YUKEN A70-FR04HS-60366/60 Variable Displacement Piston Pump, Pressure & Load Sensing Proportional Control, 70.0 cm³/rev, Flange Mount, Right Hand Rotation, Keyed Shaft

The YUKEN A70-FR04HS Variable Displacement Piston Pump is engineered to deliver high performance and precise control in demanding industrial hydraulic applications. A key model within YUKEN's advanced A-Series, this pump integrates electro-hydraulic proportional pressure and load sensing control, offering superior operational stability, impressive energy efficiency, and reliable adaptability for a wide range of tasks.

Key Features:

• Advanced Electro-Hydraulic Proportional Pressure and Load Sensing Control (04HS): This pump features a sophisticated electro-hydraulic proportional control system for both pressure and load sensing. This capability allows the pump to dynamically adjust its output (flow and pressure) to precisely match the system's varying requirements by continuously monitoring both load and demand. The result is significant energy savings, reduced heat generation, and enhanced system responsiveness. The "HS" in the control denotation indicates a standard setting, with the 'H' typically referring to the pressure adjustment range (e.g., 2 - 20.6 MPa in the proportional control context as per YUKEN A-series documentation if an amplifier is integrated or implied by the model). The "60366/60" likely refers to specific internal design revisions or manufacturing codes, ensuring traceability and unique identification within the YUKEN product line.
• High Displacement for Demanding Applications: With a nominal displacement of 70.0 cm³/rev (cubic centimeters per revolution), this A70 model provides a robust, powerful, and highly efficient fluid delivery rate. This makes it ideally suited for heavy-duty hydraulic tasks that require substantial fluid volumes and precise flow management in various industrial settings.
• Robust Flange Mount and Right-Hand Rotation: The flange-mount (F) configuration ensures secure and stable integration into diverse hydraulic systems, designed for standard industrial connections. "Right Hand Rotation" (R) signifies the shaft rotation direction when viewed from the shaft end, ensuring compatibility with the drive motor.
• Optimized Performance and Noise Reduction: YUKEN A-series pumps are widely recognized for their high overall efficiency, which minimizes power losses and significantly reduces heat generation, contributing to cooler operation and extending the lifespan of hydraulic fluid and system components. Furthermore, their advanced design contributes to low noise emissions, creating a more comfortable and compliant working environment.
• Exceptional Durability and Reliability: Manufactured from high-quality, robust materials and subjected to precision engineering, coupled with rigorous quality control processes, this piston pump guarantees long-lasting and dependable performance even under the most challenging and continuous industrial operating conditions.
