Rexroth A10VSO Series Pump | A10VSO140, A10VSO10 | 280 Bar Variable Piston Pump

Rexroth A10VSO Series Variable Axial Piston Pump

Product Overview: The Rexroth A10VSO series is the premier power source for industrial Open Circuit hydraulic systems. This series covers a comprehensive displacement range from the compact 10cc (A10VSO10) to the high-capacity 140cc (A10VSO140), spanning the proven Series 31, 32, and 52. Renowned for its superior power-to-weight ratio, extended service life, and flexible control options like DR (Pressure Control) and DRG (Remote Pressure Control). By automatically adjusting displacement to match load demand, A10VSO pumps significantly reduce energy consumption, making them the preferred choice for injection molding, metal forming, and heavy-duty power units.

Key Technical Advantages:

• Precise Control Logic (DR/DRG): * DR Pressure Regulator (A10VSO140DR): Automatically de-strokes the pump when the preset pressure is reached, minimizing energy waste and heat generation.

  • DRG Remote Regulator (A10VSO10DRG): Facilitates remote pressure modulation via an external pilot valve, drastically increasing system layout flexibility.

• Heavy-Duty Industrial Reliability: Rated for an operating pressure of 280 Bar (28 MPa) with peak capabilities reaching 350 Bar. Reinforced rotating groups and bearings ensure an extended service life under grueling conditions.

• Low Noise & Low Pulsation: Utilizes patented valve plate noise-reduction technology to maintain smooth and quiet power delivery even at high operating pressures.

• Robust Through-Drive Capability: The “N00” code represents standard configuration, while also supporting tandem mounting of secondary pumps (piston or gear) for streamlined multi-circuit integration.

• Rapid Response Times: Features ultra-short control response cycles, allowing the pump to react instantaneously to flow demand changes and boost overall production efficiency.
