Product Description
Yuken A Series High-Pressure Variable Displacement Piston Pump
Product Overview: The Yuken A Series variable axial piston pump is a high-performance benchmark in the industrial hydraulic sector, renowned for its superior efficiency, low noise, and exceptional reliability. Covering a comprehensive displacement range from the compact A10 to the heavy-duty A145, this series is widely utilized in injection molding machines, forging equipment, machine tools, and various industrial power units. Flagship models such as A56-F-R-04-H-K-32393, A90-FR04HAS-A-60366, and A145-FR04HS-60 support multiple control types (including pressure compensation and load sensing), making them the top choice for energy-saving hydraulic systems.
Key Technical Advantages:
Exceptional Volumetric Efficiency: Precision-ground piston and cylinder groups maintain peak output efficiency even at high operating pressures of 21 MPa.
Distinctive Low-Noise Design: Utilizing Yuken’s patented valve plate and damping technology, these pumps operate smoothly with noise levels significantly lower than competitors.
Sensitive Variable Control:
FR04/HAS Control Logic: The pressure compensator responds instantly; upon reaching the preset pressure, displacement is minimized to reduce reactive power loss and heat generation.
Reinforced Structure & Long Service Life: Bearings and rotating components are specifically engineered for high-frequency industrial cycles with strong resistance to fluid contamination.
100% Industrial Compatibility: Manufactured to strict SAE/ISO mounting standards with various shaft ends (keyed/splined) and porting options for seamless drop-in replacement.
