Product Overview
The Rexroth A4VSO 40 DR /10R-P PB13N00 (Material Number: R902418820) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for demanding industrial hydraulic systems. Operating on the proven swashplate principle, this pump features a nominal displacement of 40 cm³/rev and is configured with a DR pressure-controlled (pressure compensator) regulator, enabling precise, load-dependent flow adjustment that maintains constant system pressure while minimizing energy consumption and heat generation. As part of the A4VSO series, it is designed for open-circuit operation with a through-drive capability, making it a cornerstone component for high-pressure, high-reliability hydraulic power units in stationary and heavy-duty industrial machinery.
