2. Fluid-powered kinetic pumps

This group includes several pump types based on the same physical principle.

We distinguish between two subgroups:

the first, essentially intended for industrial vacuum (or rough vacuum), covering the pressure range from one atmosphere down to a few pascals;
the latter ranging from a few pascals to high vacuum and ultra-high vacuum.

2.1 Ejector vacuum pump

Normative definition: "A kinetic pump that uses the negative pressure created by a Venturi effect and in which the gas is carried in a high-velocity jet towards the discharge. An ejector operates correctly under viscous or intermediate regime conditions."...
