Turbomolecular Pumps: Basics And Appliions

2021-10-28 · The principle of operation of a turbomolecular pump is that gas molecules can be given a momentum in a chosen direction by repeated collisions with moving solid surfaces, therefore achieving and maintaining a high vacuum region inside the pump. A turbo pump is mainly composed of two sections: turbo and drag.

Turbomolecular pumps: what you need to know. - Leybold

2022-4-11 · If you have a high-vacuum appliion requiring a pumping speed between 50 l/s and 3000 l/s and minimum contamination from the pump, then a turbomolecular pump is an obvious choice. The lowest pumping speeds of the other key high vacuum pump types, namely diffusion and cryo pumps, are around 3000 l/s.

Turbomolecular pump operating principle - Pfeiffer Vacuum

4.9.1.1 Turbomolecular pump operating principle. The pumping effect of an arrangement consisting of rotor and stator blades is based upon the transfer of impulses from the rapidly rotating blades to the gas molecules being pumped. Molecules that collide with the blades are adsorbed there and leave the blades again after a certain period of time.
