A4VSO180EO1/30L-PPB25N00 Rexroth Industrial Piston Pump Made in Germany
Product Introduction
The Rexroth A4VSO180EO1/30L-PPB25N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump featuring EO1 electro-proportional displacement control. With a displacement of 180 cm³/r and PPB25 SAE flange & ports, pump flow is set remotely via an electrical control signal, allowing seamless integration into PLC- or CNC-controlled hydraulic systems.
Rated for 350 bar continuous / 400 bar peak, the EO1-controlled A4VSO180 is commonly used in automated machinery, hydraulic test rigs, and process plant power units where flow must be adjustable on-the-fly by an electronic command rather than manual or hydraulic pilot pressure.

The EO1 function enables direct electrical control of pump displacement:
Flow output is proportional to an external analog command signal (typically ±10 V DC or 4-20 mA)
No hydraulic pilot pressure required for flow setting -- simplifies hydraulic circuit design
Allows remote, programmable flow changes via PLC, HMI or motion controller
Can be combined with external pressure relief or cut-off valve for system protection
Suitable for modernizing fixed-displacement or manually adjusted systems to digitally controlled hydraulics
EO1 is an earlier/alternative electro-proportional code to EO2 -- both achieve electric flow command; exact solenoid type, stroke limiter and amplifier compatibility should be confirmed per project.
Typical Applications
Automated special-purpose machines with programmable hydraulic cycles
Hydraulic test benches & calibration stands needing remote flow setpoint
Servo-hydraulic material testing systems
Packaging, converting and printing machinery with variable flow demand
Process industry hydraulic skids integrated with plant automation
R&D laboratories and university hydraulic training rigs

Frequently Asked Questions
Q1: What external electronics are needed to operate the EO1 control?
A1: A proportional amplifier (such as Rexroth VT-series) or a PLC analog output card is required to supply the command signal and monitor solenoid current. Verify whether your pump version includes onboard electronics or requires an external amplifier.
Q2: How is EO1 different from DFR or DR control?
A2: DR is hydraulic constant-pressure only; DFR uses hydraulic pilot pressure to set flow & pressure. EO1 uses an electrical signal to directly command displacement -- giving you software-controlled flow independent of hydraulic pilot pressure.
Q3: Can the A4VSO180 be used in a closed hydrostatic transmission?
A3: No. The A4VSO series is designed exclusively for open circuit (open loop) systems. For closed-loop travel/wheel drives, use the A4VG or A4VM series.
