Rexroth A10VSO Double Pump | AA10VSO45, A10VSO10 | DR Pressure Control | Variable Piston Tandem Pump

Rexroth A10VSO Series High-Efficiency Double Axial Piston Variable Pumps

Product Overview: The Rexroth A10VSO series double pump (tandem configuration) is the ideal solution for multi-circuit power distribution in industrial open-circuit systems. Utilizing through-drive technology, we combine the high-performance AA10VSO45 (Series 31) with the compact A10VSO10 (Series 52). Featured combinations like the AA10VSO45DR/31R-PKC62K01 coupled with an A10VSO10DR/52R-PUC64N00E deliver unmatched versatility. This configuration allows a single electric motor to drive two independently controlled hydraulic circuits—where the lead pump provides high-pressure main flow and the trailing pump handles auxiliary or pilot circuits. It is widely used in CNC machine tools, small-to-medium presses, injection molding machines, and complex industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

• Efficient Through-Drive Integration: Featuring standard PKC/PUC through-drive specifications, supporting 100% power transfer. This allows flexible coupling of different displacements, significantly saving installation space and motor costs.

• Precise DR Pressure Control: Both pumps are equipped with independent DR (Pressure Cut-off) regulators, automatically modulating displacement based on individual circuit loads to maintain constant pressure and minimize energy waste.

• Cross-Platform Performance: The Series 31 (45cc) front pump offers heavy-duty industrial longevity, while the Series 52 (10cc) rear pump provides lightning-fast response and a wide speed range, ensuring total system stability under high-frequency cycles.

• Whisper-Quiet Operation: The optimized 9-piston architecture and pre-compression chamber design maintain industry-leading low noise levels, even when both pumps are operating at full load.

• Modular Maintainability: The tandem design allows for the independent servicing or replacement of the rear pump without dismantling the entire pump group, reducing the risk of extended downtime.
