The Bosch Rexroth AA4VG71HWD1/32R-NSF52F021D-S (R902205989) is a high-pressure axial piston pump designed for applications in closed circuits. It features an integrated boost pump which serves the dual purpose of providing boost and pilot oil supply, ensuring the system operates efficiently even at low speeds and during start-up phases. The flow direction within this pump changes smoothly as the swashplate transitions through the neutral position, contributing to the operational precision and smooth performance of hydraulic systems. This model is equipped with high-pressure relief valves that incorporate a boost function, which not only enhances the safety of operations by limiting maximum pressure but also improves system reliability. Additionally, it comes standard with an adjustable pressure cutoff feature, allowing for customization according to specific application requirements. A boost pressure relief valve is also included to further manage system pressures effectively. Designed with versatility in mind, the AA4VG71HWD1/32R-NSF52F021D-S offers a through-drive capability that enables the mounting of additional pumps up to the same nominal size directly on its housing. This feature allows for a compact and efficient design solution when multiple pumps are required within a system. The pump operates at a nominal pressure of 400 bar and can handle maximum pressures up to 450 bar, making it suitable for demanding applications that require robust performance under high-pressure conditions. Its swashplate design is optimized for durability and consistent operation over time. This particular SAE version is tailored for the US market, ensuring compliance with industry standards and facilitating integration into various equipment designs. With its comprehensive range of controls and options, this Bosch Rexroth axial piston pump represents a reliable choice for engineers looking to implement advanced hydraulic solutions in their machinery or systems.
