摘要

The pump, and especially a rotary or free-flowing pump, has a housing (2) of cut sheet plate sections with a cover plate (12) and a base plate (13) and a bent spiral side strap (14). The housing components are locked together by matching projections in one piece with the side straps, and recess openings. The housing plate sections are cut by a laser.
