YUKEN A70-FR04HAS-60366/60 Variable Displacement Piston Pump, Proportional Electro-Hydraulic Load Sensing Control, External Amplifier Required, 70.0 cm³/rev, Flange Mount, Right Hand Rotation, Keyed Shaft

The YUKEN A70-FR04HAS Variable Displacement Piston Pump is a high-performance, electro-hydraulic proportional unit designed for precise control and energy efficiency in demanding industrial hydraulic systems. As a prominent model within YUKEN's advanced A-Series, this pump features a sophisticated proportional load sensing control system, specifically configured for operation with an external amplifier. This design ensures optimal system responsiveness and adaptability across a wide range of applications requiring precise flow and pressure management.

Key Features:

• Advanced Proportional Electro-Hydraulic Load Sensing Control (04HAS): This pump is equipped with state-of-the-art electro-hydraulic proportional control for both pressure and load sensing. This capability allows the pump to dynamically adjust its output to precisely match the system's requirements, ensuring energy savings and reduced heat generation. The "04" indicates it falls under the Proportional Electro-Hydraulic Load Sensing type (referencing page 5 of your PDF), and the "H" denotes a specific pressure adjustment range (typically 2 - 20.6 MPa in the proportional control context for A-series pumps). The crucial "A" clearly signifies that an external amplifier is required for operation, providing flexibility in integration and fine-tuning of the control system. The "S" typically indicates a standard setting or configuration within this control type. The "60366/60" refers to specific design or revision codes for the internal pump components, ensuring traceability and unique identification within the YUKEN product line.
• High Displacement for Robust Performance (70.0 cm³/rev): With a nominal geometric displacement of 70.0 cm³/rev (cubic centimeters per revolution) as indicated in the "A" Series Variable Displacement Piston Pumps table (page 25 of your PDF), this A70 model provides a powerful and highly efficient fluid delivery. 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. "Right Hand Rotation" (R) signifies the shaft rotation direction when viewed from the shaft end, which is standard for most industrial applications.
• High Operating Pressure Capabilities: According to the YUKEN A-Series specifications, A70 pumps with proportional electro-hydraulic load sensing can achieve a rated operating pressure of 25 MPa and an intermittent operating pressure of 28 MPa (referencing page 49 of your PDF). This robust pressure capability allows the pump to excel in challenging applications.
• Optimized Efficiency and Low Noise Operation: YUKEN A-series pumps are renowned for their high overall efficiency, which minimizes power losses and significantly reduces heat generation. This contributes to cooler operation, thereby extending the lifespan of both the hydraulic fluid and other system components. Furthermore, their advanced design contributes to low noise emissions, fostering 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, ensuring reduced downtime and maintenance.
