The Bosch Rexroth AA4VG125HD3DT1/32R-NSF52F021D (R902125374) is a state-of-the-art axial piston variable pump that features an integrated boost pump for both boost and pilot oil supply, ensuring consistent and efficient operation. The design allows for smooth flow direction changes as the swashplate moves through the neutral position, enhancing the control and responsiveness of the system. This model is equipped with high-pressure relief valves that include an integrated boost function, providing additional safety and performance reliability. The pump also comes with an adjustable pressure cutoff as a standard feature, allowing for precise control over the maximum system pressure to protect against overloads. An added benefit is the boost pressure relief valve, which contributes to the overall stability and longevity of the hydraulic system. The AA4VG125HD3DT1/32R-NSF52F021D offers versatility through its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly onto it, thus saving space and reducing complexity in multi-pump configurations. Designed with robustness in mind, this unit is based on a swashplate design that is well-regarded for its durability and reliability in demanding applications. The large variety of controls available with this model ensures that it can be tailored to meet specific requirements across a range of applications, making it a flexible solution for many hydraulic systems. With its advanced features and capabilities, the Bosch Rexroth AA4VG125HD3DT1/32R-NSF52F021D represents a sophisticated hydraulic component engineered to deliver high performance and reliability.
