The Bosch Rexroth A A10V O 71 DFR /31R-PKC92N00 (R902544780) is a high-performance axial piston pump designed for open circuit applications. This all-purpose medium pressure pump is recognized for its durability and reliability, featuring a nominal pressure of up to 280 bar and a maximum pressure of 350 bar. Its robust construction ensures a long service life while maintaining low operating noise, making it suitable for environments where noise reduction is critical. The A A10V O 71 DFR /31R-PKC92N00 is engineered with advanced swashplate design technology that provides excellent suction characteristics, ensuring efficient operation even at the lowest speed ranges. The pump's short control response times are ideal for applications requiring precise hydraulic fluid control. Additionally, it comes equipped with drain ports that facilitate maintenance and enhance the pump's overall performance. One of the standout features of this model is its through-drive capability, which allows for the mounting of further pumps up to the same nominal size directly onto this unit without requiring additional adapters or couplings. This feature simplifies system design and can lead to cost savings in terms of space and materials. Bosch Rexroth's attention to detail in manufacturing processes ensures that each A A10V O 71 DFR /31R-PKC92N00 meets stringent quality standards, providing users with a reliable solution for their hydraulic system needs. Whether used in mobile or industrial settings, this pump is designed to deliver consistent performance under demanding conditions.
