DV Hydraulics developed and delivered a custom-built digital hydraulic pump in a closed circuit 250cc configuration, designed specifically for an application where no standard market solution was available.

This pump was engineered for exceptional precision, fast response, and fully digital control, tailored to the requirements of a complex regulation system where conventional pumps fell short.

The pump configuration includes the following specifications:

• Closed circuit 250cc pump

• Nominal operating pressure: 350 Bar – Maximum speed: 2200 rpm

• Built-in digital absolute encoder for precise swash plate angle measurement

  • Accuracy: 100 arcsec – Resolution: 0.0007°

• Fully integrated ATOS DLHZO servo-proportional valve with built-in electronics and axis control to drive the pump

• Direct Profinet communication between encoder and valve – no intermediate modules required

• Pressure sensors with 0.1% FS accuracy and refresh rate >1 kHz

Thanks to the direct encoder coupling mounted on the pump's drive shaft, all mechanical tolerances are negligible, resulting in highly stable and precise control.

The pump offers the following advantages:

• Fully digitally controlled via Profinet – seamless PLC integration

• Faster step response – up to 50% quicker than standard market pumps

• ±0.1% control accuracy – for extremely precise pressure, position or speed regulation

• Plug & play as a ready-to-use unit – no complex tuning required

• Also available as a retrofit solution for existing systems

• Multiple units have already been successfully installed and operating flawlessly for years

This pump setup is ideal for industrial applications requiring high-precision in pressure, position, or speed control.

Think of industrial automation, test benches, or high-accuracy actuators where standard hydraulic pumps fall short.
