Large Scale Hydraulics


Digital Displacement Technology has enabled the creation of the largest hydraulic machines in the world.  At every scale, the intrinsic efficiency of Digital Displacement Technology allows the boundaries of application of hydraulic machines to be expanded.  This is not least demonstrated by the application of a purely hydraulic drive to wind turbines with a rated power output of 7MW.

Multi-MW Pumps

High Speed, High Torque – HSHT

Digital Displacement opens up new boundaries for hydraulic machines.  The most powerful, single shaft hydraulic motor in the world, designed for the MHI 7MW wind transmission.
