Yuken A3H Series Pump | A3H71-FR01KK | A3H100-FR01KK | High Pressure Piston Pump

Yuken A3H Series High-Pressure Variable Displacement Piston Pumps

Product Overview: The Yuken A3H series is a flagship product in the industrial hydraulic sector, renowned for its “High Pressure, High Efficiency, and Compact Design.” As a high-performance evolution of the A-series, the A3H is engineered specifically for rigorous industrial applications, covering core displacements such as 71cc (A3H71) and 100cc (A3H100). Featured models include the A3H71-FR01KK-10. The hallmark of this series is its ability to maintain a compact footprint while delivering a rated pressure of 31.5 MPa, making it the premier choice for metal stamping presses, heavy-duty machine tools, scrap balers, and large hydraulic power units (HPUs).

Key Technical Advantages:

• Extreme High-Pressure Capability: Rated for continuous operation at 31.5 MPa (315 Bar) with peak capabilities up to 40 MPa (400 Bar), ensuring robust performance under maximum loads.

• Superior Self-Priming Speed: Fluid-dynamically optimized internals significantly enhance self-priming capabilities, allowing for higher operational speeds without requiring a charge pump.

• Excellent Volumetric Efficiency: The optimized 9-piston architecture minimizes internal leakage, maintaining a volumetric efficiency of over 95% even at pressures exceeding 30 MPa.

• Responsive Control Options: Equipped with FR01 (Pressure Compensator Control) and other regulators, the pump reacts instantly to load changes, reducing heat generation and maximizing energy savings.

• Compact & Low-Noise Design: Despite its immense power output, the A3H series features a sound-dampening housing that drastically reduces mechanical noise during high-pressure cycles.
