Product Description

Rexroth A7VO Series High-Pressure Bent Axis Variable Piston Pumps

Product Overview: The Rexroth A7VO series is the premier power source for high-performance open-circuit hydraulic systems. Engineered with a unique bent-axis design, this series is renowned for its exceptional power density and high self-priming speeds. The range covers a full displacement spectrum from the compact 28cc (A7VO28) to the massive 1000cc (A7VO1000). Featured models like the A7VO107LR/63R-NPB01 (with power control) and A7VO250DR/63R-VPB01 (with pressure control) deliver precise and robust flow output at a rated pressure of 350 Bar. Its rugged architecture makes it the core component for crawler cranes, rotary drilling rigs, marine deck machinery, and large-scale industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

  • Superior Self-Priming Performance: The bent-axis design allows for higher operating speeds and maintains excellent suction efficiency without an auxiliary pump, minimizing cavitation risk.

  • Extreme High-Pressure Durability: Rated for continuous operation at 350 Bar (5100 PSI) with peak capability up to 400 Bar, ensuring structural integrity under maximum load.

  • Precision Control Modalities: Offers diverse options including LR (Power Control), DR (Pressure Control), and HD (Hydraulic Proportional), optimizing fuel efficiency and protecting the engine.

  • Compact Series 63 Engineering: The optimized Series 63 platform reduces the installation footprint while enhancing bearing life and vibration resistance.

  • Versatile Mounting Compatibility: Strictly adheres to ISO/DIN mounting standards with high-strength splined shafts (NPB/VPB specs), ensuring seamless integration with gearboxes and power take-offs.

Detailed Models & Parameters:

  • Core Series: Rexroth A7VO Series 63 (Bent Axis).

  • Model Keywords: A7VO28, A40, A55, A80, A107, A160, A250, A355, A500, A1000.

  • Full Config Codes: A7VO107LR/63R-NPB01, A7VO250DR/63R-VPB01.

  • Displacements: 28 cm³/rev to 1000 cm³/rev.
