2. Turbomolecular pump - Wikipedia

   en.wikipedia.org/wiki/Turbomolecular_pump

   Interior view of a turbomolecular pump. A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. [1] [2] These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface.

3. Turbopump - Wikipedia

   en.wikipedia.org/wiki/Turbopump

   There are two common types of pumps used in turbopumps: a centrifugal pump, where the pumping is done by throwing fluid outward at high speed, or an axial-flow pump, where alternating rotating and static blades progressively raise the pressure of a fluid. Axial-flow pumps have small diameters but give relatively modest pressure increases.

   Pumps are used to move fluids around using some sort of mechanical power, from electric motors to full size diesel engines. Pumps have thousands of uses, and are the true basis to turbomachinery (Škorpík, 2017). Air compressors - Air compressors are another very popular turbomachine. They work on the principle of compression by sucking in and ...

5. Molecular drag pump - Wikipedia

   en.wikipedia.org/wiki/Molecular_drag_pump

   A molecular drag pump is a type of vacuum pump that utilizes the drag of air molecules against a rotating surface. [1] The most common sub-type is the Holweck pump, which contains a rotating cylinder with spiral grooves which direct the gas from the high vacuum side of the pump to the low vacuum side of the pump. [2]
