Product Overview
The Rexroth AL A10V O 28 DR /31R-VSC12K01-S1743 (Material Number: R902074827) is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Featuring a swashplate design with axial pistons and a DR pressure-controlled displacement mechanism, this pump automatically adjusts its displacement to maintain a constant preset system pressure, delivering only the flow required by the load. With a nominal displacement of 28 cm³/rev, the A10V O series is renowned for its high power density, fast response to pressure changes, and long service life in demanding continuous-duty applications. The /31R series designation indicates a refined generation with optimized control response and improved volumetric efficiency, making it a direct-fit replacement for OEM installations worldwide.
