The Bosch Rexroth AA4VG71EP4DM1/32R-NSF52F011PT (R902131320) is a high-pressure pump designed for closed-circuit applications, exemplifying cutting-edge hydraulic engineering. This model features an integrated boost pump which serves to provide both boost and pilot oil supply, ensuring consistent and reliable operation. The smooth flow direction transition when the swashplate moves through the neutral position highlights the pump's precision control capabilities. Equipped with high-pressure relief valves that include an integrated boost function, this pump ensures safety and optimal performance under various conditions. Moreover, it comes standard with an adjustable pressure cutoff, offering additional operational control. The presence of a boost pressure relief valve further underscores its robust safety features. For enhanced versatility, this model boasts a through-drive design allowing for the mounting of additional pumps up to the same nominal size, thereby enabling customization to specific system requirements. Its swashplate design is tailored for efficiency and reliability in demanding environments. With a size that caters to substantial hydraulic requirements, this pump maintains a nominal pressure of bar and can handle maximum pressure peaks with exceptional ease. It also conforms to SAE standards specifically for the US market, ensuring compliance with regional specifications. In summary, the Bosch Rexroth AA4VG71EP4DM1/32R-NSF52F011PT is a sophisticated component suitable for high-demand hydraulic systems where consistent performance and adaptability are paramount.
