The Bosch Rexroth AA4VG40EP4DT1/32R-NSC52F013PH (R902148817) 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 consistent and reliable operation. The flow direction within this pump changes smoothly as the swashplate transitions through the neutral position, enhancing the control and efficiency of the system. Equipped with high-pressure relief valves that include an integrated boost function, this pump ensures safety and optimal performance under varying conditions. It also comes standard with an adjustable pressure cutoff, allowing for precise control over the maximum system pressure to suit specific application requirements. Additionally, the AA4VG40EP4DT1/32R-NSC52F013PH includes a boost pressure relief valve and offers a through-drive capability. This feature permits the mounting of additional pumps up to the same nominal size, facilitating versatile configuration options for complex hydraulic systems. The swashplate design is another critical aspect of this model, contributing to its robustness and reliability in demanding environments. With its nominal pressure rated at bar and maximum pressure rated at bar, this SAE version is tailored for the US market. It exemplifies engineering excellence in hydraulic systems where high performance and endurance are essential. The Bosch Rexroth AA4VG40EP4DT1/32R-NSC52F013PH stands out as a sophisticated component suitable for a wide array of applications requiring precise hydraulic fluid control under high-pressure conditions.
