As the works representative of Concentric, Otto Hydraulics offers a hydraulic unit in this product range with three-phase motors on a modular basis. This compact hydraulic unit primarily designed for industrial applications is available in a great number of variants and can also be equipped with valve linking systems size Cetop 2 + 3.

Due to its compact design it is particularly suited for restricted installation spaces, such as in lifting tables, tool machines or secondary functions of a larger system. With the installation of a d.c. motor it can also be used in mobile hydraulic applications.

To help support your design we naturally have 3D CAD files of the hydraulic units of this series.
