Product Description
Nachi VDR-11A Series Double Variable Vane Pump
Product Overview: The Nachi VDR-11A series is a high-performance core component for industrial hydraulic systems. As a compact double variable vane pump, it integrates two independent pump cartridges on a single drive shaft, enabling independent oil supply and pressure regulation for multi-circuit systems. Featured models such as VDR-11A-1A1-1A2-13 and VDR-11A-1A3-1A3-13 are specifically engineered for machine tools, injection molding machines, and automated production lines requiring high responsiveness and low operational noise. With its precision pressure compensation mechanism, the VDR series automatically reduces displacement to a minimum once the target pressure is reached, significantly minimizing energy waste and heat generation.
Key Technical Advantages:
Independent Dual Output: Provides dual-circuit supply within a compact housing, allowing each pump stage to be set to different pressure ranges (1A1/1A2/1A3 tiers) based on load demands.
High-Precision Pressure Compensation: Features a sensitive compensator that modulates displacement once the preset pressure is achieved, delivering only the flow required to sustain pressure and maximize energy efficiency.
Industry-Leading Quiet Operation: Optimized rotor and vane geometry ensure ultra-low noise levels even under full load, enhancing the factory workspace environment.
Rapid Dynamic Response: Boasts exceptional response speeds, capable of handling instantaneous flow demands during machine reversals or press action switches to shorten cycle times.
100% OEM Standard Compatibility: Manufactured to strict Nachi factory tolerances for mounting flanges and shafts, ensuring a seamless “plug-and-play” replacement for existing hydraulic units.
