The Bosch Rexroth A10VO 71 DR/31L-PSC91N00 (R902401066) is a high-performance axial piston pump designed for medium pressure applications in an open circuit hydraulic system. This all-purpose pump features a swashplate design and is renowned for its low operating noise, long service life, and short control response times, ensuring efficient and reliable operation. The A10VO series is particularly noted for its excellent suction characteristics which contribute to the overall performance and efficiency of the system it's integrated into. With a size of 71, the nominal pressure rating for this model stands at bar while it can handle a maximum pressure of bar. One of the distinctive features of this Bosch Rexroth pump is its through-drive capability, which allows for the mounting of additional pumps up to the same nominal size directly onto it without needing separate drive mechanisms. This modular approach facilitates versatile system configurations and can be particularly beneficial in complex hydraulic systems where space and efficiency are at a premium. The drain ports included in the design are strategically placed to enhance the pump's functionality and maintenance ease. Whether used in mobile or industrial applications, this Bosch Rexroth axial piston pump represents a robust and adaptable solution that meets a wide range of operational demands while delivering consistent performance under varying conditions.
