Permanent Magnet Variable Frequency Centrifugal Vacuum Pump

The magnetic levitation centrifugal vacuum pump integrates mature technologies such as magnetic levitation, frequency conversion, high-speed permanent magnet synchronous motor and high-speed impeller. The active levitation magnetic bearing can keep the vacuum pump rotor in the best position. The frequency conversion technology realizes the low-current start-up and full-condition intelligent adjustment of the vacuum pump. The application of high-speed motor and high-speed impeller realizes high efficiency of the whole machine, small size and light weight. Compared with traditional vacuum pumps, magnetic levitation centrifugal vacuum pumps have no gear, no need for lubricating oil, low vibration, low noise, and can save energy by about 20%.
