The Bosch Rexroth AA4VG56DE4D1/32L-NSC52N003EP-S (R902249686) is a high-pressure axial piston pump designed for closed circuit applications. This particular model features an integrated boost pump which serves to supply both boost and pilot oil, ensuring the flow direction changes smoothly when the swashplate transitions through the neutral position. The unit comes equipped with high-pressure relief valves that include an integrated boost function, enhancing its safety and performance capabilities. Moreover, this Bosch Rexroth pump has an adjustable pressure cutoff as a standard feature, providing additional control and customization based on specific operational requirements. It also includes a boost pressure relief valve for added security and performance reliability. The pump's design allows for through-drive capability, enabling the mounting of additional pumps up to the same nominal size, which can be beneficial for systems requiring multiple pump setups. The swashplate design of this model ensures efficient operation within hydraulic systems. Its size is tailored to handle nominal pressures effectively while also being capable of withstanding maximum pressure peaks without compromise to its integrity or performance. Specifically engineered for the US market, this SAE version adheres to industry standards and specifications relevant to North American applications. With its robust construction and versatile control options, the Bosch Rexroth AA4VG56DE4D1/32L-NSC52N003EP-S is well-suited for demanding applications that require reliable hydraulic power in a closed circuit system. Whether it's used in mobile or industrial environments, this axial piston pump represents precision engineering designed to deliver consistent performance under high-pressure conditions.
