Rexroth A7V Series Heavy-Duty Bent Axis Variable Piston Pumps

Product Overview: The Rexroth A7V series is one of the most classic and durable bent-axis variable displacement pumps in hydraulic history. Specifically engineered for open-circuit high-pressure systems, this series is world-renowned for its exceptional reliability and extreme power density. It covers a complete displacement spectrum from 58cc (A7V58) up to the massive 500cc (A7V500). Featured models such as the A7V107LV, A7V250LRD/63R-VPB-01, and A7V500LV5.0 deliver unmatched performance. With its unique bent-axis rotating group design, the A7V delivers robust power at a rated pressure of 350 Bar, making it the primary “Power Heart” for heavy-duty presses, mining hoists, marine deck machinery, and large-scale industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

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

• Heavy-Duty Control Modalities: Offers diverse options including LV (Constant Power Control) and LRD (Power Control with Pressure Cut-off), ensuring precise power distribution and preventing engine or motor overload.

• Extreme Environment Durability: Built with high-strength cast-iron housings and reinforced bent-axis rotating groups, maintaining peak performance under high temperatures, dust, and continuous high-pressure vibration.

• Optimized Series 63 Engineering: The Series 63 platform refines internal fluid paths and bearing structures, enhancing mechanical efficiency while reducing the installation footprint for easier integration.

• High Maintainability: As an industry-standard model, its rotating components (pistons, cylinder blocks, valve plates) are highly interchangeable, greatly simplifying maintenance and overhaul procedures.
