Rexroth A10VO Series 31 Load-Sensing Variable Axial Piston Pumps

Product Overview: The Rexroth A10VO series is the most widely utilized variable displacement piston pump in the global mobile hydraulics industry. As the benchmark of the Series 31 platform, it is specifically engineered for open-circuit applications with a superior power-to-weight ratio. The range covers core displacements from the mainstream 28cc (A10VO28) and 45cc (A10VO45) to the high-power 71cc (A10VO71), 100cc (A10VO100), and 140cc (A10VO140). Featured models like the A10VO71DFR1/31R-VSC94K07-S deliver exceptional control. Utilizing advanced DFR1 (Load Sensing + Pressure Control) logic, the pump precisely matches flow to actuator demand, significantly reducing energy consumption and enhancing operational smoothness.

Key Technical Advantages:

• Intelligent DFR1 Load Sensing: Automatically detects load pressure changes and delivers only the required flow and pressure, minimizing relief losses and preventing excessive oil temperatures.

• Rugged Series 31 Architecture: Optimized for the dynamic conditions of mobile machinery, offering excellent suction characteristics and vibration resistance for high volumetric efficiency in harsh environments.

• Compact Through-Drive Capability: Supports 100% power through-drive for tandem mounting of auxiliary pumps, facilitating the design of complex multi-circuit hydraulic systems.

• Whisper-Quiet Operation: The optimized 9-piston design and noise-reduction housing maintain industry-leading low decibel levels, even under high-pressure operations.

• High Interchangeability: Complies with SAE standard flanges and shaft specifications (e.g., VSC94K07), making it the ideal choice for hydraulic pump retrofits in construction and agricultural machinery.
