Product Overview
The Rexroth A10VSO100 DFR /31R-VPA12N00 (Material Number: R910920969) is a high-performance axial piston variable displacement pump engineered for demanding industrial and mobile hydraulic systems. Featuring a swashplate design, this pump delivers reliable performance in open-circuit applications with a nominal pressure rating of 280 bar and a peak pressure capability of 350 bar. The DFR control variant combines pressure and flow control (DFR = Pressure/Flow Controller with mechanical torque limitation), enabling precise adaptation to system demands while optimizing energy consumption. With a displacement of 100 cm³/rev, this pump is ideal for continuous duty cycles requiring high efficiency and precise control.
