The Bosch Rexroth A10VO 74 DFR1/31L-PSC92K04 (R902534938) is a high-quality axial piston variable pump, designed with a swashplate system for hydrostatic drives in an open circuit. This all-purpose medium pressure pump is characterized by its robustness and reliability, featuring a nominal pressure of 280 bar and a maximum pressure of 350 bar. It is engineered to provide low operating noise and long service life, ensuring efficient performance in various applications. The A10VO series is known for its short control response times and excellent suction characteristics, which make it suitable for a wide range of operational demands. The R902534938 model includes a through drive option, which allows the mounting of further pumps up to the same nominal size directly to the rear of the pump without requiring an additional adapter, thus offering versatility in complex hydraulic systems. This particular model is well-suited for use in mobile applications such as construction machinery as well as industrial applications including machine tools and production machinery where precision and efficiency are critical. Its optimized design ensures minimal energy consumption while maintaining peak operational performance. With drain ports incorporated into its design, this pump maintains optimal fluid handling capabilities, enhancing its overall functionality and durability. The A10VO 74 DFR1/31L-PSC92K04 represents Bosch Rexroth's commitment to advanced engineering and manufacturing excellence, providing users with a reliable solution for their hydraulic system needs.
