Abstract

a presente invenção se relaciona a uma montagem de impulsor para bombas centrífugas, compreendendo um primeiro elemento semelhante a disco, operativamente disposto na direção de uma entrada coaxial, voltado para um segundo elemento semelhante a disco com um diâmetro menor, operativamente disposto na direção da saída; esse segundo elemento semelhante a disco é rigidamente conectado ao primeiro elemento semelhante a disco através de um conjunto de lâminas espaçadas angularmente, e é centralmente dotado de meios de prendimento para prendimento a um eixo de acionamento. a característica distintiva da presente invenção é que as lâminas compreendem apêndices, em forma de chapa plana, adjacentes ao segundo elemento semelhante a disco, que são essencialmente localizados em correspondência com áreas sujeitas a empuxo axial menor.
