Abstract

An axially split pump for conveying a fluid includes an axially split housing with a bottom part and a cover. The bottom part has a first sealing surface and the cover has a second sealing surface. The bottom part and the cover are fastened to one another so that the two sealing surfaces are in direct contact with one another. At least one first sealing groove for the reception of a first sealing element is disposed in the sealing surfaces. A second sealing groove is disposed for the reception of a second sealing element. The first sealing groove and the second sealing groove are connected to one another through a connection region and an elastic pre-loading element is disposed in the connection region, which exerts a pre-load onto one of the two sealing elements.
