PROBLEM TO BE SOLVED: To easily adapt a frictional vacuum pump to various kinds of applications requested by customers. SOLUTION: The friction vacuum pump (1) comprises a chassis (5), a stator (3), a rotor (4) and a housing. All functional elements of the pump are combined into one unit (27). The unit itself is inserted into housings (19, 55) adapted to a specific application. Using this procedure, any special connection housing can be eliminated and optimal conductance can be achieved.
