For procurement managers and project engineers, ‘HYDAC power units and systems’ means a dramatic reduction in complexity. You receive a validated complete solution including documentation and certifications, all from a single source. Our global service network also provides worldwide support for installation and commissioning. By integrating smart services (condition monitoring), we can monitor the status of your power unit worldwide and, in so doing, optimise operating costs throughout the entire life cycle (TCO).
