A4VSO180EO2/30L-PPB13N00 Variable Displacement Piston Pump
The Rexroth A4VSO180EO2/30L-PPB13N00 is a genuine German-produced open-circuit axial piston variable pump from the proven A4VSO series. It features EO2 electro-proportional displacement control, allowing pump flow to be set remotely via an analog electrical signal (±10 V or 4-20 mA) from a PLC or CNC controller.
With a displacement of 180 cm³/r and PPB13 SAE flange & port configuration (compact smaller SAE porting vs. PPB25), this model is ideal for space-limited hydraulic power units and automated machinery requiring precise, programmable flow without manual adjustment. It is rated for 350 bar continuous / 400 bar peak operation.

EO2 Electro-Proportional Control - Key Advantage
Unlike pressure-compensated (DR) or pilot-controlled (DFR) pumps, EO2 enables electric flow command:
- Pump displacement — and therefore flow — follows a linear analog input signal
- Enables fully automated, software-controlled hydraulic systems
- Eliminates manual flow-setting valves in many applications
- Fast-response proportional solenoid for dynamic processes
- Compatible with external pressure limiting or cut-off for system safety
Typical Applications
- Automated production lines with PLC-controlled hydraulic cycles
- Hydraulic test benches & calibration rigs requiring programmable flow
- Material testing machines (tensile/compression) with servo-hydraulic actuation
- Packaging & converting machinery with variable flow demand
- R&D laboratory hydraulic systems and university engineering labs
- Retrofit projects upgrading manual/displacement-controlled pumps to electronic control

Frequently Asked Questions
Q1: What is the difference between PPB13 and PPB25 on A4VSO180 pumps?
A1: Both use SAE flanges and ports. PPB13 has the smaller SAE port size for compact manifold integration; PPB25 uses larger SAE ports for higher-flow piping. Pump displacement, pressure and flow performance are identical — select based on your manifold/hose standard.
Q2: Does EO2 control require additional electronic components?
A2: 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. Some versions include onboard electronics — verify with your supplier.
Q3: Can this pump be used in a closed hydrostatic transmission?
A3: No. The A4VSO series is for open circuit (open loop) only. For closed-loop track or wheel motor drives, use the A4VG or A4VM series.
