The Bosch Rexroth AA4VG125EP4DT1/32R-NSF52K041EH-S (R902128100) is a state-of-the-art high-pressure pump designed for closed circuit applications. This particular model is tailored for the US market with an SAE version, ensuring compatibility and ease of integration. The pump features an integrated boost pump which is essential for boost and pilot oil supply, enhancing the efficiency and reliability of the hydraulic system it serves. The flow direction of this pump changes smoothly as the swashplate transitions through the neutral position, which allows for precise control and operation. Equipped with high-pressure relief valves that include an integrated boost function, this model guarantees safety and performance under various conditions. Additionally, it comes standard with an adjustable pressure cutoff, providing additional customization according to specific application needs. The boost pressure relief valve is another critical feature that contributes to the overall stability and longevity of the pump. The AA4VG125EP4DT1/32R-NSF52K041EH-S offers a through-drive capability, which permits the mounting of additional pumps up to the same nominal size, thus offering versatility in system design and expansion possibilities without requiring extensive modifications. This feature makes it ideal for complex hydraulic systems where multiple pumps are necessary. Designed with a robust swashplate mechanism, this high-pressure pump can handle nominal pressures bar and maximum pressures bar effectively, making it suitable for demanding environments where consistent performance is essential. Its wide range of controls further enhances its adaptability to specific tasks or operational requirements. In summary, Bosch Rexroth's AA4VG125EP4DT1/32R-NSF52K041EH-S is engineered to deliver reliable performance in closed circuit hydraulic systems where high pressure and precise control are paramount. Its integrated features and capabilities make it a versatile solution for advanced hydraulic applications.
