YUKEN A56-F-R-04-H-A-K-32399/32 Variable Displacement Piston Pump, Pressure & Load Sensing Proportional Control, External Amplifier, 55.8 cm³/rev, Flange Mount, Clockwise Rotation, Keyed Shaft

The YUKEN A56-F-R-04-H-A-K Variable Displacement Piston Pump is a highly advanced hydraulic solution tailored for industrial applications that demand precise, adaptable, and efficient flow control. As a key model within YUKEN's esteemed A-Series, this pump integrates electro-hydraulic proportional pressure and load sensing control, explicitly designed for use with an external amplifier, ensuring superior performance, optimal energy efficiency, and exceptional system stability.

Key Features:

• Advanced Electro-Hydraulic Proportional Pressure and Load Sensing Control (04-H-A): This model is equipped with a sophisticated electro-hydraulic proportional control for both pressure and load sensing. This capability enables the pump to dynamically adjust its output to precisely match the system's varying requirements by continuously monitoring both pressure and load. This results in significant energy savings, reduced heat generation, and enhanced system responsiveness. The "H" in the control type denotes a specific pressure adjustment range (typically 2 - 20.6 MPa for A-series pumps like A56 with this type of proportional control), and the "A" explicitly indicates that an external amplifier is required to drive the proportional control, offering flexibility in system integration and fine-tuning. The "32399/32" likely refers to specific design or revision codes for the internal pump components, ensuring traceability and unique identification within the YUKEN product line.
• Optimal Performance with High Displacement: With a nominal displacement of 55.8 cm³/rev (cubic centimeters per revolution), this A56 model provides a robust, powerful, and highly efficient fluid delivery rate. This makes it ideally suited for demanding hydraulic tasks that require substantial fluid volumes and precise flow management in various industrial settings.
• Robust Construction and Mounting: The flange-mount (F) configuration ensures a secure and stable integration into diverse hydraulic systems. The pump is designed for standard clockwise rotation (R), and its keyed shaft (K) guarantees reliable power transmission from the drive motor, ensuring consistent operation.
• High 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.
• 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.
