GMB-300CM
Feature：
1.Light-weighted, small size, large pumping volume; special coating treatment for anti-erosion.
2.Special shaft seal design prevented the entry of particulates to damage the pump.
3.High vacuum, low noise and low vibration
4.Optional magnetic coupling, start up by atmosphere and shorten pumping time
5.Magnetic coupling with air cooling design protected magnetic coupling against high temperature which occurred due to magnetic field cutting, affected the performance of magnetic coupling.
