Yuken A3H & A3HG Pump | A3H16, A3H37, A3H100-FR01KK | High Pressure Pump for Injection Machine

Yuken A3H & A3HG Series High-Pressure Piston Pump for Injection Machines

Product Overview: The Yuken A3H series and its reinforced A3HG series are the power cornerstones of hydraulic systems in injection molding machines worldwide. Engineered specifically to meet the rigorous demands of injection processes—including high pressure, rapid response, and long-term stability—this series is a global industry leader. Featured models such as the A3H16-FR01KK-10, A3H37-FR01KK-10, and A3H100-FR01KK-10 integrate advanced pressure compensator (FR01) controls. This ensures high clamping forces while significantly reducing energy consumption during the pressure-holding phase. Its high power-to-weight ratio makes it the ideal choice for high-performance injection and die-casting machinery.

Key Technical Advantages:

• Optimized for Injection Molding: Internally reinforced for the unique cycling characteristics of injection machines, capable of withstanding frequent pressure switching and high-speed operation.

• Extreme Pressure Capability: Rated for 31.5 MPa (4500 PSI) continuous duty with peak support up to 35 MPa (5000 PSI), ensuring robust power output during the injection stroke.

• Precision FR01 Control: The highly sensitive pressure compensator mechanism instantaneously de-strokes upon reaching the setpoint, effectively suppressing oil temperature rise and saving energy.

• Superior Volumetric Efficiency: Maintains exceptional volumetric efficiency even under high-pressure conditions, minimizing internal leakage and improving machine cycle accuracy.

• 100% OEM Standard Compatibility: Manufactured to strict Yuken Series 10 standards, ensuring flanges, shafts, and porting align perfectly for a seamless “drop-in” replacement on original equipment.
