The Bosch Rexroth AA4VG125EP3D1/32L-NSF52F041DP (R902205570) is a high-pressure axial piston pump designed for closed circuit applications. This advanced pump features an integrated boost pump which serves the dual purpose of boost and pilot oil supply, ensuring consistent performance and reliability in operation. The flow direction within the pump transitions smoothly as the swashplate moves through its neutral position, enhancing the operational efficiency of hydraulic systems. Equipped with high-pressure relief valves that include an integrated boost function, this model ensures safety and precise control over the system pressure. Additionally, it comes standard with an adjustable pressure cutoff for added versatility in managing system pressures according to specific requirements. The AA4VG125EP3D1/32L-NSF52F041DP also includes a boost pressure relief valve to further enhance its functionality. Designed with a through-drive feature, this unit allows for the mounting of additional pumps up to the same nominal size, facilitating flexible configurations and expansion of hydraulic systems without compromising space or efficiency. The variety of controls available with this model makes it adaptable to a wide range of operational needs. The swashplate design inherent in this Bosch Rexroth pump is indicative of its robustness for high-pressure applications within closed circuits. It is specifically tailored to meet the demands of the US market with its SAE version compliance. With its nominal pressure rated at bar and maximum pressure at bar, this axial piston pump is engineered to deliver consistent performance even under demanding conditions. The AA4VG125EP3D1/32L-NSF52F041DP reflects Bosch Rexroth's commitment to quality and innovation in hydraulic system components.
