REXROTH A10VSO140LA7DS/32R-VPB12N00 / R902577438

Product Overview

The Rexroth A10VSO140LA7DS/32R-VPB12N00 (Material Number: R902577438) 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 140 cm³/rev and is configured with the LA7DS control variant, which provides load-sensing with pressure and flow compensation for precise, energy-efficient operation. As part of the A10VSO series, it is designed for open-circuit applications, delivering reliable high-pressure performance, excellent suction characteristics, and long service life in continuous-duty industrial environments. The pump serves as a central pressure and flow source in complex hydraulic power units, offering infinitely variable displacement to match system demand and reduce energy losses.
