Rexroth A10VSO & A4VSO Pump | A10VSO18, A10VSO140 | 280-350 Bar Variable Pump

Rexroth A10VSO & A4VSO Series Industrial Axial Piston Variable Pump

Product Overview: The Rexroth A10VSO and A4VSO series are the gold standard for swashplate-designed axial piston variable pumps in global industrial Open Circuit systems. As the flagship of the proven Series 31 family, they are renowned for exceptional power density and superior control precision. By utilizing DFR Load Sensing or DRG Remote Pressure Control, these pumps dynamically sense system demand, delivering only the required power to drastically reduce energy consumption and heat generation. From the compact 18cc (A10VSO18) to the heavy-duty 140cc (A10VSO140), they provide long-term, reliable power.

Key Technical Advantages:

• Versatile Intelligent Controls (DFR/DR/DRG):

  • Model A10VSO18DFR: Features integrated Load Sensing to dynamically adjust displacement based on flow demand, making it the premier choice for energy-efficient power units.

  • Model A10VSO140DR/DRG: Equipped with Pressure Compensation and Remote Pressure Control (DRG), allowing operators to switch system pressure levels seamlessly from a remote control panel.

• Heavy-Duty Industrial Performance: Engineered for continuous high-pressure industrial cycles. A10VSO supports a rated pressure of 280 Bar, while the A4VSO series caters to even more demanding heavy-duty requirements. Reinforced rotating groups ensure peak volumetric efficiency under 24/7 operation.

• Flexible Installation Specs (PPB): Features superior thru-drive capability. Specifications like PPB12N00 allow for tandem mounting of a secondary pump, facilitating streamlined multi-circuit system integration.

• Advanced Noise Reduction: Utilizing Rexroth’s patented dampening technology and optimized flow paths, the pumps maintain whisper-quiet operation even at large displacements like 140cc, ideal for noise-sensitive indoor environments.
