The Bosch Rexroth AA4VG90EP3D1/32L-NUF52F011SH (R902125886) is a high-performance axial piston variable pump designed for hydrostatic transmissions in closed circuits. This pump features an integrated boost pump that ensures the supply of boost and pilot oil is consistent and reliable. The flow direction of the pump can be changed smoothly as the swashplate moves through its neutral position, enhancing the operational flexibility of the pump. Equipped with high-pressure relief valves that incorporate a boost function, this model guarantees safety and efficiency in managing system pressures. Additionally, it comes standard with an adjustable pressure cutoff, providing users with control over maximum pressure settings to suit specific application requirements. The AA4VG90EP3D1/32L-NUF52F011SH also includes a boost pressure relief valve which contributes to the overall protection and longevity of the hydraulic system. Its through-drive capability is a significant advantage, allowing for the mounting of additional pumps up to the same nominal size directly onto this unit—this feature is particularly beneficial for systems requiring multiple pumps. Another key aspect of this Bosch Rexroth model is its wide range of control options, which cater to various operational demands and enhance user experience. The swashplate design underscores its efficiency and adaptability in applications requiring precise control over fluid displacement and flow rate. Overall, this axial piston variable pump is engineered for robust performance in demanding environments where reliability and versatility are critical. Its advanced features make it suitable for high-end hydraulic applications that require precise control and efficient power transmission.
