Most hydraulic pumps today have the same basic control mechanism that was first patented in 1893. The variable-angle swash plate pump has been a reliable way to transmit fluid power for over 120 years.
Efforts have been made to digitize the mechanism with feedback and electronic control, but the underlying principle has limited benefits.
The Digital Displacement® industrial offering is a natively digital hydraulic innovation. It utilizes a radial piston machine which enables cylinders in real-time, using ultra-fast mechatronic valves.
These intelligent, digital controls mean a digitally-enabled machine is highly controllable and extremely efficient. The net result is:
- Radically lower energy losses (typically less than a third of swashplate machines);
- Dramatically faster response (typically ten times faster);
- Reduction of annoying, high-frequency noise
Individual cylinders are only called into action when required to meet the load demanded, resulting in a pump with efficiency over 90 percent.
The control of individual cylinders allows a single pump to have multiple independently-controllable services providing system innovators a platform to invent new architectures to unlock the capabilities of digital hydraulics.
By replacing a mechanical or hydraulic device with one which is electronically and digitally controlled, new possibilities of flow metering, response, system control, diagnostics and automation are now possible. The pump is able to create real-time data for live streaming via telematics.
