Product Description

A10VSO/A4VSO Series Axial Piston Variable Pump (R902481802 | A10VSO10DFR/52R-VPA14N00) Product Description
The A10VSO/A4VSO series axial piston variable pumps represent a benchmark in high-performance hydraulic solutions, engineered to meet the rigorous demands of industrial and mobile hydraulic systems. This product line includes core models such as A10VSO18, A10VSO28, A10VSO45, A10VSO100, A10VSO140, and the heavy-duty A4VSO180, alongside the precision-calibrated A10VSO10DFR/52R-VPA14N00 (part number R902481802) and its variant AA10VSO10DFR/52R-VPA14N00.
Designed with a swash plate variable displacement structure, these pumps deliver exceptional power density while maintaining a compact footprint—ideal for applications where space is limited but performance is non-negotiable.
Core Technical Advantages
Precision DFR Control SystemThe integrated DFR control mechanism enables automatic adjustment of displacement based on real-time system pressure and flow demands. This intelligent regulation minimizes energy loss, optimizes operational efficiency, and reduces overall running costs. The 52R-VPA14N00 control configuration further enhances stability, ensuring seamless integration with open-circuit hydraulic systems and consistent performance even under fluctuating load conditions.
High-Pressure DurabilityBuilt with premium wear-resistant materials—including hardened piston assemblies, precision-machined cylinder blocks, and corrosion-resistant valve plates—these pumps withstand maximum operating pressures suited for heavy-duty scenarios. This robust construction extends service life, cuts down maintenance frequency, and delivers reliable performance in harsh environments such as high temperatures and dusty work sites.
Versatile Model CompatibilityThe A10VSO/A4VSO series covers a wide range of flow rates, from the compact A10VSO18 to the high-capacity A4VSO180. This versatility allows customers to select the exact pump model that matches their system requirements, eliminating the need for costly custom modifications. As direct OEM replacements, these pumps ensure perfect interchangeability with existing setups, reducing downtime during equipment upgrades or part replacements.
