The Rexroth R902477807, model A4VG125DA2D3/32R-NAF02F001S-S, is a high-pressure axial piston variable pump designed for closed-circuit hydrostatic transmissions. Engineered for reliability and performance, this pump provides a flow that is directly proportional to the drive speed and displacement. The swashplate design allows for infinitely variable flow by adjusting its angle, enabling smooth reversal of flow direction. It is widely used in demanding mobile and industrial applications requiring precise control and high power density. This model features a DA2 hydraulic control system that is speed-related and includes a pressure cut-off for enhanced system protection.
