Ultimate vacuum ≤1 Pa with high pumping speed in high vacuum regions
Water-cooled cooling methods for optimal performance
Corrosion-resistant flow-through components (titanium, stainless steel, or nano-ceramics)
Automatic purging device to remove condensable gases and small amounts of dust
Premium components: German seals, SKF/NSK bearings, 5-stage gear teeth
Low noise, low vibration, smooth operation with energy-efficient performance
Full certification: CE, ISO, IAF, CNAS
Product Overview
The LGV Series Dry Oil-Free Screw Vacuum Pump utilizes precision-machined parallel screws that rotate synchronously in reverse, creating sealed chambers for continuous gas conveyance. This advanced design eliminates lubrication requirements in the working chamber, ensuring clean, oil-free vacuum performance that protects both process media and the environment.
Featuring a specialized screw structure for high pumping efficiency and strong liquid discharge capacity, the pump offers a short, unobstructed pump cavity for smooth exhaust. Dynamic balance correction of the rotor and high-quality bearings ensure stable, low-vibration operation with minimal noise. Corrosion-resistant flow passage parts and an automatic purging system make it ideal for handling condensable gases, water vapor, and mildly corrosive media.
