The A4VSO71EO1/30L-PPB13N00 is an axial piston variable displacement pump from the Rexroth A4VSO Series 30, manufactured in Germany, and engineered for open-circuit hydrostatic drives in both industrial hydraulic power units and mining equipment hydraulic systems.
It uses a swash plate design where output flow is proportional to drive speed and displacement, with stepless adjustment via swash plate angle. The EO1 control is an electro-proportional displacement control: an external analog signal (typically ±10 V, 0-10 V, or 4-20 mA via an external proportional amplifier) sets the swash plate angle and therefore the pump flow, enabling PLC- or DCS-based systems to command flow precisely without hydraulic pilot pressure.
Rated at 350 bar nominal / 400 bar peak, it is built for continuous 24/7 duty under shock loads, dust, and wide temperature swings typical of steel plants, mining loaders, and underground conveyors.

Mining loaders, LHD units, crushers, conveyor tensioning systems require PLC-commanded variable flow for boom, bucket, steer, and brake circuits → EO1 lets the machine controller schedule flow electrically.
Steel plant rolling stands, ceramic presses, forging presses benefit from precise electric flow ramping to reduce pressure spikes and heat generation.
Left-hand rotation (L) matches specific gearbox inputs on popular industrial drivelines.
German-origin reliability reduces unplanned downtime in continuous-process and underground environments.
