Rexroth A2FO Series Pump | A2FO125, A2FO160, A2FO180 | 400 Bar High Pressure Bent Axis Pump

Rexroth A2FO Series (Series 61) High-Pressure Bent Axis Fixed Pump

Product Overview: The Rexroth A2FO series is the globally recognized “long-life power source” for open-circuit industrial and mobile hydraulic systems. As a staple of the Series 61, it highlights core high-displacement specifications: 125cc (A2FO125), 160cc (A2FO160), and 180cc (A2FO180). Utilizing a unique 40° Bent Axis rotating group, the A2FO pump offers superior self-priming characteristics and higher mechanical efficiency compared to traditional swashplate pumps. Rated for continuous operation at 400 Bar, it provides exceptionally reliable and consistent flow for rotary drilling rigs, concrete pumps, cranes, and heavy-duty industrial presses.

Key Technical Advantages:

• Superior Bent Axis Performance: The 40° bent axis design provides stronger resistance to contamination and exceptional self-priming speeds, ensuring stable fluid charging and preventing cavitation even under high loads.

• High-Pressure Reliability: Rated for an operating pressure of 400 Bar (40 MPa) with peak cycles reaching 450 Bar. Reinforced rotating groups and bearings ensure an extended service life in harsh industrial environments.

• Streamlined Fixed Displacement Efficiency: The fixed displacement structure eliminates complex control variables, resulting in extremely smooth operation and industry-leading volumetric and mechanical efficiency.

• Robust Shaft & Sealing Configurations:

  • VBB05 (A2FO125/180): Equipped with FKM (Viton) seals and heavy-duty industrial shaft ends, offering excellent temperature resistance and torque capacity.

  • VPB05 (A2FO160): Features a shaft form optimized for high-frequency power coupling, ensuring perfect alignment with electric motors or gearbox PTOs.

• Maximum Power Density: The compact housing design delivers high flow output while minimizing installation space requirements and overall system weight.
