Based on its award winning Digital Displacement® technology, Artemis Intelligent Power has started the process of installing Digital Displacement® pumps in a 16T excavator

Today’s excavators have reached a mature level of technology using variable-stroke hydraulic pumps. They are rugged, dependable machines which operate in tough conditions. However, at the heart of all modern excavators lie a number of problems: the mechanical pumps have substantial energy losses, the valve systems waste fluid energy by throttling flow to control multiple axes and energy which could be recovered is instead converted into heat.

With a peak efficiency of 93 – 97% across a wide range of operating points, Digital Displacement® Technology is a revolution in efficiency and control of variable displacement hydraulic machines.

Key to the hydraulic excavator’s success is fine control and the ability to convert maximum power from the engine into multiple linear motions. Before and after comparisons based on standard trenching and loading cycles are to be evaluated to provide data on energy savings and controllability.

Artemis, a member of the British Fluid Power Association will use the mule excavator to demonstrate the fuel economy and productivity benefits of Digital Displacement® technology to major industry OEMs in the off-highway sector.
