<p>A closure bottom plate 1 for electric pump 100, in particular for a boiler circulation centrifugal pump, having an integrated system for removing the internal condensate, such plate being extremely easy to manufacture and assemble, comprises: a motor cover 2 cup-shaped and provided with coupling opening 21, arranged to be associated, closing it, to the end of a box-shaped containment body 102 of the electric pump; and a connector-holder cover 3, associable in a mounted configuration to the coupling opening 21, in turn comprising fixing means 30 arranged to hold at least one electrical connector 300 in a preset position of connection to the electric pump 100. The bottom plate 1 has an internal aeration path 4, intended to allow the circulation - by natural convection - of the air which is heated during the operation of the electric pump 100 preventing the formation of condensate inside the bottom plate 1. Such internal aeration path 4 is extended between at least one inlet opening 22 arranged on the motor cover 2 and an outlet opening 36, successively crossing the internal volume of the motor cover 2, the coupling opening 21, and a labyrinth 32 defined by the connector-holder cover 3.</p> |
