The Bosch Rexroth AA4VG40HWDL1/32R-NSC53F025D-S (R902079889) is a high-pressure axial piston pump designed for closed circuit applications. This robust pump features an integrated boost pump, which ensures both boost and pilot oil supply, enhancing the reliability and efficiency of the hydraulic system. The design allows for smooth flow direction changes as the swashplate moves through the neutral position, providing precise control and operational stability. Built with high-pressure relief valves that incorporate a boost function, this model ensures safety and optimal performance under varying conditions. The pressure cutoff is adjustable as standard, allowing for customization according to specific application needs. Additionally, it includes a boost pressure relief valve which contributes to the overall protection and longevity of the pump. The AA4VG40HWDL1/32R-NSC53F025D-S is also equipped with a through-drive feature, enabling the mounting of additional pumps up to the same nominal size, expanding its versatility in multi-pump systems. Its swashplate design is engineered for heavy-duty operations, maintaining high efficiency even under demanding circumstances. With its nominal pressure rated at bar and maximum pressure at bar, this SAE version is tailored for the US market. It meets stringent standards required by various hydraulic applications by offering reliability and adaptability. The Bosch Rexroth AA4VG40HWDL1/32R-NSC53F025D-S pump stands out due to its combination of advanced features that ensure performance and longevity in closed circuit systems.
