Product Overview
The Rexroth A10VSO 18 DFR1/31R-VSC12N00-S4823 (Material Number: R902577101) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Featuring a swashplate design with a nominal displacement of 18 cm³/rev, this pump delivers precise, load-sensing flow control through its DFR1 control configuration, which combines pressure and flow (load-sensing) regulation with a pressure cut-off function. The A10VSO series is globally recognized for its robust construction, high power density, and exceptional volumetric efficiency, making it the benchmark choice for demanding continuous-duty applications in plastics machinery, metallurgy, and industrial automation.
