A turbomolecular pump is a type of high vacuum pump. These pumps create a vacuum by giving gas molecules momentum by repeated collision with a rapidly spinning turbine rotor. The rotor blades collide with gas molecules from the inlet of the pump which propels them towards the exhaust in order to create or maintain a state of low pressure (a vacuum).
Turbopumps are ideal for scientific and R&D applications including mass spectrometry, solar research, thin film coating and more. Industrial applications include the manufacture of micro-electronics (semiconducting) and renewable energy applications.
