A4VSO180EO2/30L-PPB25N00 Industrial axial piston pump Rexroth German hydraulic pump
The Rexroth A4VSO180EO2/30L-PPB25N00 is a genuine German-manufactured open-circuit axial piston variable pump from the A4VSO series, equipped with EO2 electro-proportional displacement control. With a displacement of 180 cm³/r, this pump allows remote, signal-based flow adjustment via a 4-20 mA or ±10 V command signal—making it ideal for modern PLC- or CNC-controlled hydraulic systems where precise, repeatable flow regulation is required.
Rated for 350 bar continuous / 400 bar peak, and fitted with PPB25 SAE flange and ports, the A4VSO180EO2 is commonly integrated into automated test benches, servo-hydraulic systems, specialized production machinery, and process plant hydraulic power units.

Unlike DR (pressure-only) or DFR (pilot-pressure flow), EO2 gives you direct electronic command over pump displacement:
- Flow is set by an analog electrical signal (±10 V / 4-20 mA) — no mechanical or hydraulic pilot required
- Enables fully automated, programmable flow profiles via PLC or motion controller
- Supports integration with Industry 4.0 / digital hydraulic concepts
- Fast response proportional solenoid for dynamic load changes
- Can be combined with pressure cut-off or pressure limiting functions externally
- Automated hydraulic test rigs & calibration benches
- CNC/special-purpose production machines with flow-programmed cycles
- Servo-hydraulic material testing machines (MTS-style setups)
- Process industry hydraulic skids requiring remote flow setpoint
- Research & development laboratories and university hydraulic labs
- Upgrading legacy fixed-displacement or manually controlled pumps to electronically governed systems
