Rexroth A10VSO71 & A10VSO100 & A10VSO140 Pump | DFR1 Load Sensing | DR Pressure Control

Rexroth A10VSO Series 31 Large Displacement Variable Piston Pumps

Product Overview: The Rexroth A10VSO series is the global standard in heavy-duty industrial hydraulic drives. This selection features the high-power displacement range: 71cc (A10VSO71), 100cc (A10VSO100), and the maximum 140cc (A10VSO140). These pumps provide precision control options, including DFR/DFR1 (Load Sensing) for energy-efficient speed regulation and DR (Pressure Control) for high-efficiency pressure holding. With its robust swashplate architecture, the A10VSO series maintains superior volumetric efficiency across intense industrial cycles, serving as the premier power source for heavy stamping presses, metallurgical HPUs, injection molding drives, and large-scale machine tool units.

Key Technical Advantages:

• Heavy-Duty Industrial Performance: Engineered for continuous high-pressure operations, rated at 280 Bar (4060 PSI) with peak capabilities up to 350 Bar (5100 PSI) for ultimate reliability.

• Precise Flow & Pressure Regulation: Equipped with DFR1 (Load Sensing) regulators, the pump reacts instantly to actuator demand, matching flow precisely to minimize overflow heat loss and energy costs.

• Low-Noise Swashplate Design: Optimized 9-piston rotating groups suppress pressure ripples, ensuring exceptional low-noise performance even at full speed in indoor factory environments.

• Superior Power Density: The compact housing integrates high-performance compensators and supports through-drive options, allowing users to easily mount tandem auxiliary pumps for complex systems.

• Extended Service Life & Low Maintenance: Critical internal friction pairs undergo specialized hardening and precision grinding, significantly extending overhaul intervals and reducing machine downtime.
