The Bosch Rexroth AA4VG125EP3D1/32R-NSF52F691BP (R902148481) is a high-pressure axial piston pump designed for closed circuit applications. This particular model features an integrated boost pump that ensures the provision of boost and pilot oil supply, which is critical for consistent and reliable operation. The pump's design allows for smooth flow direction changes as the swashplate moves through its neutral position, enhancing the operational finesse of hydraulic systems. This Bosch Rexroth pump comes equipped with high-pressure relief valves that include an integrated boost function, providing additional safety and performance assurance. It also boasts an adjustable pressure cutoff as a standard feature, allowing users to tailor the pump's operation to specific application requirements. The inclusion of a boost pressure relief valve further enhances its functionality. The AA4VG125EP3D1/32R-NSF52F691BP model offers versatility with its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly onto it. This feature makes it ideal for systems requiring multiple pump configurations without compromising space or complexity. With its robust swashplate design, this Bosch Rexroth high-pressure pump is engineered to withstand demanding conditions while maintaining efficiency and reliability. Its specifications include a nominal pressure bar rating and a maximum pressure bar capacity, signifying its suitability for high-pressure applications within closed circuits. Finally, this model has been tailored specifically for the US market with an SAE version configuration, ensuring compatibility with a broad range of equipment and compliance with industry standards in the United States. The AA4VG125EP3D1/32R-NSF52F691BP represents a sophisticated hydraulic solution that delivers both performance and adaptability for advanced hydraulic systems.
