The Bosch Rexroth AA4VG71HD3DMT1/32L-NSF52F041D-S (R902113374) is a high-pressure axial piston variable pump designed specifically for applications in closed circuits. This pump features an integrated boost pump which serves both to supply boost and pilot oil, ensuring the flow direction changes smoothly when adjusting the swashplate through its neutral position. It is engineered to provide reliable performance with its high-pressure relief valves that come with an integrated boost function. Moreover, this model includes an adjustable pressure cutoff as a standard feature, enhancing its safety and efficiency during operation. The boost pressure relief valve contributes to the system's protection by maintaining optimal operational pressure levels. For added versatility, the AA4VG71HD3DMT1/32L-NSF52F041D-S offers a through-drive capability, allowing for the mounting of additional pumps up to the same nominal size, which can be particularly beneficial for complex hydraulic systems requiring multiple pump configurations. The swashplate design of this Bosch Rexroth pump allows for precise control over hydraulic fluid flow and pressure, making it suitable for demanding applications that require exacting performance standards. With a nominal pressure of 400 bar and a maximum pressure of 450 bar, this SAE version is tailored for the US market, adhering to industry standards and specifications required in North America. Its robust construction and advanced design make it a reliable component in various applications requiring high-pressure operation within closed hydraulic circuits.
