Product Description
A4VSO125EO2/30L-PPB13N00 Coal Mine Steel Plant Piston Pump
Product Introduction
The Rexroth A4VSO125EO2/30L-PPB13N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, featuring EO2 electro-proportional displacement control. With a displacement of 125 cm³/r and PPB13 SAE compact flange & ports, this pump allows flow to be set precisely via an analog electrical signal (±10 V DC or 4-20 mA) from a plant DCS, PLC, or VFD-compatible controller.
In steel plant and coal mine surface installations, the A4VSO125EO2 is typically deployed in auxiliary hydraulic circuits such as:
- Cooling fan drive pumps on rolling mill lubrication skids
- Conveyor belt tensioning systems in coal preparation plants
- Filter press hydraulics and emulsion station auxiliary pumps
- Furnace door/cover slow-close hydraulic actuators
The compact PPB13 porting integrates neatly into manifold-mounted plant skids, while the EO2 control supports automated, variable-flow operation — reducing energy consumption during standby or partial-load conditions. Rated 350 bar continuous / 400 bar peak.

EO2 Electronic Flow Control - Plant Automation Benefit
Unlike DR/DFR which rely on hydraulic pilot pressure, EO2 is commanded purely by electrical signal:
- Flow proportional to analog input — no hydraulic pilot source needed
- Enables remote setpoint from plant control room / PLC / DCS
- Pump can be ramped up/down gradually to reduce system shock
- During idle or hold periods, flow can be reduced to minimum — cutting heat and power draw
- Compatible with frequency-controlled motor + variable pump strategies for maximum energy saving
➡ Particularly valued in modernized steel mill and mine plant retrofits moving from fixed-displacement or manual pumps to digitally controlled hydraulics.
Typical Applications
- Steel & Metals: rolling mill cooling fan pumps, caster spray bar hydraulic supply, furnace cover/door slow-close actuators, slab handling auxiliary circuits
- Coal & Mining (Surface): coal prep plant conveyor tensioning, filter press pumps, belt scale hydraulic drives, mine winder lubrication skid auxiliaries
- Power Plant: soot blower hydraulic drive, turbine lube oil top-up pump
- Industrial Process: emulsion station auxiliary pump, mixer variable-flow supply
- Retrofit Projects: upgrading manual or fixed-displacement pumps to PLC-controlled variable flow

Frequently Asked Questions
Q1: What external electronics are needed to run the EO2 pump?
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: Can EO2 be used in hazardous (mine) areas?
A2: The pump itself is hydraulic; the solenoid and amplifier must be selected for the required Ex certification (e.g. Ex d, Ex e) if installed in a classified zone. Confirm with your project engineer and local code.
Q3: What is the difference between PPB13 and PPB25?
A3: Both are SAE flanges/ports. PPB13 is the compact SAE port size, preferred for manifold-mounted plant skids; PPB25 uses larger SAE ports for high-flow piped systems. Pump displacement and pressure performance are identical.
Q4: Is the A4VSO series suitable for closed-circuit track/wheel drives?
A4: No. A4VSO is for open circuit (open loop) only. For closed-loop travel drives, use the A4VG or A4VM series.
