Product Overview

The Rexroth A10VSO18DR+A10VSO10DR (Material Number R902488274) is a high-performance axial piston variable displacement double pump engineered for demanding industrial hydraulic systems. This tandem configuration integrates two independent swashplate-type axial piston pumps—a primary A10VSO18DR and a secondary A10VSO10DR—within a single compact housing, driven by a common shaft. Both pump stages feature DR (pressure-controlled) displacement regulation, automatically adjusting swashplate angle to maintain a constant preset system pressure while matching flow demand. This design eliminates the need for separate drive motors and reduces installation footprint, making it an ideal solution for multi-circuit hydraulic systems requiring precise pressure control and energy-efficient operation.
