A11VO axial piston variable displacement pumps are available in 40, 60, 75, 95, 130, 145, 190 and 260 series to meet different hydraulic system requirements.
Operating at a nominal pressure of 350 bar and up to 400 bar, the A11VO series provides powerful power for demanding applications. Its open piston pump design ensures efficient operation and consistent performance under varying conditions.
The A11VO is a variable displacement axial piston pump with a swash plate design. The Rexroth A11VO high-pressure Rexroth piston pump operates under self-priming conditions for excellent tank pressurization and can optionally be equipped with a charge pump (impeller) to provide stable, continuous hydraulic power to the system.
Comprehensive control options are also available. Its power control option is externally adjustable, meaning power can be fine-tuned as needed even while the pump is running. This design greatly increases the convenience and efficiency of operation. Its thru-shaft drive design allows it to be easily used with gear pumps and axial flow pumps for 100% drive through.
The output flow rate of the Rexroth A11VO piston pump is directly proportional to the drive speed, which means that the change in flow rate is directly related to the drive speed. Between qV max and qV min, unlimited variations are possible, allowing the pump to excel in a variety of applications, whether high or low flows are required.
The Rexroth A11VO piston pump demonstrates its performance in open circuit hydraulic systems thanks to its swash plate design, excellent control options, efficient through-shaft transmission and proportional relationship between flow and speed. It works brilliantly in mobile applications and other systems requiring hydrostatic actuation.
