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

The YUKEN A56-F-R-04-H-K Variable Displacement Piston Pump represents a sophisticated solution for high-demand industrial hydraulic systems. As a prominent model within YUKEN's esteemed A-Series, this pump integrates electro-hydraulic proportional pressure and load sensing control, delivering superior performance, energy efficiency, and operational stability across a broad spectrum of challenging applications.

Key Features:

• Advanced Electro-Hydraulic Proportional Pressure and Load Sensing Control (04-H): This pump is equipped with advanced electro-hydraulic proportional control for both pressure and load sensing. This feature allows the pump to dynamically adjust its output to precisely match the system's 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 typically denotes a specific pressure adjustment range (e.g., for A-series pumps like A56 with this control, it's often 2 - 20.6 MPa, as per YUKEN documentation). 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), the A56 provides a powerful and highly efficient fluid delivery rate, making it ideally suited for demanding hydraulic tasks that require substantial fluid volumes and precise flow management.
• Robust Construction and Mounting: The flange-mount (F) configuration ensures secure and stable integration into various hydraulic systems. The pump is designed for standard clockwise rotation (R), and its keyed shaft (K) guarantees reliable power transmission from the drive motor.
• High Efficiency and Low Noise Operation: YUKEN A-series pumps are renowned for their high overall efficiency, which minimizes power losses and promotes cooler operation, thereby extending the lifespan of both hydraulic fluid and system components. Furthermore, their design contributes to low noise emissions, fostering a more comfortable and compliant working environment.
• Durability and Reliability: Manufactured from high-quality materials and subjected to precision engineering and rigorous quality control, this piston pump ensures long-lasting and dependable performance under the most challenging industrial operating conditions.
