Nachi UVN Series Vane Pump Unit | UVN-1A-1A3, UVN-1A-1A4 | 1.5kW & 2.2kW 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 ultra-low noise and superior precision. By integrating a high-performance variable vane pump directly with a high-efficiency electric motor, the UVN series eliminates alignment issues and vibration associated with traditional couplings. This featured range includes the specialized model UVN-1A-1A3-15-4-Q01-6063C, alongside standard configurations UVN-1A-1A4-1.5-4-11, UVN-1A-1A4-2.2-4-11, and UVN-1A-1A3-2.2-4-1. Its advanced pressure-compensation technology significantly reduces power consumption during pressure-holding phases, making it the definitive power source for CNC machine hydraulic stations.

Key Technical Advantages:

• Energy Savings & Low Heat: Utilizing variable displacement logic, the pump automatically adjusts flow based on load pressure. During pressure-holding, flow drops to a minimum, drastically cutting power loss and preventing oil overheating.

• Integrated Compact Structure: Featuring a direct-connection design that removes the need for bell housings or couplings. This structure saves over 30% of installation space while enhancing overall operational stability.

• Ultra-Quiet Performance: Optimized vane inlet and outlet designs, combined with motor shielding, keep operational noise at an absolute minimum, significantly improving the workplace environment.

• Fast Response & Reliability: Exceptional pressure compensation response times ensure that hydraulic power is delivered without delay during high-speed CNC cutting or tool changes.

• Target Applications: CNC machine tools, grinding machines, precision forming equipment, robotic hydraulic stations, and various compact power units.
