Recirculation pump for pipeline section has inflatable sealing hose for sealing axial annular gap between entry opening of pump housing mantle and pump intake pipeline section

摘要

The recirculation pump (16) has a housing mantle (18) with entry and exit openings (26,28), perpendicular to the pump longitudinal axis (30), which are connected to the pipeline (14). The housing mantle has an attached vertical guide (34) for a vertical guide rod (36), for adjustment of the pump and a sealing hose (60) can be inflated for sealing the axial annular gap (57) between the pipeline opening (40) and the pump housing mantle entry opening.
