Rexroth A10VO28 Series Pump | A10VO28DR, A10VO28DFR | 280 Bar Variable Pump

Rexroth A10VO28 Series Axial Piston Variable Pump

Product Overview: The Rexroth A10VO28 series is one of the most widely utilized medium-pressure axial piston variable pumps in the global hydraulic industry. As a core model within the Series 31 and Series 52 (displacement 28cc), it is renowned for its compact design, low-noise operation, and rapid response times. Engineered specifically for Open Circuit systems and integrated with advanced DR Pressure Control or DFR Load Sensing, this series ensures a precise match between flow and pressure demand, significantly reducing energy consumption for loaders, machine tools, and industrial power units (HPU).

Key Technical Advantages:

• Precise Control Modulation (DR/DFR): * The A10VO28DR/52L-PSC62N00 model features a DR pressure compensator, automatically reducing displacement to a minimum once the preset pressure is reached to maintain constant output.

  • The A10VO28DFR/31L-PSC62K02 integrates Load Sensing (LS) functionality, dynamically modulating flow based on real-time actuator demand to drastically minimize relief losses and heat generation.

• Compact & High-Efficiency: The optimized swashplate design provides exceptional power density, allowing for a continuous operating pressure of 280 Bar within a small installation footprint.

• Superior Noise Reduction: Utilizing Rexroth’s patented valve plate technology, the A10VO28 maintains low decibel levels even under high-pressure conditions, making it ideal for quiet indoor industrial environments.

• Robust Thru-Drive Capability (K02): The K02 suffix indicates superior thru-drive functionality, supporting tandem mounting of secondary pumps (gear or piston types) to streamline multi-circuit power distribution.
