A4VSO125EO1/30L-PPB25N00 Rexroth German Piston Pump
Product Introduction
The Rexroth A4VSO125EO1/30L-PPB25N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, equipped with EO1 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 DC or 4-20 mA) from a PLC, DCS, or proportional amplifier.
The EO1 control provides direct electronic command of pump displacement—eliminating the need for hydraulic pilot pressure to set flow. This makes the A4VSO125EO1 particularly suitable for industrial high-pressure hydraulic power units and mining equipment auxiliary circuits (conveyor tensioning, cooling fan drives, filter press feeds, lubriion skids) where automated, repeatable flow control is required. Rated for 350 bar continuous / 400 bar peak, with PPB25 SAE porting for minimized pressure drop in higher-flow plumbing.

EO1 Electro-Proportional Control - Key Benefits
Pump displacement—and therefore flow—is linearly proportional to an external analog command signal
No hydraulic pilot pressure required for flow setting → simplifies hydraulic circuit design
Enables remote, programmable flow changes via plant PLC, HMI, or DCS
Allows pump to be ramped up/down electrically, reducing system shock on start/stop
Can be paired with external pressure relief or cut-off valve for system protection
Suitable for modernizing fixed-displacement or manually adjusted systems to digitally controlled hydraulics
Note: EO1 and EO2 are both electro-proportional; differences lie in solenoid type/stroke limiter and amplifier compatibility—confirm with your Rexroth distributor when selecting spare parts or electronics.
Typical Appliions
Mining & Mineral Processing: conveyor belt tensioning, cooling fan pump drives, filter press hydraulics, lube oil skids, thickener rake drives
Process Industry: mixer variable-flow supply, packaging machine hydraulics, test bench programmable flow
Material Handling: crane auxiliary circuits, outrigger/stabilizer pumps
Retrofit Projects: upgrading manual or fixed-displacement pumps to PLC-controlled variable flow

Frequently Asked Questions
Q1: Does EO1 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 the command signal and monitor solenoid current. Check whether your pump version includes onboard electronics.
Q2: Can EO1 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 motor drives, use the A4VG or A4VM series.
