A4VSO71EO2/30L-PPB13N00 Piston Pump for Mining Loader Hydraulic System – Rexroth – Germany
Product Overview
The A4VSO71EO2/30L-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 heavy-duty mobile and industrial equipment—including mining loader 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 EO2 control is an electro-proportional displacement control: an external analog signal (typically ±10 V or 4-20 mA via a proportional amplifier with LVDT feedback) sets the swash plate angle and therefore the pump flow, which allows PLC- or CAN-based controllers on modern mining loaders to schedule lift, steer, and brake flows precisely. Rated at 350 bar nominal / 400 bar peak, it is built for continuous duty under shock loads, dust, and wide temperature swings typical of underground and surface mining.

Frequently Asked Questions
Q: Is the A4VSO71EO2/30L-PPB13N00 made in Germany?
A: Yes. This configuration is produced in Rexroth Germany facilities. We provide original label photos, test report, and COO on request.
Q: What does EO2 control require to work on a mining loader?
A: EO2 needs an external proportional amplifier receiving ±10 V or 4-20 mA command plus a pilot pressure source (higher than EO1). The pump includes LVDT feedback; system relief valve is still mandatory for pressure limiting.
Q: Can EO2 replace a DR or DFR pump mechanically on the same loader?
A: If displacement (71), rotation (L), shaft (P), flange (B), and ports (13) match, the pump mounts identically. Control behavior changes from pressure/flow-pilot to electric-signal flow command—loader software/PLC must be updated for EO2.
Q: Does PPB13N00 mean SAE or metric ports?
A: Code 13 = SAE B (pressure) and SAE S (suction) flanges on side, 90° offset, with metric mounting bolts. Adaptors to ORFS/NPT are common but not built-in.
Q: Lead time?
A: Stock units 1-3 working days; non-stock 1-2 weeks depending on quantity.
