FIELD: engines and pumps.SUBSTANCE: invention relates to centrifugal pump (1) with at least one stage (2) of the pump, with a housing consisting of several parts. The first part (3) of the housing includes suction connection (5), the second part (6) of the housing includes delivery connection (7). At least one intermediate part (10) of the housing, at least in individual sections, restricts channel (11) leading to the delivery side of at least one stage of pump (2). There is also the third part (20) of the housing. The second part (6) of the housing and at least one intermediate part (10) of the housing are installed between the first and the third parts (3, 20) of the housing. At least one intermediate part (10) of the housing and the second part (6) of the housing are intended to be located at least in two different positions relative to the first and the third parts (3, 20) of the housing.EFFECT: invention is aimed at creation of a centrifugal pump, namely a multistage centrifugal pump so that different versions of connection can be created with a possibly large number of similar parts.10 cl, 5 dwg |
