The Bosch Rexroth AA4VG71EZ1D1/32R-NSF52FXX1SH-S (R902119253) is a state-of-the-art axial piston variable pump with a swashplate design, engineered for high-pressure applications that require reliable hydraulic power. This pump features an integrated boost pump, which serves to supply both boost and pilot oil, ensuring consistent operation and efficiency. Its design allows for the flow direction to change smoothly as the swashplate moves through the neutral position, enhancing the control and responsiveness of the system. Equipped with high-pressure relief valves that include an integrated boost function, this Bosch Rexroth pump provides additional safety and operational stability. The adjustable pressure cutoff comes as a standard feature, allowing for precise control over the maximum pressure limit within the hydraulic system. Additionally, it includes a boost pressure relief valve which contributes to the protection of the system from pressure spikes. The AA4VG71EZ1D1/32R-NSF52FXX1SH-S model also offers versatility through its through-drive capability, which allows for the mounting of further pumps up to the same nominal size directly onto it. This enables users to expand their hydraulic systems without requiring additional space for extra pumps. A wide range of control options is available with this model, making it adaptable to various application requirements. This Bosch Rexroth variable pump is designed for those who need robust performance in demanding applications. Its advanced features ensure smooth operation under high-pressure conditions while offering flexibility in system design and adaptability to different control needs.
