The Bosch Rexroth A A10V O 71 DFR /31R-VSC92K68 (R902506697) is a state-of-the-art variable displacement pump designed with an axial piston swashplate mechanism, tailored for hydrostatic drives in open circuit applications. This versatile pump is engineered to deliver variable flow rates that are directly proportional to its drive speed and displacement, which can be seamlessly adjusted via the swashplate angle. With a size of 71 cm³, it stands out for its low operating noise and high efficiency. The pump features a pressure flow controller and comes equipped with a DR F controller for precise control, ensuring short response times and reliable performance. It is built with an FKM standard sealing material that promises durability and resistance to harsh conditions. The A10V O 71 DFR /31R-VSC92K68 operates effectively within a working pressure range suitable for medium pressure requirements. This model's design includes a through-drive option labeled 'K,' allowing for the mounting of additional pumps up to the same nominal size, thus enabling versatile configuration options within hydraulic systems. The pump's working ports are designed with B flange SAE and S flange SAE standards, while the mounting flange conforms to ISO 4-bolt standards. Notably, this model is crafted to maintain low noise levels during operation while ensuring a long service life and quick control response times—an attribute that underscores Bosch Rexroth's commitment to high-quality engineering. Its excellent suction characteristics are complemented by strategically placed leakage and drain ports that contribute to its overall reliability and maintenance ease. With its robust construction, the A A10V O 71 DFR /31R-VSC92K68 operates with an exceptional balance of power and precision in various applications requiring consistent hydraulic performance. Its clockwise rotation when viewed from the shaft end makes it compatible with standard system configurations. This model's all-purpose medium pressure capabilities make it suitable for nominal pressures of up to bar while being able to withstand maximum pressures of bar in open circuit systems.
A10V O, variable displacement unit, open circuit, medium pressure, size: 71 cm³, pressure flow controller, with 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.
