Product Overview

The Rexroth A10VO71DFR1/31R-VPC12N00M is a high-performance axial piston variable displacement pump engineered by Bosch Rexroth for open-circuit industrial and mobile hydraulic systems. Featuring a swashplate design with axial pistons, this pump delivers precise variable displacement control through its DFR1 (pressure and flow control) regulator, allowing it to maintain constant flow independent of load pressure up to the preset pressure compensator threshold. With a nominal displacement of 71 cm³/rev and belonging to the 31 series, it is built for demanding continuous duty in high-pressure hydraulic circuits, offering excellent power density, high volumetric efficiency, and long service life. The VPC12N00M configuration denotes a specific control variant and mounting interface, ensuring direct OEM-compatible integration into existing Rexroth drive systems.
