Abstract RU 2707238 C1

FIELD: pumps building.

SUBSTANCE: centrifugal pump includes housing (1). In housing (1) there are impeller (2) and suction branch pipe (4) forming suction hole and made with possibility of insertion into bottom plate (3) of pump housing. Branch pipe (4) is installed with possibility of axial movement on bottom plate (3) due to the fact that both suction branch pipe (4) and bottom plate (3) have at least one surface (6) turned relative to bottom plate (3), by which they adjoin each other so that due to scrolling of suction branch pipe (4) the distance between impeller (2) and suction branch pipe (4) can vary, and / or on radial circumferential surface (12) of suction branch pipe (4) there is sealing collar (14), in inserted state, adjacent to bottom plate (3).
