The Bosch Rexroth AA4VG90HD3D1/32L-NUF52F001D (R902122952) is a highly sophisticated axial piston variable pump that is engineered for high-performance hydraulic systems. This pump features an integrated boost pump which serves the dual purpose of boosting and providing pilot oil supply, ensuring reliable operation even under demanding conditions. The design allows for a smooth flow direction change when the swashplate is transitioned through the neutral position, which enhances the operational finesse of the equipment it's paired with. The AA4VG90HD3D1/32L-NUF52F001D is equipped with high-pressure relief valves that come with an integrated boost function, elevating its safety profile by protecting against pressure spikes within the hydraulic circuit. An additional key feature includes an adjustable pressure cutoff as standard, which provides users with control over maximum system pressure to match specific application requirements. Moreover, this model comes with a boost pressure relief valve and offers through drive capability. This allows for the mounting of further pumps up to the same nominal size directly onto this unit, facilitating compact and versatile system designs. Its large variety of controls enables customization and adaptability to a wide range of operational scenarios. Crafted with a robust swashplate design, this Bosch Rexroth variable pump stands out for its durability and consistent performance in various applications where precise hydraulic fluid control is critical. It's designed to meet the rigorous demands of industrial environments while maintaining efficiency and reliability.
