The Bosch Rexroth A10VO 74 DFR1/31L-PSC92K04 (R902534939) is a high-quality axial piston variable pump that features a swashplate design for hydrostatic drives in an open circuit. This all-purpose, medium pressure pump is engineered to deliver reliable performance with a size nominal pressure of 280 bar and a maximum pressure of 350 bar. Its through-drive capability allows for the mounting of further pumps up to the same nominal size, increasing versatility and application range. The pump's design emphasizes low operating noise and long service life, making it suitable for environments where noise reduction is critical and durability is required. Its short control response times ensure high efficiency and precise operation in various applications. Additionally, the A10VO series is known for its excellent suction characteristics, which contribute to the overall performance and reliability of the hydraulic system. With drain ports incorporated into its design, this Bosch Rexroth pump maintains effective fluid handling and contributes to the maintenance of system integrity. The A10VO 74 DFR1/31L-PSC92K04 model provides flexibility in application due to its robust construction and advanced engineering, making it an ideal choice for mobile and industrial applications that demand high-performance hydraulic systems with consistent results.
