Rexroth A10VO28 Series 31 Axial Piston Variable Pumps

Product Overview: The Rexroth A10VO28 series is a high-performance axial piston variable displacement pump designed for open-circuit hydraulic systems in both industrial and mobile applications. As part of the legendary Series 31, the A10VO28 is world-renowned for its “Superior Power-to-Weight Ratio” and “Precise Load-Sensing Capability.” With a displacement of 28 cm³/rev, prominent models include the A10VO28DR (Pressure Control), A10VO28DFR (Pressure & Flow Control), and A10VO28-DFR1. These pumps are widely utilized in medium-sized hydraulic power units (HPU), injection molding auxiliary systems, harvester drives, and automated production lines, delivering stable power output at pressures up to 280 Bar.

Key Technical Advantages:

• Versatile Control Combinations: Available with DR (Pressure Control) and DFR/DFR1 (Load-Sensing), modulating displacement precisely to match actuator demand, significantly lowering energy waste.

• Excellent Suction & Speed Characteristics: Optimized internal flow channels ensure superior self-priming performance at rated speeds, effectively preventing cavitation and extending service life.

• Whisper-Quiet Operation: Features noise-suppression valve plate technology, maintaining low decibel output even under full load at high pressures to meet environmental standards.

• Compact Structural Design: Series 31 optimizes the swashplate mechanism to reduce installation footprint while enhancing heat dissipation efficiency in confined spaces.

• Standardized Compatibility: Strictly adheres to SAE or ISO mounting standards (e.g., VSC, PSC configurations), ensuring 100% “drop-in” replacement for original systems.
