Product Description
A4VSO125EO2/30L-PPB25N00 German Rexroth Variable Piston Pump Industrial Mining
Product Introduction
The Rexroth A4VSO125EO2/30L-PPB25N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, equipped with EO2 electro-proportional displacement control. With a displacement of 125 cm³/r and PPB25 SAE flange & ports, pump flow is set remotely via an analog electrical signal (±10 V or 4-20 mA) from a PLC or machine controller.
This compact-size A4VSO125 is widely used in industrial hydraulic power units and mining equipment auxiliary circuits — such as conveyor tensioning systems, cooling fan drives, filter press hydraulics, and lubrication skids — where precise, programmable flow control is required without hydraulic pilot pressure. Rated for 350 bar continuous / 400 bar peak.

EO2 Electro-Proportional Control - Key Advantage
- Pump displacement — and therefore flow — follows a linear analog input signal
- Enables fully automated, software-controlled hydraulic systems (PLC/CNC/Motion Controller)
- Eliminates manual flow-setting valves or hydraulic pilot sources in many applications
- Fast-response proportional solenoid for dynamic load changes
- Can be combined with external pressure limiting or cut-off for system safety
Ideal when your application demands repeatable, remote-controlled flow in a compact pump package.
Typical Applications
- Mining & Quarrying: conveyor belt tensioning, cooling fan pump drives, filter press hydraulics, lube oil skids
- Industrial Plants: hydraulic power units for stamping/pressing auxiliaries, machine tool clamp circuits
- Process Industry: mixer hydraulics, packaging machine flow control, test bench programmable flow
- Material Handling: crane auxiliary circuits, stabilizers, outrigger pumps
- R & D / Lab: electro-hydraulic teaching rigs and calibration benches

Frequently Asked Questions
Q1: Does EO2 control require additional electronic components?
A1: Yes. An external proportional amplifier (e.g. Rexroth VT-series) or a PLC analog output card is required to supply and monitor the command signal to the EO2 solenoid. Confirm whether your version includes onboard electronics.
Q2: Can EO2 replace a flow control valve?
A2: It allows you to set pump flow electronically, reducing dependence on separate flow control valves for basic regulation. Precision motion or pressure-compensated flow to individual actuators may still benefit from secondary valving.
Q3: Is the A4VSO125 suitable for closed-circuit track drives?
A3: No. The A4VSO series is for open circuit (open loop) only. For closed-loop travel/wheel drives, use the A4VG or A4VM series.
Q4: What is the difference between PPB13 and PPB25?
A4: Both are SAE flanges/ports. PPB25 uses larger SAE ports for reduced pressure drop at higher flow; PPB13 is the compact version. Pump performance is identical — select based on your manifold or piping standard.
