Rexroth A10VSO & ALA10VO Series 31 Variable Displacement Piston Pumps

Product Overview: The Rexroth A10V series variable axial piston pumps are the driving force of modern hydraulic systems. This selection features the A10VSO (45cc/100cc) series for stationary industrial power units and the high-performance ALA10VO (71cc) series optimized for mobile machinery. Flagship models include the A10VSO45DFR1 and A10VSO100DFR1 with Load Sensing control, alongside the ALA10VO71DFLR, which integrates pressure, flow, and power modulation. Utilizing a proven swashplate design, these pumps offer stepless displacement regulation, automatically optimizing flow delivery based on real-time demand for heavy-duty machine tools, injection molding, mini-excavators, and material handling equipment.

Key Technical Advantages:

• Intelligent Control Logic (DFR1/DFLR): The DFR1 (Load Sensing) ensures flow follows demand, drastically reducing overflow energy loss; the DFLR (Power Control) automatically adjusts displacement based on system pressure to prevent engine or motor stalling.

• High-Pressure Performance: Rated for continuous operation at 280 Bar (4060 PSI) with peak capabilities up to 350 Bar (5100 PSI), ensuring high stability under heavy duty cycles.

• Superior Low-Noise Design: Optimized 9-piston rotating groups minimize noise levels and pressure ripples during high-pressure cycles, significantly improving the work environment.

• Exceptional Power Density: Compact housing with integrated high-performance regulators supports through-drive options, facilitating multi-pump tandem configurations.

• Full Lifecycle Reliability: Critical friction pairs undergo specialized hardening processes, ensuring an extended service life and minimal internal leakage even in harsh, continuous operations.
