The Bosch Rexroth AA4VG90EP3D1/32R-NSF52F071BP (R902148765) is a highly efficient axial piston variable pump designed for hydrostatic drives in an open circuit. This model is distinguished by its integrated boost pump, which ensures a reliable boost and pilot oil supply, enhancing the overall performance of the hydraulic system. It features a swashplate design that allows for smooth changes in flow direction as the swashplate moves through the neutral position, offering precise control over the hydraulic drive. Equipped with high-pressure relief valves that incorporate a boost function, this pump maintains optimal operation by protecting against excessive pressure build-up. Additionally, it comes with an adjustable pressure cutoff as a standard feature, allowing for customization according to specific application requirements. The inclusion of a boost pressure relief valve further contributes to its safety and reliability. This particular model also provides versatility through its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly onto it. This feature is particularly useful for systems requiring multiple pumps, thereby saving space and simplifying installation. The Bosch Rexroth AA4VG90EP3D1/32R-NSF52F071BP is designed to offer robust performance and adaptability with its wide range of controls, meeting various operational demands. Its advanced engineering is suitable for applications that require precise fluid handling and high dependability in their hydraulic components.
