The Bosch Rexroth AA4VG71EP4DM1/32R-NSF52F041PT (R902112174) is a high-pressure axial piston pump designed for closed circuit applications. This particular model features an integrated boost pump that ensures a reliable supply of boost and pilot oil, which is essential for the smooth operation of hydraulic systems. The pump's flow direction changes seamlessly as the swashplate moves through the neutral position, enhancing the machine's efficiency and responsiveness. Equipped with high-pressure relief valves that include an integrated boost function, this Bosch Rexroth pump provides added safety and control. The pressure cutoff is adjustable as a standard feature, allowing for customization according to specific system requirements. Additionally, it includes a boost pressure relief valve to further safeguard the hydraulic circuit. This model offers versatility through its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly to its housing. This can be particularly useful in complex hydraulic systems requiring multiple pump configurations. The AA4VG71EP4DM1/32R-NSF52F041PT is constructed with a robust swashplate design that is well-suited for demanding applications requiring consistent and reliable high-pressure performance. It is specifically configured in an SAE version tailored for the US market, ensuring compatibility with standard American equipment and regulations. With its size and nominal pressure rating at bar level, alongside a maximum pressure capacity also measured in bars, this Bosch Rexroth axial piston pump represents a dependable solution for various high-pressure applications within closed hydraulic circuits.
