The invention concerns a device for designing the internal cooling system in a centrifugal pump. The cooling jacket (3), which surrounds the stator (2) of the electric motor, is provided with transportation pipes (7) for cooling liquid and exhaust pipes (8) for air bubbles. In order to prevent said pipes from disturbing circulating flow of cooling liquid in the slot between the stator (2) and the jacket (3), the stator is arranged eccentrically with reference to the casing (3) thus obtaining a space (10) for the pipes (7) and (8) where those do not disturb the flow. <IMAGE> |
