Yuken A Series Pump | A56, A70, A90, A145 | High Pressure Variable Piston Pump

Yuken A Series High-Pressure Axial Piston Variable Pump

Product Overview: The Yuken A series is a global benchmark in industrial hydraulics, renowned for its exceptional reliability, high volumetric efficiency, and outstanding quiet performance. This lineup spans mainstream displacements from 56cc (A56) to 145cc (A145). Flagship models such as the A70-FR02SD24-60 and A145-FR02SD24-60 are engineered for operations demanding continuous high pressure and precise flow modulation. By utilizing advanced control modes like pressure compensation and load sensing, the A series significantly minimizes heat generation and energy consumption, making it the ideal power source for injection molding machines, metal shears, and large-scale Hydraulic Power Units (HPU).

Key Technical Advantages:

• Superior Energy Efficiency: Optimized rotating group designs maintain peak efficiency under full load conditions, effectively minimizing power loss.

• Versatile Control Architectures:

  • FR01/FR02 Specs: Supports Pressure Compensator control, automatically reducing displacement once the target pressure is reached to maintain constant system pressure.

  • Solenoid Proportional Control (-SD24): Enables remote pressure and flow regulation via 24V DC signals, perfectly suited for highly automated industrial production lines.

• Industry-Leading Quiet Operation: Precision-balanced swashplate structures and valve plate technology reduce operational noise to a minimum, enhancing the factory workspace environment.

• Heavy-Duty Bearing System: Designed for high-cycle duty, ensuring an extended service life even under high-pressure environments ranging from 21 MPa to 28 MPa.

• Compact Design & High Power Density:

  • A90-FR01KS-60: The compact housing offers superior power density, ideal for integrated hydraulic systems with restricted installation space.
