Abstract

<B><MU>PROCESSO E APARELHO PARA BOMBEAR UM MATERIAL VISCOSO E QUE CONTéM GáS E ROTOR PARA O USO EM CONEXãO COM O APARELHO<D><MV> A presente invenção refere-se a um processo e aparelho para bombear um material e um rotor usado no referido aparelho. Especialmente de preferência, o processo, aparelho e rotor de acordo com a invenção são adequados para bombearem suspensões de fibras espessas, que contêm gás, sendo o gás na maioria das vezes ar, da indústria de processamento de madeira. O processo, aparelho e rotor (552) da invenção são caracterizados pelo fato de que a polpa em questão é bombeada por meio de uma bomba centrífuga que utiliza um rotor (522), cujas lâminas (562) foram torcidas de maneira que o seu passo muda ao longo de uma parte essencial do comprimento do rotor (522).
