The Bosch Rexroth AA4VG56HD3D1/32R-NSC52F075D (R902232966) is a high-pressure axial piston pump designed for applications in closed circuits. This particular model features an integrated boost pump which serves to supply both boost and pilot oil, ensuring the system operates efficiently even at low speeds and during start-up phases. The flow direction within the pump changes smoothly as the swashplate moves through its neutral position, enhancing the operational stability and responsiveness of hydraulic systems. This model is equipped with high-pressure relief valves that incorporate a boost function, providing additional safety and performance benefits. The pump also includes an adjustable pressure cutoff as a standard feature, allowing users to tailor the system's pressure settings to specific application requirements. Additionally, a boost pressure relief valve is integrated into the design to further protect against overpressure conditions. The AA4VG56HD3D1/32R-NSC52F075D offers versatility through its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly onto it—this feature simplifies system design by enabling tandem pump configurations without needing extra adapters or couplings. Designed with a swashplate mechanism, this model ensures reliable operation under high-pressure conditions. It has been constructed to meet the SAE standards for the US market, indicating adherence to strict quality and performance criteria. The nominal pressure rating for this unit stands at bar while it can handle maximum pressures up to bar, highlighting its capability in demanding applications. Overall, Bosch Rexroth's AA4VG56HD3D1/32R-NSC52F075D is engineered for durability and efficiency in closed circuit systems where robustness and precision control of hydraulic power are essential.
