The Bosch Rexroth A A10V O 71 DFR /31L-VSC91N00 (R902502700) is a high-performance axial piston unit designed to operate as a variable displacement pump in open circuit hydraulic systems. This medium pressure pump is characterized by its robust swash plate design, which allows for stepless adjustment of flow proportional to the drive speed and displacement. The unit's size and displacement are optimized for efficient operation, with a nominal pressure of 280 bar and a maximum pressure of 350 bar, suitable for various applications requiring precise hydraulic control. The A A10V O 71 DFR /31L-VSC91N00 boasts a low operating noise level and features a pressure flow controller without through drive, ensuring smooth and quiet performance. It is equipped with FKM standard sealing materials that contribute to its long service life and reliability in demanding environments. The pump's control device, the DR F controller XT open, ensures short control times with quick response, enhancing the overall efficiency of the system it is integrated into. Designed with an ISO SAE mounting flange and featuring working ports B flange SAE and S flange SAE, this pump provides versatile connection options for ease of installation. Its rotational speed capabilities further complement its adaptability across various applications. With a fixed minimum and maximum displacement setting, the A A10V O 71 DFR /31L-VSC91N00 maintains consistent performance parameters. The product's weight stands at approximately 36 kilograms, making it a substantial yet manageable component within hydraulic systems. Its counterclockwise rotation when viewing from the shaft end ensures compatibility with standard system designs. In summary, the Bosch Rexroth A A10V O 71 DFR /31L-VSC91N00 is an all-purpose medium pressure pump that excels in open circuit applications where variable volume flow and precise hydraulic control are required. Its durable construction paired with efficient fluid dynamics makes it an essential component for reliable hydraulic operations.
A10V O, variable displacement unit, open circuit, medium pressure, size: 71 cm³, pressure flow controller, without through drive
A10VO is a variable pump with axial piston transmission in swash plate design for hydrostatic drives in the open circuit. The flow is proportional to the drive speed and the displacement. By adjusting the swash plate, the flow can be steplessly changed.
