Dry Scroll Vacuum Pump – NST Series

NST series dry scroll vacuum pump is constructed with fixed scrolls, orbiting scroll, main shaft, cooling fans, crank shaft kits, and bracket.

Its’ operating principle is based on two spiral cylinders, one offset and orbiting against the other with an offset of 180°. Thus several crescent-shaped pockets of differing sizes are created. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gases from the outside towards the inside thereby pumping the gases from vacuum chamber.




Wide range of pumping speed, from 1L/S to 16L/S
Ultimate pressure upto 1Pa
Suitable for any type of power supply around the world,110/220/380/460, 50/60HZ
No oil back-diffusion or exhaust
Can be repeatedly continuous operated between atmospheric and vacuum.
Low vibration, low noise and high efficiency
Ease of maintenance, small volume, light weight
