The Bosch Rexroth A A10V O 71 DFR /31L-PSC91N00 (R902400410) is a high-performance axial piston variable pump that employs a swashplate design for hydrostatic drives in an open circuit configuration. This all-purpose medium pressure pump is engineered to deliver reliable performance with its size 71, which operates effectively within a nominal pressure of 280 bar and can handle maximum pressures up to 350 bar. It stands out for its through-drive capability, allowing the mounting of additional pumps up to the same nominal size, facilitating versatile system configurations. Designed with efficiency in mind, the A A10V O 71 DFR /31L-PSC91N00 features excellent suction characteristics that contribute to its long service life and low operating noise, making it suitable for applications where noise sensitivity is a concern. The pump's short control response times ensure precise operation and contribute to overall system responsiveness. Furthermore, this Bosch Rexroth pump includes drain ports which are essential for maintaining internal pressure and fluid dynamics within the hydraulic system. Its robust construction and meticulous engineering are tailored to meet the demands of various applications requiring consistent and dependable hydraulic power. The combination of these features makes it an ideal choice for users seeking a durable and efficient solution for their medium pressure hydraulic needs.
