Pumps using digitally controlled displacement technology make it practical to replace mechanical gearboxes in mobile equipment with hydraulic transmissions, providing fuel savings of up to 20% and productivity increases of nearly 30%. Much of the mobile equipment in use today operates with conventional hydraulic pumps controlled by changing the stroke of pistons with a swash-plate mechanism. Because swashplate position is not easily controlled, energy is lost through volumetric and mechanical inefficiencies. A new technology, the Digital Displacement Pump overcomes these limitations by using multiple radial cylinders that are enabled and disabled in real time with ultra-fast mechatronic valves controlled by an embedded computer.
