The barrel housing of a multistage centrifugal pump has an elongated cylindrical main section and a discrete annular section which is inserted into one end portion and defines an annular shoulder facing the other end portion of the main section. The shoulder is engaged by the inner casing of the pump. The annular section can constitute a prefabricated component or is formed by cladding. The inlet opening of the housing is provided only in the one end portion of the main section, only in a portion of the annular section which extends outwardly beyond the one end portion of the main section, or is a composite opening having a first part in the one end portion of the main section and a registering second part in the annular section. The outlet opening for compressed fluid is provided in the other end portion of the main section.
