Nachi UVN Series Vane Pump Unit | UVN-1A-1A2, UVN-1A-1A3 | Energy-Saving Motor Pump

UVN Series High-Efficiency Integrated Motor Vane Pump Units

Product Overview: The UVN Series is a premier energy-saving Motor Pump Unit specifically engineered for modern industrial hydraulic systems requiring low noise and high precision. By integrating a high-performance variable vane pump directly with an efficient electric motor, the UVN series eliminates alignment issues associated with traditional couplings and significantly saves installation space. This featured range highlights core models UVN-1A-1A2-1.5-4-12 and UVN-1A-1A3-2.2AE-4F-12. Its variable displacement technology ensures exceptional response and energy efficiency across varying load cycles, making it the preferred choice for CNC machine hydraulic stations.

Key Technical Advantages:

• Integrated Compact Design: Featuring a direct-connection structure between the pump and motor, removing the need for bell housings or couplings. This reduces vibration, prevents leakage, and saves critical space.

• Exceptional Energy Savings: The variable displacement vane pump automatically adjusts flow based on system pressure, drastically reducing power consumption during pressure-holding phases.

• Ultra-Quiet Operation: Optimized vane engagement and motor shielding ensure extremely low operational noise, significantly improving the workshop environment.

• High Efficiency & Longevity: Utilizing pressure-balanced vane structures, the unit maintains stable volumetric efficiency under high-pressure cycles. Built with wear-resistant materials for extended service intervals.

• Target Applications: CNC machine tools, machining centers, plastic processing machinery, automated production lines, and general industrial hydraulic power units.
