Product Overview

The Rexroth A4VG71EP4DT2/32L-NAF02F071SH is a high-pressure axial piston variable displacement pump from the renowned Bosch Rexroth A4VG series, engineered specifically for closed-circuit hydrostatic transmission systems. Utilizing a robust swashplate design with axial pistons, this pump delivers infinitely variable displacement and consistent high-pressure performance in both forward and reverse operating directions. The A4VG71 model features a nominal displacement of 71 cm³/rev and is widely deployed as the primary pump in mobile and industrial closed-loop drive systems, providing precise speed and torque control for hydraulic motors. Its integrated charge pump, high-pressure relief valves, and advanced displacement control options make it a complete, self-contained transmission solution for demanding heavy-duty applications.
