Yuken A145 Series Pump | A145-FR04EH, A145-F-R-04 | 145cc Variable Piston Pump

Yuken A145 Series Variable Displacement Piston Pump

Product Overview: The Yuken A145 series is a high-efficiency variable axial piston pump engineered specifically for heavy-duty industrial hydraulic systems. Featuring a substantial displacement of 145.0 cm³/rev, this series meets the demanding requirements of large-scale machinery for both high pressure and high flow rates. Representative models, such as A145-FR04EH140RS-62-6060, integrate advanced pressure compensation and flow control mechanisms (FR04), ensuring superior energy efficiency under high-pressure conditions. With its compact swashplate design and high-strength cast iron housing, the A145 series is the premier choice for injection molding, medium-duty presses, and high-reliability industrial Hydraulic Power Units (HPUs).

Key Technical Advantages:

• High Displacement & Power Output: The 145cc specification offers excellent versatility in the industrial pump sector, delivering massive output power while significantly reducing no-load losses through variable displacement control.

• Precision Control Modalities (FR04/EH):

  • FR04 Pressure & Flow Control: Dynamically adjusts output based on load demand, automatically reducing flow upon reaching preset pressure to effectively control system heat.

  • EH Electro-Hydraulic Proportional Control: Supports integration with digital controllers for high-precision remote proportional adjustment of both flow and pressure.

• Superior Efficiency: Optimized swashplate and piston-shoe designs maintain volumetric efficiency above 95% at full load, drastically enhancing the overall energy utilization of the hydraulic system.

• Low Noise & Longevity: Acoustically optimized housing and high-precision bearings ensure exceptionally low operating noise even under continuous high-pressure operation, paired with excellent wear resistance.

• Flexible Mounting Configurations: Supports flange mounting (F) and various shaft end options to meet the integration needs of diverse industrial equipment.
