Product Description
Nachi UVN Series Energy-Saving Combination Pumps for Machine Tool Replacement
Product Overview: The Nachi UVN Series (Unipump) is the definitive solution for energy efficiency and space optimization in machine tool hydraulic systems. This series perfectly integrates a high-performance variable vane pump with a customized high-efficiency motor, eliminating the need for traditional couplings and bell housings. This selection features three primary maintenance models: UVN-1A-1A3-1.5-4-6267B, UVN-1A-0A2-0.7-4-11, and UVN-1A-2A3-2.2-4-12U. With its superior reliability and ultra-low noise levels, the UVN series is the premier OEM-grade replacement for hydraulic power units in Okuma, Mazak, Makino, and other leading global machine tool brands.
Key Technical Advantages:
Direct OEM Replacement: Specifically designed for the machine tool industry, with interface dimensions and performance specs matching original HPUs for a “plug-and-play” installation.
Significant Energy Savings: The variable displacement mechanism automatically adjusts flow based on the machine’s duty cycle (clamping, indexing, standby), reducing power consumption by over 30% compared to fixed-pump systems.
Ultra-Compact Architecture: The motor shaft serves as the pump shaft, reducing the overall length by over 40%, significantly saving space within the machine enclosure.
Whisper-Quiet Operation: Optimized for factory environments, it maintains exceptional silence even under high-pressure loads, improving operator comfort.
High Reliability & Low Maintenance: No alignment required, eliminating coupling failure risks and drastically reducing unplanned downtime.
Target Applications: CNC lathe hydraulic chuck drives, tool turret indexing systems, machining center coolant systems, and automated hydraulic fixtures.
Detailed Models & Parameters:
Core Series: Nachi Fujikoshi UVN Series Combination Unipump.
Model Keywords: UVN-1A-1A3-1.5, UVN-1A-0A2-0.7, UVN-1A-2A3-2.2, 6267B, 12U.
