Rexroth A7VO160 Series Axial Piston Variable Displacement Pumps

Product Overview: The Rexroth A7VO160 is a premier axial piston variable displacement pump designed for open-circuit hydraulic systems, featuring the advanced Bent-Axis architecture. Renowned for its exceptional volumetric efficiency and high power density, the A7VO160 is the powerhouse for heavy-duty machinery. This featured selection includes precision control configurations: the multi-functional A7VO160LRDH1/63R-NPB01 (integrating power, pressure, and hydraulic stroke control), the pressure-regulated A7VO160DR/63R-NZB01-S, and the classic A7VO160LR/63R-VZB01. With its 160cc displacement, this pump is the ideal choice for large excavators, mobile cranes, rotary drilling rigs, and industrial press power units.

Key Technical Advantages:

• Bent-Axis Technology: The bent-axis design allows for a larger swivel angle compared to swash-plate pumps, resulting in superior self-priming capabilities and extended bearing life under high loads.

• Versatile Control Strategies:

  • LRDH1: Combines Power Control (LR), Pressure Control (D), and Hydraulic Stroke Control (H1) for ultimate power optimization and precise flow distribution.

  • DR: Pressure Control logic that automatically de-strokes the pump when the set pressure is reached, ensuring system safety and energy savings.

  • LR: Constant Power Control, matching the pump’s power absorption to the engine’s output to prevent stalling.

• High-Pressure Resilience: Rated for continuous operation at 350 Bar (5000 PSI) with peak capabilities reaching 400 Bar (5800 PSI) for extreme duty cycles.

• Series 63 Optimized Design: The Series 63 iteration features an upgraded rotary group and valve plate, significantly reducing operational noise and enhancing efficiency at high temperatures.

• Target Applications: Heavy construction machinery, mining equipment, offshore winches, industrial extrusion presses, and injection molding main drives.
