The Bosch Rexroth AA4VG90HD3D1/32L-NSF52F071F (R902205988) is a high-pressure axial piston pump designed for closed circuit applications. This particular model features an integrated boost pump that provides both boost and pilot oil supply, ensuring a reliable and consistent performance. The pump is engineered to allow smooth directional changes of flow when the swashplate moves through the neutral position, enhancing operational control and efficiency. Equipped with high-pressure relief valves that include an integrated boost function, this pump maintains optimal safety by preventing overpressure scenarios. It also comes standard with an adjustable pressure cutoff feature, providing additional protection and energy savings by avoiding unnecessary power consumption when reaching the set pressure limit. For further system customization and expansion, the AA4VG90HD3D1/32L-NSF52F071F offers a through-drive option which allows for the mounting of additional pumps up to the same nominal size directly to it. This capability enables users to adapt their hydraulic systems to various requirements without needing separate drive mechanisms. The swashplate design of this model contributes to its robustness and durability in demanding applications. Additionally, it includes a boost pressure relief valve which ensures consistent system performance even under varying load conditions. This SAE version is tailored for the US market, adhering to specific standards and regulations required in this region. With its nominal pressure rating at bar and a maximum pressure bar rating, it can handle rigorous operational demands found in various applications requiring precise hydraulic fluid control. The Bosch Rexroth AA4VG90HD3D1/32L-NSF52F071F stands out as an efficient solution for high-pressure applications in closed hydraulic circuits where reliability and adaptability are critical.
