Product Description
Rexroth A11VO130 Series Heavy-Duty Axial Piston Variable Pump
Product Overview: The Rexroth A11VO130 series is a high-performance swashplate-type axial piston variable pump engineered for Open Circuit high-pressure hydraulic systems. As a core heavy-duty model (130cc) within the A11V family, the A11VO130 is renowned for its exceptional power density and stable performance under extreme conditions. This series is widely utilized in crawler machinery, large-scale construction equipment, and heavy-duty industrial power units (HPUs). Its advanced control options, such as DRS and DSR, ensure a precise match between hydraulic output and load demand, significantly enhancing system efficiency.
Key Technical Advantages:
Heavy-Duty High-Pressure Performance: Built for grueling environments, the A11VO130 supports a rated pressure of 350 Bar and peak cycles up to 400 Bar. Models like the A11VO130DRS/10R-NSD12N00 feature reinforced rotating groups to maintain peak volumetric efficiency under continuous heavy loads.
Precise Pressure & Flow Control (DRS/DSR): Equipped with high-sensitivity regulators. DRS/DSR functionality provides Load Sensing and pressure compensation, dynamically allocating power based on real-time demand to prevent system overheating and drastically reduce energy consumption.
Robust Thru-Drive Capability (K17): Features powerful thru-drive functionality. The K17 suffix (as seen in A11VO130DSR-10L-NSD12K17-02) indicates support for tandem mounting of secondary pumps, optimizing multi-circuit system design and saving installation space.
Superior Reliability Design: Utilizing specially treated swashplate bearings and piston assemblies, the A11VO130 maintains peak mechanical efficiency even in high-temperature or low-viscosity environments, reducing overall maintenance costs.
