Abstract: A shaft sealing arrangement for a pump for delivering hot fluids includes a dynamic shaft seal (4), in particular a slide ring seal, in order to seal a rotatable shaft (2) relative to a housing (1), and a cooling ring (5) which is mounted in front of the dynamic shaft seal (4) in the direction of the pump interior and which surrounds the shaft (2) at a small spacing. The shaft sealing arrangement further includes an additional seal (8) which seals the shaft (2) in the region of the cooling ring (5) in order to reduce the feed of hot fluid into the gap between the shaft (2) and the cooling ring (5), with the additional seal (8) being formed as a brush seal.

Abstract: A pump for the transporting of fluids and/or of mixtures of fluids includes a housing (1) and at least one restrictor gap seal which is provided in the housing (1) to reduce the pressure in a restrictor gap along a rotatable part (2) of the pump, wherein the restrictor gap seal is formed as a brush seal arrangement (8). The brush seal arrangement (8) contains one or more individual brush seals (8?) which include as sealing members a plurality of sealingly arranged fibers, bristles and/or wires (8a) which are distributed and fastened in ring form and whose free ends extend towards the surface to be sealed.

Abstract: A flow machine for a fluid is presented with a radial sealing gap (9) between stator parts (4) and a rotor (3), wherein at least one wear ring (5) is provided at the sealing gap and is fastened to a stator part (4) via an elastically deformable fastening part. The fastening part (6) is connected on the one side to the stator part (4). On this side a radial gap (8) is formed between an outer jacket surface of the wear ring and the fastening part and, on the other side, with the wear ring. On this side a radial gap (7) is formed between an outer jacket surface of the fastening part and the stator part.

Abstract: The high pressure rotary pump in a pot housing includes a pressure cap (3). The latter has a flange part with a flange (4) with which the pressure cap is fastened to an end face and annular sealing surface (20) of a housing (2) by being screwed into place. The flange is elastically deformed by being screwed into place. The sealing surface of the housing in the region of a base zone of the flange stands in contact on this with a second sealing surface (40). The two sealing surfaces (20, 40) lie on two at least approximately radially extending conical or annular surfaces prior to the being screwed up. These two surfaces enclose an angle ? which opens outwardly with respect to a central axis (101). After the screwing into place of the flange, the two sealing surfaces are pressed onto one another due to its elastic deformations and thus the angle between the sealing surfaces is equal to zero.
