Abstract (en)
[origin: EP2535591A1] The pump has a fixed seal ring (16) sealingly connected with an impeller (12), and resting against a wall (18) of a housing that surrounds the impeller. The sealing ring surrounds an inlet opening (20) in the wall and is fixed in a radial direction by two projections formed on the wall. The projections are engaged with recesses (26) that are formed at an outer peripheral part of the seal ring. The projections are designed as threaded pins or threaded sleeves (22), and the recesses are formed parallel to a central axis (X) of the seal ring.
