Product Overview

The HUADE HD-A10VSO100DFR1/31R-VSC12-K04 is a high-performance axial piston variable displacement pump engineered for demanding industrial hydraulic systems. Manufactured by HUADE (Beijing Huade Hydraulic), this pump belongs to the A10VSO series, which is widely recognized as an industry-standard swashplate-type axial piston pump platform. The model designation “A10VSO100” indicates a nominal displacement of 100 cm³/rev, while the “DFR1” control suffix denotes a pressure and flow (load-sensing) combined control with a pressure compensator override. The “31R” designates the series 31 revision with clockwise rotation, and “VSC12-K04” specifies the mounting and shaft configuration. This pump operates on the swashplate principle, where the angle of the swashplate determines the piston stroke and thus the displacement. It is designed to deliver precise, energy-efficient flow control in closed-loop or open-loop industrial circuits, making it a critical component in systems requiring variable flow and pressure compensation.

Engineering Features & Advantages

Precision Swashplate Performance: The axial piston design with variable swashplate angle enables infinitely variable displacement, delivering precise flow matching to system demand and reducing energy losses through load-sensing control.
DFR1 Load-Sensing Control: The integrated pressure and flow controller maintains constant flow independent of load pressure, while the pressure compensator limits maximum system pressure, ensuring efficient operation and protection against overload.
Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust bearings, hardened piston/cylinder interfaces, and high-quality sealing for long service life.
Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM HUADE A10VSO series pumps, ensuring drop-in replacement without system modification.
High Power Density: Compact design delivers high pressure and flow from a small envelope, ideal for space-constrained machinery.
