Yuken A Series Variable Piston Pump | A70, A90, A145 | A70-FR04HAS-A-60366 with ERG-01-1113 Valve

Yuken A Series Variable Piston Pump (A70 / A90 / A145)

Product Overview: The Yuken A Series Variable Displacement Piston Pump is a cornerstone of heavy-duty hydraulic systems, renowned for its exceptional low-noise characteristics and high volumetric efficiency. Engineered for injection molding machines, metal forming presses, and large-scale industrial power units, it delivers stable operating pressures up to 35 MPa. Specifically, models featuring the FR04 pressure and flow compensation control, such as the A70-FR04HAS-A-60366, integrated with the ERG-01-1113 proportional electro-hydraulic pilot relief valve, allow for intelligent remote regulation of system pressure and flow.

Key Technical Advantages:

• Advanced FR04 Control Logic: Features high-sensitivity pressure and flow compensation. The system adjusts dynamically based on load demand, significantly reducing bypass loss and heat generation.

• Proportional Integration: Equipped with the ERG-01-1113 pilot valve, the pump unit enables remote electronic signaling, ensuring smooth pressure transitions and minimizing hydraulic shock.

• Ultra-Low Noise Design: Utilizing an acoustically optimized pump body and specialized port plate design, the A series maintains noise levels well below industry standards even under full load.

• Heavy-Duty Durability: For high-displacement specs like A70, A90, and A145, reinforced bearings and specially coated pistons ensure a long maintenance-free service life under continuous high-pressure cycles.

Specific Models & Technical Parameters: This range includes core models: A70-FR04HAS-A-60366, A90-FR04, A145-FR04, and control valve ERG-01-1113. Key specifications: Displacement from 70 cm³/rev to 145 cm³/rev, rated pressure of 31.5 MPa, peak pressure up to 35 MPa, FR04 control logic, and support for electro-hydraulic proportional pilot regulation.
