Abstract

Centrifugal pump of the sectional-casing design, in which the casing sections (8, 9) each have a cylindrical casing shell and inner-wall parts (12-15) connected thereto in one piece. The casing shell of at least one casing section (8, 9) is composed of an outer, continuous shell part (24, 25) and of at least two separate inner shell parts (19-22) with respective associated inner-wall parts (12-15). The outer and the inner shell parts are expediently connected firmly to one another, especially by shrink bonding.
