Nachi UVN Series Uni-pump | UVN-1A-1A2, UVN-1A-2A, UVN-1A-1A4 | Energy-Saving Vane Pump

Nachi UVN Series Energy-Saving Variable Vane Uni-pumps

Product Overview: The Nachi UVN Series is a highly integrated power unit that directly couples a high-performance variable vane pump with an efficient electric motor. This featured selection includes key precision models: the stable UVN-1A-1A2-1.5E-4E-12, high-flow unit UVN-1A-2A-3.7A-4-20, standard configuration UVN-1A-1A4-1.5-4-12, and the customized version UVN-1A-1A3-1.5-4-Q01-6063. Thanks to the variable pump’s pressure compensation mechanism, the UVN series automatically reduces displacement upon reaching the set pressure, significantly lowering energy consumption and system heat generation. It is the premier choice for energy-saving in CNC machines, grinders, and various industrial automated hydraulic stations.

Key Technical Advantages:

• Significant Energy Savings: The variable vane structure allows displacement to adjust automatically with load pressure, reducing power consumption by over 40% during pressure-holding phases and minimizing oil temperature rise.

• Extreme Compact Integration: The Uni-pump design eliminates the need for external couplings, significantly saving installation space and simplifying maintenance routines.

• Ultra-Low Operational Noise: Optimized inlet design and precision-machined vane sets ensure silent operation across all pressure gradients, enhancing the workshop environment.

• High Responsiveness & Stability: Excellent pressure compensation characteristics ensure rapid pressure switching and minimal pulsation, improving machining precision.

• 100% OEM Compatibility: Strictly adheres to Nachi factory standards (e.g., Q01-6063 custom codes), ensuring identical mounting bases, electrical wiring, and port positions.
