Abstract
"BOMBA CENTRìFUGA". A presente invenção se refere a uma bomba centrífuga para bombear líquidos que contêm poluições, principalmente na forma de partículas sólidas, cuja bomba compreende uma unidade de acionamento, uma unidade hidráulica, sendo que a unidade hidráulica compreende um alojamento de bomba (20) e um impulsor de bomba (12) disposto rotativamente dentro do alojamento, o impulsor de bomba compreendendo um disco de cobertura superior (14) e um inferior (16), e diversas palhetas intermediárias (18). A invenção se caracteriza pelo fato de que uma parede de fundo (22) do alojamento de bomba, que possui uma abertura central de entrada (24), está disposta com pelo menos um dispositivo que afeta o contrafluxo que se estende em espiral (32, 34) no lado voltado para o disco de cobertura inferior, estendendo-se em espiras completas ou parciais em torno da abertura de entrada.
