Design / Operating principle - pfeiffer-vacuum

4.7.1 Design / Operating principle. The principle of operation of single-stage Roots pumps corresponds to the operating principle of multi-stage pumps as described in Chapter 4.5.In the Roots vacuum pump, two synchronously counter-rotating rotors (4) rotate contactlessly in a housing (Figure 4.16).The rotors have a figure-eight configuration and are separated from one another and from the...<<more>>
