摘要

The radial pump, with an impeller (2) rotatably mounted in a housing (3) and a gap sealing slide (7) axially movable between the impeller and delivery region (6), has at least one first sealing element (8) located between the gap sealing slide and the housing, and at least one second sealing element (9) located on impeller-side end face of the gap sealing slide. A threaded or ramp-like guide (10) between the gap sealing slide and housing is single-flighted or multi-flighted.
