The Bosch Rexroth A A10V O 71 DFR /31L-VSC92N00 (R902502710) is a meticulously engineered variable displacement pump designed for hydrostatic drives in open circuits. This medium-pressure unit features a size of 71 cm³ and is equipped with a DR F controller for precise control operations. The pump operates with a splined shaft and can be mounted via an ISO SAE, 2-hole flange, ensuring compatibility with standard systems. Crafted for versatility, the AVO model boasts excellent suction characteristics and is optimized to deliver consistent performance with minimal noise disruption. The flow of this axial piston unit is directly proportional to the drive speed and displacement, which can be seamlessly adjusted by altering the swash plate angle. With its fixed displacement settings, this pump maintains reliable operation across various applications. The A A10V O 71 DFR /31L-VSC92N00 supports counterclockwise rotation when viewed from the shaft end and operates without an internal drain line or through drive for additional pumps. It utilizes FKM as the standard sealing material, ensuring durability under diverse operating conditions. The working ports are designed to accommodate B flange SAE and S flange SAE connections. This standard version of the pump underscores its robustness with a nominal pressure of 280 bar and a maximum pressure capacity of up to 350 bar, suitable for open circuit systems. With its compact weight of 33.5 kg and streamlined dimensions, it offers ease of installation without compromising on power or efficiency. Its design focuses on long service life, short control response times, and low operating noise levels – all crucial attributes that contribute to its reliability in demanding environments. In summary, the Bosch Rexroth A A10V O 71 DFR /31L-VSC92N00 is an all-purpose medium-pressure pump that excels in providing stable hydraulic power with quick response controls in open circuit applications.
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.
