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.

Model Code Breakdown

A4VSO - Axial piston variable pump, open circuit, swash plate design

71 - Nominal displacement 71 cm³/rev

EO2 - Electro-proportional displacement control, high pilot pressure type (external signal sets flow)

30 - Series 30 construction

L - Left-hand rotation

PPB13N00 - P: NBR+FKM seals; P: parallel key shaft; B: ISO 4-bolt flange; 13: SAE side-offset ports; N00: no through-drive / no aux pump

Key Features
  • Made in Germany - Rexroth German production; original label, test sheet, and COO available on request.
  • EO2 Remote Flow Command - Flow set by ±10 V / 4-20 mA; no mechanical lever or hydraulic pilot needed for basic proportionality; integrates with loader ECU/PLC.
  • Mining-Loader Ready - Short control response time, excellent suction characteristics, low noise, robust roller bearings for shock-load cycles.
  • 350 bar Continuous Duty - Hardened cylinder block, heavy-duty bearings, optimized port geometry for dusty suction conditions.
  • Swash Plate Variable Displacement - Infinitely variable flow, visual swivel angle indicator included.
  • Modular A4VSO Platform - Same mounting envelope as DR/DFR/LR controls for easy retrofit on existing loader power packs.
  • Through-Drive Body (N00 base) - Base variant without tandem shaft; tandem versions exist under other suffixes for combined steering + lift circuits.
Why Used in Mining Loader Hydraulic Systems

Modern mining loaders (LHD - Load-Haul-Dump units, underground scoops, surface wheel loaders) require:

  • Precise electronic flow split between boom, bucket, steering, and brake cooling circuits → EO2 enables ECU to command each pump electronically.
  • High pressure (350 bar) with variable flow to reduce engine throttling and heat generation during idle/hold.
  • Left-hand rotation (L) matched to specific gearbox input orientation on popular loader drivelines.
  • PPB13N00 SAE side ports for straightforward hose routing in tight engine compartments.
  • German-origin reliability for 24/7 underground operation where downtime cost is high.
Other Typical Applications
  • Underground Mining Equipment - LHD loaders, roof bolters, feeder breakers, TBM aux circuits
  • Surface Mining - Wheel loader auxiliary pumps, shovel lubrication hydraulics, crusher power packs
  • Construction & Quarry - Excavator auxiliary circuits, crusher mobile skids, screen vibrator hydraulics
  • Industrial Automation - Test benches, CNC flow-programmed cells, press feeding systems
  • Marine & Ports - Deck machinery power packs with PLC flow scheduling
Quality Assurance & Packaging
  • Origin: Sourced from Rexroth Germany production channels; pre-shipment pressure/flow/leak test performed.
  • Export Packaging: Fumigation-free wooden crate, VCI anti-rust film, corner protectors.
  • Docs: Commercial Invoice, Packing List, Certificate of Origin, factory test report.
  • Warranty: 12 months against manufacturing defects.

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.
