The Bosch Rexroth AA4VG90EP4D1/32R-NSF52F001DH-S (R902122652) is a highly efficient axial piston variable pump designed for hydrostatic drives in closed circuits. This particular model features an integrated boost pump that ensures a consistent boost and pilot oil supply, enhancing the overall reliability and performance of the hydraulic system. The flow direction within the pump transitions smoothly as the swashplate moves through the neutral position, which contributes to the precise control of machine movements. Equipped with high-pressure relief valves that include an integrated boost function, this model ensures protection against pressure spikes while maintaining optimal operational safety. The pump also comes with an adjustable pressure cutoff as a standard feature, allowing users to tailor the pressure settings to specific application requirements. Additionally, it incorporates a boost pressure relief valve for added control over the hydraulic system's performance. The AA4VG90EP4D1/32R-NSF52F001DH-S allows for through-drive capabilities, meaning it can be used in tandem with further pumps up to the same nominal size without compromising efficiency or power. This feature makes it versatile for a range of complex hydraulic systems where multiple pumps are required. The pump's swashplate design is crafted for durability and consistent performance under demanding conditions. This Bosch Rexroth axial piston variable pump is suitable for applications requiring precise control of fluid power in a closed circuit configuration. Its robust design and advanced features ensure it delivers reliable and efficient operation across various applications without sacrificing performance.
