Yuken A Series Pump | A22, A37, A56, A145 | 21MPa Variable Piston Pump

Yuken A Series Industrial High-Pressure Axial Piston Variable Pump

Product Overview: The Yuken A series is globally recognized as the premier flagship for high-efficiency, low-noise axial piston variable pumps in the industrial sector. Spanning a full displacement range from the compact A22 (22cc) to the heavy-duty A145 (145cc), this series is engineered to excel in demanding manufacturing environments. Utilizing advanced pressure compensator controls (e.g., Type 01), A series pumps automatically modulate flow based on system pressure, drastically reducing energy consumption and oil temperature rise during pressure-holding phases. Models like A22-F-R-01 and A37-F-R-01 maintain peak performance even under 21 MPa high-pressure conditions.

Key Technical Advantages:

• Ultra-Low Noise Operation: Featuring Yuken’s proprietary noise-reduction technology, even large models (e.g., A90, A145) maintain exceptionally low decibel levels under high pressure, significantly enhancing the workplace environment.

• Superior Energy Efficiency (Type 01 Control): Models such as A22-F-R-01-C and A37-F-R-01-B automatically de-stroke to minimum displacement once preset pressure is reached, maintaining pressure while minimizing power loss.

• Heavy-Duty Durability (K-32 Design): Units featuring the K-32 design code represent Yuken’s latest technical enhancements, offering increased bearing capacity and seal reliability for an extended service life under 24/7 operational cycles.

• Comprehensive Displacement Range: Available in sizes A10, A16, A22, A37, A45, A56, A70, A80, A90, A100, A125, and A145, ensuring a precise match for applications ranging from precision machine tools to heavy-duty extrusion presses.
