Rexroth A7VO500 Series 63 Heavy-Duty Bent Axis Variable Piston Pumps

Product Overview: The Rexroth A7VO series is the world’s premier bent-axis variable displacement pump designed for heavy-duty open-circuit systems. As the flagship of the series, the A7VO500 is engineered for ultra-high power requirements in extreme operating conditions. Featured models include the A7VO500EP2D/63R (Material No.: R902417295) with electronic proportional control and the A7VO500LRD with power control. Utilizing a unique bent-axis rotating group, the A7VO500 delivers a massive 500cc displacement while maintaining superior self-priming speeds and reliability compared to traditional swashplate pumps. It is the core power source for large mining excavators, TBM main drives, offshore winches, and massive industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

• Ultimate Bent Axis Efficiency: The specialized bent-axis architecture allows for larger piston swing angles, achieving higher volumetric and mechanical efficiency within a rugged frame.

• Superior Self-Priming & Speed: The optimized spherical valve plate design allows the A7VO500 to maintain exceptional suction efficiency at high speeds without an auxiliary pump, significantly minimizing cavitation risks.

• Intelligent Control Modalities (EP2D / LRD): EP2D offers high-precision electric proportional displacement regulation with pressure cut-off; LRD features constant power control with pressure compensation to protect the drive motor from overload.

• Series 63 Industrial Engineering: Equipped with reinforced bearing groups and high-strength ductile iron housings, optimized for S1 continuous duty even under a constant 350 Bar operating pressure.

• Extreme Environment Durability: The bent-axis design offers higher tolerance to particulate contamination compared to swashplate pumps, greatly reducing maintenance frequency in mining and dredging applications.
