Rexroth A10V Series Pump | A10VSO71, A10VO100 | DFR1, DFLR Variable Piston Pump

Rexroth A10V Series (Series 31) Variable Displacement Piston Pump

Product Overview: The Rexroth A10V series is one of the most widely utilized variable displacement piston pumps in the global hydraulic industry. As part of the classic Series 31 design, it features core displacements such as 71cc (A10VSO71) and 100cc (A10VO100). Specifically engineered for open-circuit applications, the A10V series operates at a rated pressure of 280 Bar. With its superior power density and diverse control mechanisms—such as DFR1 (Pressure/Flow Control) and DFLR (Power Control)—this series significantly reduces system energy consumption, minimizes heat generation, and extends the overall service life of the machinery.

Key Technical Advantages:

• Precision Variable Control Modalities:

  • DFR1 (A10VSO71DFR1): Features pressure and flow compensation with Load Sensing (LS) capability, delivering only the flow required by the actuator for maximum energy efficiency.

  • DFLR (A10VO100DFLR): Integrates pressure, flow, and constant power control to prevent drive motor overload, ideal for heavy-load industrial cycles.

• Heavy-Duty Reliability & Compact Design: Rated for an operating pressure of 280 Bar (28 MPa) with peak capabilities up to 350 Bar. The compact swashplate architecture offers an exceptional power-to-weight ratio.

• Flexible Sealing & Configurations (VPA/VUC):

  • Equipped with high-grade FKM (Viton) seals, ensuring superior resistance to high temperatures and aggressive hydraulic fluids for long-term sealing integrity.

• Low-Noise Operation: The acoustically optimized housing design ensures industry-leading low noise levels even at full load, enhancing the workplace environment.

• Through-Drive Capability: Supports tandem mounting of additional piston or gear pumps, allowing for easy integration of multi-circuit power requirements.
