Product Overview
The Rexroth A10VSO28DFR/31R-PSC62K01 (Material Number: R902427961) is a high-performance variable displacement axial piston pump engineered by Bosch Rexroth for open-circuit industrial hydraulic systems. Featuring a swashplate design with axial pistons, this pump delivers precise, infinitely variable displacement control through its DFR (pressure and flow control) regulator. 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. With a nominal displacement of 28 cm³/rev and a nominal pressure rating of 280 bar (peak 350 bar), this pump provides reliable, energy-efficient flow control across a wide range of industrial machinery and mobile hydraulic systems.

Engineering Features & Advantages
- Precision Swashplate Performance: The axial piston swashplate design enables infinitely variable displacement, delivering exact flow matching to system demand and significantly reducing energy consumption and heat generation.
- DFR Control Versatility: Integrated pressure and flow (load-sensing) control with pressure cut-off ensures the pump only delivers the flow required by the load, optimizing system efficiency and preventing overload conditions.
- High Power Density: Compact footprint with a high pressure-to-size ratio, allowing installation in space-constrained machinery without compromising hydraulic performance.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust bearings, hardened piston shoes, and a durable valve plate for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification to existing hydraulic circuits.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
