The Bosch Rexroth AA4VG125DA1D2/32L-NSF52F011SH (R902055399) is a state-of-the-art axial piston variable pump designed for high-efficiency hydraulic applications. This particular model comes with an integrated boost pump that serves the dual purpose of providing boost and pilot oil supply, ensuring consistent and smooth operation across various conditions. The pump is engineered to allow for a seamless change in flow direction as the swashplate moves through the neutral position, enhancing the operational flexibility of the system it is integrated into. Equipped with high-pressure relief valves that include an integrated boost function, this pump guarantees safety and reliability by preventing over-pressurization within the hydraulic circuit. Additionally, it features an adjustable pressure cutoff as standard, which offers additional control over the operational parameters and protects against excessive pressure. The AA4VG125DA1D2/32L-NSF52F011SH model also includes a boost pressure relief valve for added system security. Its through-drive capability allows for the mounting of additional pumps up to the same nominal size, making it highly adaptable for complex hydraulic systems requiring multiple pumps. Designed with a swashplate mechanism, this Bosch Rexroth variable pump is known for its durability and responsiveness to control inputs. The variety of controls available with this unit makes it versatile for use in different applications where precise hydraulic fluid management is critical. Overall, this model exemplifies Bosch Rexroth's commitment to innovative design and robust performance in hydraulic technology.
