Rexroth A10VSO140 Series 31 Power-Controlled Variable Piston Pumps

Product Overview: The Rexroth A10VSO140 series is a high-performance, large-displacement variable pump specifically engineered for industrial open-circuit hydraulic systems. As a heavy-duty flagship of the Series 31 platform, it is designed for complex operations requiring sophisticated power management. The core model, A10VSO140DFLR/31R-PPB12N00, features the advanced DFLR (Power, Pressure, and Load Sensing) controller. This control logic enables the pump to modulate displacement automatically based on system load, ensuring the drive motor’s power is utilized optimally. This prevents motor overload and significantly reduces system heat generation, making it the premier choice for industrial presses, metal recycling shears, injection molding machines, and large offshore hydraulic power units (HPU).

Key Technical Advantages:

• DFLR 3-in-1 Intelligent Control: Combines Power Control, Pressure Control, and Load Sensing for precise torque matching, maximizing operational speed while achieving extreme energy savings.

• Rugged Series 31 Platform: Features a reinforced bearing structure and 9-piston rotating group, maintaining exceptional volumetric efficiency and whisper-quiet operation at a rated pressure of 280 Bar.

• Superior Suction Characteristics: The flow paths are optimized for the large 140cc displacement, providing excellent self-priming capabilities at high speeds and significantly reducing cavitation risks.

• Industrial Reinforced Shaft (PPB): Equipped with a high-strength parallel keyed shaft (PPB12 spec) to withstand high-frequency start-stop shocks and torque fluctuations, ensuring long-term stability.

• 100% Through-Drive Capability: Supports full-power through-drive for tandem mounting of auxiliary pumps, facilitating complex multi-circuit hydraulic drive solutions for synchronized actuators.
