Abstract

um conjunto de impulsores para bombas centrífugas tem dois elementos de disco que têm diâmetros diferentes, são dispostos coaxialmente a um eixo de rotação e são voltados uns para os outros de modo a formarem um espaço intermediário; as palhetas são dispostas radialmente no espaço intermediário; os dois elementos de disco também são proporcionados centralmente com um meio de fixação para a fixação a um eixo de transmissão, o qual gira em torno do eixo de rotação. a particularidade da presente invenção reside em ter abas perfiladas que se projetam radialmente da região periférica do elemento de disco que tem o diâmetro menor e são dispostas substancialmente nas palhetas.
