Rexroth A10VNO Series (Series 52) High Suction Variable Piston Pump

Product Overview: The Rexroth A10VNO series is a high-efficiency variable displacement pump engineered specifically for Open Circuit hydraulic systems, belonging to the proven Series 52 family. This series covers essential displacements including 28cc, 45cc (A10VNO45), 63cc, and 85cc. The core advantage of the A10VNO lies in its exceptional self-priming capabilities. The optimized internal flow path design significantly enhances maximum allowable speeds, maintaining high-capacity fluid charging without the need for additional pre-pressure. Integrating advanced control options like DFR1 Load Sensing, these pumps ensure flow output is precisely synchronized with load demand, making them the premier choice for mobile hydraulics and compact power units.

Key Technical Advantages:

• Superior Self-Priming Speed: Specifically optimized for high-speed operation. Fluid dynamic improvements in the internal structure reduce suction resistance, effectively preventing cavitation at high RPMs and drastically improving system response times.

• Heavy-Duty Mid-Pressure Reliability: Rated for an operating pressure of 210 Bar (21 MPa) with peak capabilities reaching 250 Bar, achieving a perfect balance between lightweight design and high power output.

• Precise Control Logic (DFR1):

  • Load Sensing (DFR1): Models like the A10VNO45DFR1 feature integrated pressure and flow compensation, delivering only the power required by the system, which slashing heat generation and minimizing energy waste.

• Low Noise & Longevity: Utilizing Rexroth’s patented valve plate noise-reduction technology, maintaining quiet and stable performance even at high pressure. Reinforced bearing structures ensure an extended service life in harsh environments.

• Compact Installation Solutions: Features extreme power density. The through-drive architecture supports tandem mounting of a secondary pump (piston or gear), streamlining complex multi-circuit system integration.
