Abstract:
To ensure that liquid and/or vapors do not escape from a tank space during cleaning by means of cleaning equipment, a housing (2) is provided with magnetic coupling equipment according to the invention, comprising two cooperating pole elements (8,9) which extend hermetically isolated from each other with pole parts extending in the turbine housing (3) on the tank space side and the gear housing (1) itself outside the tank space, respectively. This provides a considerable degree of security against liquid and gas leakage, while making it possible to achieve a compact structure with easy access for service and maintenance.
