Rexroth A10VO Series Medium-High Pressure Axial Piston Variable Pump

Product Overview: The Rexroth A10VO series is a field-proven swashplate axial piston variable pump designed specifically for Open Circuit applications in both industrial and mobile machinery. Renowned for its exceptional power-to-weight ratio, ultra-low operational noise, and extended service life, the A10VO has become the global standard for hydraulic systems. Whether the Series 52 A10VO28 or the Series 31 A10VO74, this pump ensures maximum system efficiency while significantly reducing energy waste through versatile control options.

Key Technical Advantages:

• Versatile Control Logic: Models like the A10VO28DFR1/52R-VSC62N00 are equipped with Pressure/Flow Compensators (DFR1), automatically adjusting displacement based on real-time actuator load. The A10VO74DFLR/31R-VSC44N00 variant supports Constant Power Control (DFLR), preventing engine or motor overloads.

• Superior Noise Reduction Technology: Featuring an acoustically optimized housing and precision-ground piston groups. Even at a rated pressure of 280 Bar, the pump maintains minimal decibel levels—perfect for indoor factory environments.

• Thru-Drive Capability: The A10VO series supports thru-drive connections, allowing for the tandem mounting of gear pumps or additional piston pumps to achieve a compact layout for multi-circuit systems.

• Flexible Rotation & Mounting: Available in models like the A10VO45DFR1/50L-PUC12N00 (CCW rotation L) and various Clockwise (R) configurations. Compliant with standard SAE or ISO mounting specifications, ensuring 100% physical compatibility with existing power units.
