Product Description
Rexroth A2FO Series High-Pressure Bent Axis Fixed Piston Pumps
Product Overview: The Rexroth A2FO Series is a fixed displacement axial piston pump specifically engineered for open-circuit hydraulic systems. Featuring the iconic 40° bent-axis design, the A2FO series offers unmatched self-priming characteristics and elite power density. This category features the full range from the compact A2FO12 to the medium-large A2FO90, including precision configurations like A2FO90/61R-PBB05, A2FO23/61R-PZP060, and A2FO32/61L-PAB05. These units are the definitive choice for construction machinery, truck-mounted hydraulics, auxiliary power units (APUs), and industrial hydraulic stations.
Key Technical Advantages:
Elite Self-Priming: Capable of high-speed operation without the need for a charge pump, reducing overall system complexity.
High-Pressure Resilience: Rated for a continuous pressure of 350 Bar with peak capabilities reaching 400 Bar (5800 PSI), ideal for heavy-duty cycle impacts.
Compact Installation: Fixed displacement compact design with versatile mounting flanges and porting options for easy integration.
High Volumetric Efficiency: Precision bent-axis technology minimizes mechanical friction, ensuring an efficiency rate of up to 95%.
Target Applications: Concrete mixers, crane hydraulic pumps, road maintenance machinery, and special vehicle hydraulic systems.
