A4VSO180EO1/30L-PPB13N00 Loader excavator motor piston pump German Rexroth

The Rexroth A4VSO180EO1/30L-PPB13N00 is a genuine German-manufactured open-circuit axial piston variable pump from the A4VSO series, featuring EO1 electro-proportional displacement control. With a displacement of 180 cm³/r and PPB13 SAE compact porting, this pump is designed for applications where flow must be set remotely via an electrical control signal—either from a PLC, CAN bus interface, or dedicated proportional amplifier.

While primarily an industrial pump, the A4VSO180EO1 is also found in loader/excavator auxiliary hydraulic circuits, such as fan drive systems, cooling pumps, or supplementary tool hydraulics on heavy mobile equipment. Its compact PPB13 porting makes it easier to integrate into space-constrained machine frames.

Rated for 350 bar continuous / 400 bar peak, the pump delivers reliable high-pressure performance in demanding working conditions.

The EO1 function provides direct electrical command of pump displacement:

• Flow output is linearly proportional to an external analog signal (±10 V DC or 4-20 mA typical)
• No hydraulic pilot pressure required for flow setting—simplifies circuit architecture
• Enables remote, programmable flow changes via operator cab controls, PLC, or machine controller
• Suitable for integrating into CAN-based or analog-controlled mobile hydraulic systems
• Can be paired with external pressure limiting valve for system overload protection
