Rexroth A7V Series High-Pressure Axial Piston Variable Pump

Product Overview: The Rexroth A7V series is a high-performance bent-axis axial piston variable pump specifically engineered for Open Circuit drives. This series is widely utilized in heavy-duty excavators, forging machinery, crane hydraulic systems, and large-scale industrial power units. Renowned for its compact bent-axis design and exceptional power-to-weight ratio, the A7V range—from the power-controlled A7V250LV to the electronically modulated A7V160EL—delivers consistent, high-pressure power even in the harshest operating environments.

Key Technical Advantages:

• Superior Bent-Axis Performance: Compared to swashplate pumps, the A7V bent-axis design offers better self-priming capabilities and a longer service life. Models like the A7V160LV1RPF00 maintain peak volumetric efficiency during high-pressure cycles.

• Versatile Variable Control Logic: Supports a wide array of control methods. LV (Constant Power Control) automatically modulates displacement based on system pressure to prevent prime mover overload, while EL (Electronic Proportional Control) allows for seamless integration with modern PLC systems for ultra-precise maneuvers.

• Reinforced for Extreme Pressure: Engineered for rated operating pressures up to 350 Bar (35 MPa), with peaks reaching 400 Bar. Reinforced rotating components and precision-ground port plates ensure reliability in high-displacement applications like the A7V250LV5.1RPFM0.

• Flexible Mounting & Compatibility: Available in specific configurations such as the A7V250LV5.1RPFHO, compliant with standard SAE or ISO interface specifications to ensure a seamless “plug-and-play” replacement for existing heavy machinery and industrial equipment.
