Rexroth A10VO28 Pump | A10VO28DR/52R, A10VO28DFR/31R | Axial Piston Variable Pump

Rexroth A10VO28 Series Axial Piston Variable Displacement Pump

Product Overview: The Rexroth A10VO28 series is one of the most widely utilized axial piston variable displacement pumps globally. Featuring a swashplate design for open-circuit hydraulic systems, this series includes high-performance models like the A10VO28DR/52R-VSC62K01 (Series 52, high power density) and the reliable A10VO28DFR/31R-VSC62K01-S052 (Series 31, customized load sensing). Whether in injection molding machines, compact construction equipment, or industrial power units, these pumps deliver exceptional system response and energy efficiency through precise displacement regulation.

Key Technical Advantages:

• Versatile Control Options:

  • DR (Pressure Control): Automatically maintains preset system pressure; displacement swivels back to zero at the pressure cut-off, protecting the system and saving energy.

  • DFR (Load Sensing): Modulates output based on the actual flow demand of the actuators, ensuring high efficiency during multi-function operations.

• Cross-Series Performance Optimization:

  • Series 52: Optimized for modern machinery with higher rated pressure capabilities and a more compact envelope.

  • Series 31: A mature, highly compatible design that remains the industry standard for field replacements.

• Exceptional Low-Noise Engineering: Optimized valve plate designs and VSC62K housing structures ensure minimal fluid pulsation and mechanical noise, even at full operating pressures.

• 100% OEM-Standard Compatibility: Manufactured to strict Rexroth mounting specifications (e.g., VSC62K01 porting), ensuring spline shafts and flanges align perfectly for seamless drop-in replacement.

• Wear-Resistant & Long Life: Critical rotating groups (pistons, cylinders, and slippers) undergo high-intensity hardening to withstand high-frequency cycles and harsh fluid environments.
