Yuken A3HG71 & A3HG145 Pump | A3HG71-FR01KK-E1D-10 | High Pressure Variable Piston Pump

Yuken A3HG Series High-Pressure Variable Displacement Piston Pump

Product Overview: The Yuken A3HG series is a high-performance axial piston variable displacement pump engineered specifically for extreme high-pressure industrial applications. As a reinforced version of the A3H line, the A3HG series sustains continuous operating pressures up to 31.5 MPa, showcasing exceptional power density. Featured models like the A3HG71-FR01KK-E1D-10 and A3HG145-FR01KK-E1D integrate advanced pressure compensation (01) and electronic regulation. This series is widely utilized in large hydraulic presses, continuous casting equipment in steel mills, injection molding, and heavy-duty power units requiring long-term high-pressure output.

Key Technical Advantages:

• Ultra-High Pressure Capability: Rated for 31.5 MPa continuous duty with peak capabilities reaching 35 MPa, ensuring system stability during heavy forging operations.

• Efficient Variable Control:

  • FR01 Control: Precision pressure compensation mechanism that automatically reduces displacement upon reaching the setpoint, maximizing energy savings.

  • E1D Configuration: Optimized response times ensuring agile and accurate hydraulic system movements.

• Heavy-Duty Durability: Features reinforced swashplate and piston assemblies, significantly enhancing contamination resistance and mechanical efficiency while extending maintenance intervals.

• Superior Low-Noise Operation: Utilizing patented pulsation suppression technology, operational noise remains remarkably low even under high-pressure conditions compared to competitors.

• 100% Industrial OEM Compatibility: Manufactured to strict Yuken official standards (e.g., Series 10 design), ensuring shafts, flanges, and porting align perfectly for “drop-in” replacement.
