• the sealing extension 90 is compressed, for example, by in particular more than 10%, preferably by more than 15%, preferably by more than 20% and very particularly preferably by more than 22% of a maximum thickness 68 of the sealing extension 90.
• the sealing extension 90 is compressed, for example, by in particular more than 5%, preferably by more than 10%, preferably by more than 15% and very particularly preferably by more than 19% of the maximum thickness 68 of the sealing extension 90.
• the sealing extension 90 is compressed, for example, by in particular more than 4%, preferably by more than 8%, preferably by more than 14% and very particularly preferably by more than 16% of the maximum thickness 68 of the sealing extension 90.
• the pressing unit 96 has at least the pressing element 98, in particular at least the clamping ring, and at least one further pressing element 100, in particular at least one further clamping ring, wherein the conveying element 22 is annular and by means of the pressing element 98 and the further pressing element 100 on an inner circumference of the annular conveying chamber element 20 is pressed, the pressing element 98 and the further pressing element 100 being arranged on opposite sides of the conveying element 22 on the conveying element 22.
• the pressing element 98 and the further pressing element 100 of the pressing unit 96 preferably have an at least substantially analogous design.
• the pressing element 98 and the further pressing element 100 are arranged mirror-symmetrically on the delivery space element 20, in particular in order to press the delivery element 22 against the delivery space element 20 and to press the sealing extension 90 into the sealing groove 88.
• the conveying chamber element 20 has at least the groove, preferably the sealing groove 88, running in particular along an inner circumference of the annular conveying chamber element 20, into which at least the sealing extension 90 of the, in particular annular, conveying element 22 is inserted by means of the pressing element 98, in particular the clamping ring, and / or of the further pressing element 100 of Pressing unit 96 is pressed in, wherein a compression of the sealing extension 90 along a, in particular running along a circumferential direction of the conveying element 22, maximum longitudinal extension of the sealing extension 90 is inhomogeneous.
