The Bosch Rexroth AA4VG90HD3DT1/32R-NSF52F021D (R902205901) is a high-pressure axial piston pump designed for closed circuit applications. This particular model is tailored to meet the demands of the US market with its SAE version configuration. It features an integrated boost pump that ensures a consistent supply of boost and pilot oil, enhancing the efficiency and reliability of the system. The pump's flow direction transitions smoothly as the swashplate moves through its neutral position, which allows for precise control and operation. Equipped with high-pressure relief valves that include an integrated boost function, this unit guarantees safety and performance. Additionally, it comes standard with an adjustable pressure cutoff, providing users with flexibility and protection against system overloads. The inclusion of a boost pressure relief valve further contributes to its operational stability. Its through-drive capability is a significant advantage, permitting the attachment of additional pumps up to the same nominal size directly to the unit without requiring extra mounting space or complex configurations. This feature makes it an ideal solution for systems requiring multiple pump setups. The AA4VG90HD3DT1/32R-NSF52F021D is engineered using a swashplate design that is well-regarded for its durability and ability to handle high pressures effectively. With its robust construction, this Bosch Rexroth pump is capable of operating at a nominal pressure of up to bar while handling maximum pressures up to bar, making it suitable for a wide range of demanding hydraulic applications where precise fluid control and long service life are essential.
