Product Description
Rexroth A10VSO28 Series 31 Variable Displacement Piston Pumps
Product Overview: The Rexroth A10VSO28 is one of the most widely utilized mid-pressure variable pumps in industrial hydraulic systems. As a cornerstone of the Series 31 lineup, it combines exceptional compactness with high performance. This pump supports two primary control modalities: DR (Pressure Control) and DFR (Load Sensing). Featured models like the A10VSO28DR/31R-PPA12N00 deliver proven results. By modulating the swashplate angle for precise flow control, the DR regulator rapidly reduces displacement to zero once the preset pressure is reached, significantly minimizing standby power consumption and system heat generation. It is the premier choice for CNC machine tools, hydraulic fixtures, small presses, and industrial power units (HPUs).
Key Technical Advantages:
Versatile Control Options: Offers DR (Pressure Control) for maintaining system stability and DFR (Load Sensing) for precisely matching flow to actuator demand, maximizing energy efficiency.
Robust Pressure Ratings: Rated for continuous operation at 280 Bar (4060 PSI) with peak capabilities up to 350 Bar (5100 PSI), suitable for most industrial duty cycles.
Low-Noise Swashplate Design: The 9-piston architecture effectively dampens pressure ripples, ensuring minimal decibel levels even at full speed in factory environments.
High Efficiency & Low Leakage: Precision-engineered valve plates and piston assemblies ensure superior volumetric efficiency and extend the service life of hydraulic fluids.
Flexible Through-Drive: Supports tandem mounting of additional pumps (such as gear pumps), facilitating the construction of multi-stage hydraulic power sources.
