The pump consists of a centrifugal pump and a drive motor, forming an immersion pump unit enclosed in a casing (1) with a selectively applicable cooling jacket (6). The jacket has an outlet (10) that can be connected to a supply line. The casing has outer surfaces against which the inner surfaces of the cooling jacket can be brought and seals (8,9) closing the gaps between the casing and the cooling jacket. |
