The Bosch Rexroth AA4VG71EZ1DMT1/32L-NSF52F041DH-S (R902094248) is an advanced axial piston variable pump that is engineered with precision for high-efficiency hydraulic applications. This pump features an integrated boost pump that ensures a consistent boost and pilot oil supply, which is essential for the smooth functioning of hydraulic systems. The innovative design allows the flow direction to change seamlessly when the swashplate moves through its neutral position, enhancing the operational flexibility of the pump. The AA4VG71EZ1DMT1/32L-NSF52F041DH-S is equipped with high-pressure relief valves that incorporate a boost function, providing an additional layer of protection against pressure spikes in the system. These relief valves are designed to be adjustable, allowing for standard pressure cutoff settings that can be tailored to specific application requirements. For applications requiring multiple hydraulic functions or stages, this model offers a through-drive capability, enabling further pumps of up to the same nominal size to be mounted in tandem. This feature allows for compact and efficient system designs without compromising on power or performance. Additionally, this Bosch Rexroth pump includes a boost pressure relief valve, ensuring reliable operation under various conditions and extending the lifespan of both the pump and the hydraulic system it serves. Its swashplate design is optimized for durability and performance, making it suitable for demanding applications where precision and reliability are paramount. Overall, the AA4VG71EZ1DMT1/32L-NSF52F041DH-S represents Bosch Rexroth's commitment to innovation in hydraulic technology, offering a versatile solution that meets rigorous industrial standards for efficiency and performance.
