Many of the vehicles and machines we rely on today are based on technologies developed more than a century ago.
Conventional hydraulic pumps – the core technology in many off-road vehicles and industrial machines– is controlled by changing the stroke of the piston with an analogue ‘swash plate’ mechanism, first patented in 1893.
This mechanism has a number of disadvantages – it is not easily controlled and there are many system energy losses, for example through idling, leakage and friction.
Introducing a fundamental innovation in hydraulic technology: Digital Displacement® Pump
Our Digital Displacement® technology is a fundamental innovation. It utilises a radial piston machine which enables cylinders in real-time, using ultra-fast mechatronic valves controlled by an embedded computer.
These intelligent, digital controls mean a Digital Displacement machine is highly controllable and extremely efficient – individual cylinders are only called into action as and when required. The net result is:
- dramatically lower energy losses (typically less than a third of swashplate machines);
- dramatically faster response (typically ten times faster);
- reduction of annoying, high-frequency noise.
By replacing a mechanical device with one which is controlled by computer, new possibilities of system control, diagnostics and automation are enabled.
