These are positioned opposite to each other, and are separated by the housing base (9) of the main chamber (1), which consists of a non-magnetisable material. Fore chamber (2) and main chamber (1) are connected by a rising pipe (17). The opening (18) of the pipe is at a distance to the main chamber housing base. The fore pump has a pump rotor (13) with magnets.
