Product Description
Nachi UVN & UPV Series Energy-Saving Motor Combination Pumps
**Product Overview: ** The Nachi UVN and UPV Series represent cutting-edge solutions for energy efficiency and compactness in modern hydraulic systems. As pioneers of the Unipump concept, these units directly couple high-performance variable pumps (UVN Vane / UPV Piston) with high-efficiency motors. This featured selection includes: UPV-2A-35N1-37A-4-4211A, UVN-1A-0A3-0.7-4-11, and UVN-1A-1A3-1.5-4-12. Eliminating the need for couplings, these compact units are the premier choice for CNC machine tools, hydraulic clamping systems, automated production lines, and compact Hydraulic Power Units (HPU).
Key Technical Advantages:
Exceptional Energy Savings: The variable displacement mechanism automatically adjusts flow based on demand, drastically reducing power consumption during high-pressure holding phases by up to 30%-40%.
Integrated Compact Architecture: The pump and motor share a single shaft, removing traditional bell housings and couplings. This eliminates alignment errors and significantly minimizes the installation footprint.
Low Noise & Vibration: Precision matching between the pump body and motor frame ensures ultra-quiet operation, fostering a better working environment.
Excellent Self-Priming & Response: Both UPV (Piston) and UVN (Vane) units offer agile pressure-compensation response, ensuring smooth system operation.
Simplified Maintenance: The modular design streamlines installation and minimizes downtime caused by coupling-related failures.
Target Applications: CNC lathe spindle drives, hydraulic chuck control, industrial robotic power stations, and precision grinders.
Detailed Models & Parameters:
Core Series: Nachi Fujikoshi Unipump Series.
Model Keywords: UPV-2A-35, UVN-1A-0A3, UVN-1A-1A3, 37A-4, 0.7-4, 1.5-4.
