The Bosch Rexroth AA4VG90EP4D1/32L-NSF52F071DH (R902148775) is a high-pressure axial piston pump designed for closed circuit applications. This particular model is tailored for the US market, adhering to SAE standards, and boasts an impressive nominal pressure of up to 450 bar with a maximum pressure capacity reaching 500 bar. The pump features an integrated boost pump which serves to supply both boost and pilot oil, ensuring consistent performance and reliability even under demanding conditions. One of the key attributes of the AA4VG90EP4D1/32L-NSF52F071DH is its ability to smoothly transition flow direction as the swashplate moves through its neutral position, enhancing control and operational stability. It comes equipped with high-pressure relief valves that include an integrated boost function, providing an additional layer of protection against pressure spikes. Moreover, it features a boost pressure relief valve and an adjustable pressure cutoff as standard options, offering customizable control over the pump's performance parameters. This model also supports through-drive capabilities, allowing for the mounting of additional pumps up to the same nominal size directly onto it, which can be particularly beneficial in complex hydraulic systems requiring multiple pump configurations. The swashplate design is engineered for durability and efficiency in transferring rotary motion into linear motion within the hydraulic system. Overall, the AA4VG90EP4D1/32L-NSF52F071DH provides a robust solution for those in need of a reliable high-pressure pump capable of accommodating various control options and configurations in closed circuit applications.
