Abstract

An axially split pump for a fluid includes an axially split housing with a bottom and a cover, a rotatable shaft, and a side cover. The side cover has a first surface for cooperating with a second surface. The second surface extends over the bottom and the cover. The bottom has a first sealing surface and the cover has a second sealing surface. The bottom and the cover can be fastened so that the sealing surfaces are in direct contact. One sealing groove is in one of the sealing surfaces for the reception of a string-like sealing element, the sealing groove extending up to the second surface. A recess surrounding the shaft is in the second surface and a projection surrounding the shaft is in the first surface. The recess and the projection are arranged so that they form a ring-like groove for the reception of a ring-like sealing element.
