The eccentric worm pump has a rotor (5) with rotor shaft (7) extending through a housing cover (13) and coupled to a drive outside the housing. The shaft carries a swivel bearing (22) for a guide disc (9) which is rotatably held between a plane face (10) of a housing flange (11) and the cover, and is freely movable in radial direction. The pump has its inlet chamber (6) upstream of the stator (4). These are graphite-contg. seal rings (17) in contact with the disc, one of which is contained in a contact ring (12) in the cover (13). The ring (12) is loaded by springs (15) adjustable (16) from outside. The disc (9) has a hub (21) contg. shaft seals (23, 24). |
