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.

Why Choose EO2 Control?
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
Typical Applications
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

Frequently Asked Questions
Q1: Does EO2 control replace the need for a flow control valve in the circuit?
A1: It allows you to set pump flow electronically, reducing dependence on separate flow control valves for basic regulation. However, precision motion or pressure-compensated flow to individual actuators may still benefit from secondary valving.
Q2: What external electronics are needed for EO2?
A2: EO2 requires a compatible proportional amplifier (often Rexroth VT-series or PLC-integrated analog output card) to supply the command signal and monitor solenoid current. Some versions include onboard electronics — confirm with your supplier.
Q3: Can EO2 pumps be used in closed-loop (hydrostatic) drives?
A3: No. A4VSO pumps are open-circuit only. For closed-loop travel/propulsion drives, refer to the A4VG or A4VM series.
