Turbo pumps work like fans operating at centrifuge speeds.

A turbo molecular pump works much the same way as an airplane turbine. A series of very fast rotating, specially designed blades cause air to be sucked out of the vacuum chamber. It is always important to back-up these sort of pumps with a more coarse pump (like a vane rotary pump) to "clear" the gas that was sucked out and make space for more gas molecules.

Existing turbo-molecular pumps work like turbines/fans...
What I don't understand is why "they" don't use Tesla's bladeless turbine concept- basically using boundary-layer molecular forces to couple energy into the driven gas.
I'd welcome any off-line feedback.
