The Bosch Rexroth AA4VG90EP4DMT1/32L-NSF52F011DH (R902123097) is an advanced axial piston variable pump that features a swashplate design for hydrostatic drives in closed circuits. This high-performance pump is equipped with an integrated boost pump, which ensures the supply of boost and pilot oil, essential for the efficient operation of hydraulic systems. The flow direction within the pump changes smoothly as the swashplate moves through its neutral position, ensuring seamless transitions in hydraulic flow. The AA4VG90EP4DMT1/32L-NSF52F011DH is designed with high-pressure relief valves that incorporate an integrated boost function, offering enhanced safety and reliability. These valves are complemented by an adjustable pressure cutoff as a standard feature, allowing for precise control over the operation parameters to match specific application requirements. Additionally, it includes a boost pressure relief valve to further manage system pressures effectively. This model also boasts a through-drive capability, which enables the mounting of additional pumps up to the same nominal size directly onto it. This feature provides flexibility and expandability in system design, allowing for complex hydraulic setups without compromising on space or efficiency. The versatility of controls available with this pump makes it suitable for a wide range of applications requiring exacting control and responsiveness. From mobile equipment to industrial machinery, this Bosch Rexroth axial piston variable pump represents a robust solution for those seeking reliable hydraulic power with precise control dynamics. Its construction is aimed at providing long service life and consistent performance under demanding conditions.
