Rexroth A7V Series High-Pressure Bent Axis Variable Pump

Product Overview: The Rexroth A7V series is a legendary cornerstone of heavy-duty industrial hydraulics. Engineered with the classic Bent Axis variable piston technology, this series covers displacement ranges from the robust 250cc (A7V250) to the ultra-high power 500cc (A7V500). Featured models such as the A7V250LV1 and A7V500DR5.1 are specifically designed for open-circuit systems operating under extreme duty cycles. Utilizing a unique spherical valve plate and bent axis rotating group, the A7V delivers unparalleled volumetric efficiency and mechanical longevity at pressures up to 350-400 Bar, making it the primary choice for large hydraulic extruders, heavy-duty scrap shears, and TBM power stations.

Key Technical Advantages:

• Superior High-Pressure Reliability: The bent axis architecture offers lower lateral forces and a wider displacement range compared to swashplate designs, supporting continuous operation at 350 Bar with peak capabilities of 400 Bar.

• Versatile Precision Controls (LV/DR):

  • LV (Constant Power Control): Automatically modulates displacement based on load pressure, ensuring optimal power utilization and preventing motor overload.

  • DR (Pressure Compensator): Returns the pump to zero displacement once the preset pressure is reached, maintaining constant pressure while maximizing energy efficiency.

• Exceptional Self-Priming & Startup: Optimized rotating group geometry provides excellent suction characteristics even at lower speeds, reducing the need for high boost pressures.

• Reinforced Heavy-Duty Bearing Systems: Engineered to meet the high-intensity requirements of LV5.1 / DR5.1 specifications, drastically extending service intervals.

• 100% Industrial Compatibility: Manufactured to strict SAE or ISO mounting standards (RPF00), ensuring a seamless “plug-and-play” replacement for legacy heavy hydraulic units.
