Yuken A Series Pump | A70-F-R-04, A70-F-B-03 | 21MPa Variable Displacement Pump

Yuken A70 Series Industrial High-Pressure Axial Piston Variable Pump

Product Overview: The Yuken A series is a globally recognized flagship axial piston variable pump, renowned for its superior volumetric efficiency and exceptionally low noise levels. As a heavy-duty model within the series, the A70 (70cc) is specifically engineered to meet the high-pressure and high-flow demands of large-scale industrial machinery, with a rated pressure of 21 MPa. By integrating control modulations such as 04 (Pressure Compensator) or 03 (Remote Pressure Control), the A70 optimizes system energy consumption. For specific design numbers like 60366 and 6080, we offer OEM-grade precision replacements ideal for precision presses, plastic machinery, and heavy-duty Power Units (HPU).

Key Technical Advantages:

• Energy Savings & Rapid Dynamic Response: Featuring advanced control mechanisms, such as the A70-F-R-04-H, these pumps provide high-speed pressure compensation, de-stroking once the preset pressure is reached to minimize power loss.

• Whisper-Quiet Operation: Utilizing Yuken’s proprietary noise-reduction valve plate technology, the A70 maintains an exceptionally low decibel level even at a high displacement of 70cm³/rev under high pressure, enhancing the factory environment.

• Precise Match for Custom Design Numbers: Catering to specific industrial spare part requirements, we provide units for 60366 and 6080, ensuring mounting flanges and shaft configurations perfectly align with the original equipment specifications.

• Heavy-Duty Durability: The reinforced swashplate and rotating group design ensure peak volumetric efficiency under continuous high-pressure cycles, significantly reducing unplanned maintenance downtime.
