The Bosch Rexroth AA4VG71EP4D1/32R-NSF52F011DH (R902205981) is a high-pressure axial piston pump designed for applications in closed circuits. This particular model features an integrated boost pump, which supplies both boost and pilot oil, ensuring consistent and efficient operation. The pump's design allows for smooth flow direction changes as the swashplate moves through its neutral position, enhancing machine controllability. With nominal pressure rated at bar and maximum pressure at bar, the AA4VG71EP4D1/32R-NSF52F011DH is engineered to withstand demanding operational conditions. The pump is equipped with high-pressure relief valves that incorporate a boost function, providing an additional layer of system protection. An adjustable pressure cutoff comes standard with this model, offering customizable control over the hydraulic system's performance. Additionally, this Bosch Rexroth pump includes a boost pressure relief valve and features a through-drive capability that permits the mounting of further pumps up to the same nominal size without compromising space or efficiency. This feature is particularly beneficial for systems requiring multiple hydraulic functions. The SAE version of this pump is tailored for the US market, adhering to industry standards and ensuring compatibility with a wide range of equipment. Its swashplate design contributes to its robustness and reliability in various applications. Overall, the AA4VG71EP4D1/32R-NSF52F011DH represents a versatile solution for those requiring a high-performance hydraulic pump in closed circuit systems.
