Rexroth A2F Series High-Pressure Bent Axis Fixed Piston Pumps

Product Overview: The Rexroth A2F series is the recognized “Gold Standard” for fixed displacement pumps in the hydraulic industry. Utilizing an advanced bent-axis architecture, this series is specifically engineered for extreme pressure demands in open-circuit systems. The range features core displacements from the light-duty 23cc (A2F23) to the heavy-duty mainstays of 45cc (A2F45) and 55cc (A2F55). Featured models like the A2F45R2P3, A2F55R2P3, and A2F23R3P4 deliver unmatched performance. With the ultra-high power density of its 40° bent-axis group, the A2F series functions exceptionally as both a high-pressure pump and a fixed motor, widely utilized in crane hoisting, excavator auxiliary drives, injection molding machines, and industrial power units.

Key Technical Advantages:

• Superior Bent-Axis Mechanical Efficiency: The unique 40° bent-axis design allows for larger piston strokes, delivering massive pressure and flow within a compact frame with industry-leading volumetric efficiency.

• Dual-Function Versatility: The A2F operates seamlessly as either a pump or a motor, providing flexibility that makes it an ideal component for complex hydraulic circuits.

• High Pressure Durability: Rated for continuous operation at 350 Bar (5100 PSI) with peak capabilities up to 400 Bar, easily handling the instantaneous shock loads of heavy machinery.

• Excellent Self-Priming Capability: The specially designed spherical valve plate ensures superior suction efficiency even at high rotational speeds, significantly reducing cavitation risks.

• Rugged Construction: Built with high-strength cast housings and reinforced bearing groups, optimized for ultra-long service life in harsh outdoor job sites and high-temperature industrial environments.
