Product Features
  • Electro-Hydraulic Dual-Swashplate Variable & Load-Sensing Power Matching: Features tandem/parallel variable-displacement axial piston pumps integrated with high-precision electro-hydraulic proportional valves. It dynamically adjusts the swashplate angle in milliseconds based on operator input and real-time load resistance, delivering flow-on-demand to optimize hydraulic horsepower efficiency and cut fuel consumption. 
  • Ultra-High Operating Peak Pressure & Heavy-Duty Tribological Pair: Encased in a heavy-duty cast-steel housing rated for high working pressures up to 35–38 MPa (350+ bar). Internal components including cylinder blocks, pistons, and valve plates feature advanced nitriding and wear-resistant coatings, ensuring high volumetric efficiency and anti-cavitation durability under harsh mining conditions. 
  • Modular Dual-Pump Flow Merging & System-Level Integration: Integrated with flow-merging valve manifolds and electronic pressure sensor ports directly on the pump head, allowing automatic dual-pump flow consolidation during high-load lifting or rapid compound operations. Designed with standard SAE high-pressure flanges and splined shafts for streamlined engine-bay integration and simplified maintenance. 
Friendly Reminder: Please ensure this part number matches your machine model and serial number. We strongly recommend checking with the official parts catalog or providing your machine serial number before purchase to avoid ordering the wrong part.
