Product Description

Rexroth A11VSO28DR/31R Series Variable Axial Piston Pumps

Product Overview: The Rexroth A10VSO28 is one of the most reliable and widely utilized axial piston variable displacement pumps in global industrial hydraulic systems. As a cornerstone of the Series 31 platform, this model is specifically engineered for medium-to-high pressure open-circuit applications, delivering exceptional volumetric efficiency paired with superior quiet operation. The featured model A10VSO28DR/31R-PPA12N00 (Material Number: R910903163) integrates the classic DR Pressure Control regulator, which automatically modulates flow based on system pressure demand, significantly reducing energy consumption and heat generation. It is the premier choice for CNC machine tools, plastics processing machinery, metal forming presses, and diverse industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

  • Precise DR Pressure Control: Once the system reaches the preset pressure, the pump automatically shifts to minimum displacement, ensuring system safety and maximizing energy efficiency.

  • Quiet Industrial Architecture: Optimized swashplate design and 9-piston arrangement minimize hydraulic ripples, maintaining industry-leading low decibel levels even under full load.

  • Superior Power-to-Weight Ratio: The compact frame combines lightweight design with high structural integrity, facilitating easy installation in space-constrained hydraulic power stations.

  • Extended Service Life: Equipped with reinforced bearings and specialized piston group treatments, these pumps maintain peak performance under continuous heavy-duty cycles and varied hydraulic oil conditions.

  • Universal Compatibility: Adheres to standard SAE 2-bolt mounting and shaft specifications (PPA12N00), providing a seamless “drop-in” replacement for existing industrial hydraulic systems.
