4 month ago
Product details
I. Product Overview
TheA145-FR01BS-60is a high-end variable hydraulic piston pump fromYUKEN, a leading brand in Japan's hydraulic component industry. Belonging to theA-serieswith large displacement, this pump features aswashplate variable mechanismthat enables stepless displacement adjustment by modulating the swashplate angle, meeting dynamic pressure and flow demands in hydraulic systems. With a rated pressure of35 MPa, it is suitable for high-pressure, high-flow industrial applications.

II. Key Design Features
1. Swashplate Variable Mechanism
• Adjusts displacement continuously via mechanical or hydraulic regulation of the swashplate angle, offering fast response and high precision.
• Flexible variable control supports modes such asPressure Compensation (PC)andLoad Sensing (LS)to adapt to diverse operating conditions.
2. High-Pressure Design
• Rated pressure:35 MPa(with higher transient peak pressure capability) for heavy-duty and shock-load applications.
• Critical components (e.g., pistons, cylinder blocks, valve plates) are made of high-strength alloy steel with quenched and precision-ground surfaces, ensuring wear resistance and fatigue endurance for tens of thousands of operating hours.
3. High Efficiency & Low Noise
• Volumetric efficiency up to98%(at 16 MPa pressure and 1,800 rpm), with total efficiency exceeding90%, minimizing energy loss and fuel consumption.
• Optimized flow path design reduces hydraulic shock and turbulence, operating at noise levels below60 dB, outperforming average同类 products (similar products).
4. Modular Structure
• Integrates functional modules such as charge pumps, control valves, and filters, simplifying piping connections and reducing leakage risks.
• Supports multiple mounting options (e.g., flange or base mounting) for direct coupling with motors or engines, lowering system complexity.
5. Energy-Saving & Environmentally Friendly
• Load-sensing control automatically adjusts displacement based on system demand, preventing over-supply and saving energy.
• Low heat generation reduces oil temperature rise, allowing smaller tank sizes and compact equipment footprints.
