The Bosch Rexroth AA4VG71HD3DT1/32R-NSF52F021D (R902232502) is a high-pressure pump designed for demanding applications in closed circuit systems. This robust pump features an integrated boost pump for both boost and pilot oil supply, ensuring reliable performance and efficiency. The flow direction within the pump changes smoothly as the swashplate moves through the neutral position, providing precise control over hydraulic functions. Equipped with high-pressure relief valves that include an integrated boost function, this model ensures safety and optimal operation within its pressure boundaries. Moreover, it comes standard with an adjustable pressure cutoff, allowing for customization according to specific application needs. The boost pressure relief valve further contributes to the system's safety by preventing overpressure conditions. The AA4VG71HD3DT1/32R-NSF52F021D is designed with a through-drive feature that permits the mounting of additional pumps up to the same nominal size directly to it, expanding its versatility and potential applications without requiring extra space. It is constructed using a swashplate design which is known for reliability and endurance under continuous use. With its nominal pressure rated at bar and maximum pressure reaching bar, this pump can handle rigorous use in various hydraulic systems. It is specifically configured in the SAE version tailored for the US market, ensuring compatibility with industry standards in North America. Overall, this Bosch Rexroth high-pressure pump stands out due to its integration of multiple functions into one unit, its adaptability through various control options, and its compliance with stringent performance criteria suitable for a wide range of industrial applications.
