Product Description
Nachi Type PVS Series High-Efficiency Variable Displacement Vane Pumps
Product Overview: The PVS Series variable displacement vane pump represents the cutting edge of hydraulic energy-saving technology. Featuring a unique semi-cylindrical swash plate structure, it automatically adjusts displacement in real-time according to system pressure demands, delivering precise “oil on demand.” This range includes the premium models PVS12EH140C2, PVS12AZ140C2, PVS20EH140C2, PVS25EH140C2, and PVS25EH140C2Z. With its compact design and optimized pressure-balance mechanism, the PVS series maintains minimal heat generation and ultra-low noise levels even at 14.0 MPa (140 Bar), making it the industry-recognized power source for precision machining.
Key Technical Advantages:
Significant Energy Savings: The automatic variable mechanism drastically reduces throttling and overflow losses. Minimal system temperature rise leads to 30% – 50% power savings.
Ultra-Quiet Performance: Utilizing patented swash plate and vane geometry to eliminate fluid pulsation, ensuring a whisper-quiet workshop environment.
Rapid Dynamic Response: Features highly sensitive pressure-compensated switching, ensuring actuators move precisely and without lag during frequent start-stop or pressure-holding cycles.
High-Pressure Durability: Rated for continuous operation at 14.0 MPa. Specialized wear-resistant treatments and robust swash plate supports ensure a maintenance-free service life of tens of thousands of hours.
Target Applications: CNC lathes, machining centers, hydraulic grinders, light-duty injection molding machines, automated lines, and high-performance HPU systems.
