The Bosch Rexroth A A10VSO 45 DFR1/31R-PPA12K25 -S1134 (R902407878) is a state-of-the-art axial piston variable pump with a swashplate design for hydrostatic transmissions in open circuits. This all-purpose medium pressure pump is designed to excel in a range of applications thanks to its impressive features, including the ability to facilitate through-drive for the mounting of additional pumps up to the same nominal size, which enables a versatile use in complex hydraulic systems. With its size 45, the pump operates at a nominal pressure of 280 bar and can withstand a maximum pressure of up to 350 bar, ensuring reliable performance under demanding conditions. The A10VSO series is known for its low operating noise levels, contributing to improved workplace environments and meeting stringent noise reduction requirements. Durability is another key aspect of this Bosch Rexroth pump, as it promises a long service life due to its robust construction and high-quality materials. The short control response times are indicative of its high efficiency and responsiveness, making it suitable for applications requiring precise hydraulic control. Furthermore, the excellent suction characteristics are critical for maintaining consistent operation and protecting the system from cavitation-related damage. The presence of drain ports adds to the maintenance-friendly design by facilitating fluid drainage when necessary. The metric version of this pump ensures compatibility with standardized systems around the globe, simplifying installation and integration into various machinery setups. Whether utilized in mobile or industrial applications, the Bosch Rexroth A10VSO series pump delivers performance that engineers and technicians can rely on for efficient and smooth hydraulic operations.
