Replacement Rexroth A10VO71 & A10VO45 Pump | A10VSO71 | A10VO45DFSR | 100% Interchangeable

High-Quality Replacement Rexroth A10VO & A10VSO Series Piston Pumps

Product Overview: If you are seeking a cost-effective alternative to original Rexroth hydraulic pumps, our A10V series replacement axial piston variable pumps are the perfect solution. Manufactured strictly to OEM standards, these pumps are 100% interchangeable with models such as A10VO71, A10VSO71, and A10VO45. Featured models include the A10VO45DFSR/31R-VSC62K01. With precision-engineered swashplate architecture and high-performance regulators, these pumps deliver pressure response and flow control identical to the original equipment, making them ideal for rotary drilling rig auxiliary systems, concrete pumps, industrial HPUs, and diverse construction machinery.

Key Technical Advantages:

• 100% Interchangeability: Mounting dimensions, shaft specifications, and port locations are identical to the original Rexroth A10V series, allowing for direct “drop-in” replacement without piping modifications.

• Intelligent Control Logic (DFSR/DFR): Equipped with advanced DFSR (Load Sensing & Pressure Compensation) regulators, these pumps match system load in real-time, drastically reducing energy waste and oil heat generation.

• Enhanced Self-Priming: Improved valve plate designs boost suction capabilities at high rotational speeds, ensuring superior volumetric efficiency during intense duty cycles.

• High-Reliability Components: Critical rotating groups (pistons and cylinder blocks) are crafted from premium alloy steel with specialized heat treatment, ensuring long-term service life at a 280 Bar rated pressure.

• Quiet & Low Pulsation: The 9-piston design effectively dampens system pressure ripples, significantly lowering noise levels and improving the work environment.
