The Bosch Rexroth AA4VG125HD3DMT1/32L-NSF52F021D-S *FNI* (R902134137) is a high-pressure axial piston variable pump designed for applications in closed circuits. This particular model is tailored for the SAE version suitable for the US market, reflecting its adherence to specific standards and compatibility with regional systems. The pump features an integrated boost pump which ensures a consistent supply of boost and pilot oil, essential for its smooth operation. The swashplate design allows the flow direction to change seamlessly as the swashplate moves through the neutral position, ensuring efficient control and responsiveness. With a nominal pressure of bar and a maximum pressure bar, this Bosch Rexroth pump is built to withstand demanding conditions while delivering reliable performance. The inclusion of high-pressure relief valves with an integrated boost function contributes to its robust safety features, preventing overpressure incidents. Moreover, these pumps come with an adjustable pressure cutoff as standard, offering additional control over operational parameters. The AA4VG125HD3DMT1/32L-NSF52F021D-S *FNI* also includes a boost pressure relief valve and possesses the capability of through drive, which permits the mounting of further pumps up to the same nominal size—a feature that significantly enhances system flexibility and expansion possibilities. This versatility makes it suitable for various applications requiring precise hydraulic fluid control under high-pressure conditions. In summary, this Bosch Rexroth axial piston variable pump stands out due to its integration of advanced features such as an integrated boost pump, adjustable pressure cutoffs, high-pressure relief valves with boost functions, and capability for through drive installations. Its design adheres strictly to closed circuit requirements in the US market's SAE version.
