Rexroth A7V Series Pump | A7V58DR, A7VO55LR, A7V225 | Bent Axis Piston Pump

Rexroth A7V & A7VO Series High-Pressure Bent Axis Variable Pump

Product Overview: The Rexroth A7V and A7VO series represent the pinnacle of high-performance bent-axis design in hydraulic transmissions. Compared to traditional swashplate pumps, the bent-axis architecture offers superior self-priming capabilities and higher mechanical efficiency. Featured models like the A7V58DR (Pressure Control), A7VO55LR6.0R-PPB01 (Power Control), and the heavy-duty A7V225.L.V.2.0.R.Z.F.00 are extensively used in heavy-duty cranes, excavator swings, steel mill power units, and various open-circuit industrial machinery.

Key Technical Advantages:

• High-Efficiency Bent Axis Design: The unique bent-axis geometry allows for larger swivel angles, delivering higher power density and excellent suction performance, ideal for high-speed and high-pressure operations.

• Precision Control Mechanisms:

  • DR (Pressure Control): Automatically maintains system pressure and reduces displacement upon reaching the setpoint for efficient constant-pressure operation.

  • LR (Power Control): Modulates flow based on system load, ensuring the prime mover (motor or engine) stays within its optimal power range.

• Ultra-High Operating Pressure: Rated for up to 350 Bar (5000 PSI) continuous operation, with peak capability reaching 400 Bar.

• Exceptional Service Life: Robust rotating groups and heavy-duty bearing designs ensure long-term stability in harsh environments like mining and ports.

• 100% Industrial OEM Compatibility: Manufactured to strict Rexroth Series 2.0 and 6.0 standards, offering diverse shaft and flange configurations for seamless “drop-in” replacement.
