The Bosch Rexroth AA4VG90EP4DMT1/32L-NSF52F001DH (R902123098) is a high-pressure axial piston pump designed specifically for applications in closed circuits. This pump features an integrated boost pump that ensures a consistent supply of boost and pilot oil, enhancing the overall efficiency and reliability of the hydraulic system. The swashplate mechanism within this model allows for smooth changes in flow direction as it moves through the neutral position, thereby ensuring precise control over the hydraulic functions. Equipped with high-pressure relief valves that include an integrated boost function, this pump maintains optimal performance even under varying pressure conditions. It also comes with an adjustable pressure cutoff as a standard feature, providing additional safety and control over the operation of the hydraulic system. The boost pressure relief valve further contributes to the stable operation of the unit. The AA4VG90EP4DMT1/32L-NSF52F001DH is designed for versatility, featuring a through-drive capability which permits the mounting of additional pumps up to the same nominal size directly onto it. This allows for a compact and efficient multi-pump configuration. It is built to handle a nominal pressure of up to 450 bar and can withstand maximum pressures up to 500 bar, ensuring robust performance in demanding applications. The SAE version of this pump is tailored to meet the requirements of the US market, adhering to industry standards for compatibility and integration into various hydraulic systems. With its swashplate design, this Bosch Rexroth axial piston pump stands out as a durable and efficient solution for mobile and industrial applications requiring high-pressure capabilities within closed circuit systems.
