The Bosch Rexroth AA4VG90EP4DMT1/32L-NSF52F901DP (R902249905) is a high-pressure axial piston pump designed for closed circuit applications, particularly tailored for the US market with its SAE version. This advanced pump features an integrated boost pump which serves both the boost and pilot oil supply, ensuring reliable performance and efficiency. The flow direction of the pump can be smoothly altered as the swashplate transitions through its neutral position, enhancing the operational control of the system. Equipped with high-pressure relief valves that include an integrated boost function, this model also boasts an adjustable pressure cutoff as a standard feature. The presence of a boost pressure relief valve further contributes to its safety and functionality. Additionally, it offers a through-drive capability which allows for the mounting of additional pumps up to the same nominal size, expanding its adaptability in complex hydraulic systems. The swashplate design of this Bosch Rexroth pump facilitates consistent and precise control over hydraulic fluid flow, making it suitable for demanding applications that require meticulous management of fluid dynamics under high-pressure conditions. With a size that accommodates substantial flow rates and engineered to operate efficiently within nominal pressure bar ranges and maximum pressure bar thresholds, this pump is designed to meet rigorous operational standards while maintaining stability and longevity in challenging environments.
