ABSTRACT:
A slide ring seal structure for sealing machine elements rotatable about an axis, especially for sealing pump shafts, with an about rotation-symmetric housing which at one end face has a bottom extending transverse to the axis of the seal structure. The slide ring seal structure also has a primary seal designed as slide ring located in the interior chamber of the housing, and further has a bellows-shaped annular secondary seal as well as a spring arranged between the slide ring and the bottom of the housing. The secondary seal has an outer cone which flares in the direction of the sliding surface of the slide ring and has associated therewith a corresponding inner cone of a clamping member coaxially surrounding the secondary seal. The axial position of the clamping member relative to the slide ring and to the secondary seal being determined solely by the axial force exerted upon the clamping member during the installation of the slide ring seal structure.
