A centrifugal pump is disclosed having a low final construction and mounting cost and in which the assembly may proceed with prefabricated machine parts of standard size. The centrifugal pump has an axial inlet pipe, an impeller, an impeller shaft connected to the impeller, a bearing block retaining the impeller shaft, and a stuffing box surrounding the shaft. A pump housing has the inlet pipe at one side, and a stuffing box housing at the other side. The pump housing is comprised of two similarly constructed spaced apart wall parts. Around a periphery of the wall parts a spiral housing is provided. The wall parts and spiral housing are positioned between two holding discs which connect the wall parts to the spiral housing. The two holding discs are held together by bolts and one of the holding discs is connected to a holding plate which in turn connects with the bearing block via a base. |
