Technology

A turbopump is a gas turbine that is made up of two independent components ; a rotodynamic pump and a driving turbine. They can be mounted on the same shaft or customarily geared together. The design of a turbopump is to produce a high pressure fluid for feeding a combustion chamber or other use. Visit the turbo pump wiki page for more information.

A turbomolecular pump is a form of vacuum pump similar to a turbopump which is used to obtain and hold a high vacuum. These pumps work on the principle that gas particles can be given momentum in a wanted direction by reiterated collision with a traveling solid surface. In a turbomolecular pump, a quickly spinning turbine rotor 'strikes' gas particles from the intake of the pump towards the exhaust in order to make or hold a vacuum.
