Abstract

patente de invenção: impulsor de bomba. a presente invenção refere-se a um impulsor de bomba que tem características antientupimento melhoradas, em particular através do usode uma palheta de impulsor que tem uma borda especialmente perfilada que, durante a operação do impulsor, força trapos ou algo semelhante para baixo ao longo da borda frontal, que aumenta em espessura ao longo do comprimento da mesma, até que os trapos reentrem no fluído e deste modo saiam do impulsor impedindo o entupimento do mesmo.
