Product details
Yuken A3H145-FR01KK-10 Hydraulic Piston Pump
I. Product Overview
The Yuken A3H145-FR01KK-10 is a high-pressure variable displacement piston pump manufactured by YUKEN (Japan), belonging to the A3H series. Featuring a swashplate design, this pump offers high pressure, large flow capacity, low noise, and low vibration. It is widely applied in industrial fields requiring high-pressure, large-flow, and flow-adjustable hydraulic systems, such as injection molding machines, die-casting machines, hydraulic presses, construction machinery, and marine machinery.

II. Key Specifications
1. Rated Pressure: Up to35 MPa(some sources mention 28 MPa, which may vary by model or application).
2. Displacement Range: 16–180 cm³/rev (specific displacement varies by model; the A3H145-FR01KK-10 offers a larger displacement for high-flow requirements).
3. Speed Range: Multiple speed options are typically available to meet application demands.
4. Drive Method: Electric drive.
5. Control Methods:
• Pressure Compensation Control: Automatically adjusts flow based on load pressure to maintain stable system pressure.
• Constant Power (Torque) Control: Limits output flow according to input power to prevent motor overload.
• Load-Sensing Control: Adjusts flow in real-time based on load demand for optimized energy efficiency.
6. Materials & Structure:
• The pump body is made of high-strength materials such as cast aluminum, offering lightweight and corrosion resistance.
• Precision-matched pistons and cylinders ensure excellent sealing performance and minimal leakage.
• A single-stage closed impeller design provides a compact structure and high efficiency.

III. Performance Characteristics
1. High Efficiency: Volumetric efficiency exceeds 95%, and mechanical efficiency exceeds 90%, minimizing energy loss.
2. Low Noise & Vibration: Optimized design reduces operational noise and vibration, making it suitable for environments with strict noise requirements.
3. Long Service Life: High-strength materials and precision manufacturing ensure wear resistance and corrosion resistance, extending operational lifespan.
4. Easy Flow Adjustment: Supports multiple control methods for flexible adjustment of output flow and pressure according to actual needs.
5. Energy-Saving & Environmentally Friendly: Intelligent control reduces无效能耗 (inefficient energy consumption), lowering operating costs.

IV. Applications
1. Injection Molding Machines: Provides stable high-pressure hydraulic power to ensure precision and efficiency in the injection molding process.
2. Die-Casting Machines: Maintains stable system pressure during high-pressure casting processes, improving product quality.
3. Hydraulic Presses: Offers large-flow hydraulic support for stamping, forging, and other processes, enhancing production capacity.
4. Construction Machinery: Operates reliably under heavy-load and high-pressure conditions in excavators, loaders, and other equipment.
5. Marine Machinery: Supplies reliable hydraulic power for ship steering gear, anchor winches, and mooring winches, ensuring safe navigation.
6. Metallurgical Machinery: Achieves high-pressure hydraulic control in rolling mills, steel furnaces, and other equipment, improving production efficiency.

V. Selection & Configuration Recommendations
1. Selection Based on Pressure Requirements: If system pressure requirements exceed 28 MPa, prioritize models with a rated pressure of 35 MPa.
2. Selection Based on Flow Requirements: The A3H145-FR01KK-10 offers a large displacement, suitable for high-flow applications. For lower flow demands, consider models like the A3H16-FR01KK-10.
3. Selection Based on Control Method:
• For stable pressure, choose pressure compensation control models.
• To prevent motor overload, select constant power control models.
• For optimized energy efficiency, opt for load-sensing control models.
4. Selection Based on Installation Space: For limited installation space, choose compact models or flange-mounted versions (e.g., A45-FR04E flange-mounted type).
------
VI. Maintenance & Troubleshooting
1. Routine Maintenance:
• Regularly check oil level, oil quality, and oil temperature to ensure hydraulic oil cleanliness meets requirements.
• Replace hydraulic oil and filters periodically to prevent contaminants from entering the pump.
• Inspect seals and fasteners for integrity to prevent leaks and loosening.
2. Common Faults & Solutions:
• Insufficient Output Flow: Check suction line resistance and filter blockage, or adjust the variable piston to increase swashplate inclination.
• Non-Zero Oil Discharge at Neutral Position: Verify controller alignment or adjust the variable mechanism to zero position.
• Output Flow Fluctuations: Inspect the variable mechanism control piston for sticking or replace damaged components.
• Abnormal Output Pressure: Check for excessive load or adjust the relief valve setting pressure.
