Abstract

Patente de Invenção: <B>"APERFEIçOAMENTOS EM BOMBAS"<D>. Bomba de fluido (10), compreendendo um corpo (14) alojando uma câmara de bombeamento de fluido, possuindo um membro rotativo de bombeamento (16), um eixo de acionamento (12), o qual passa através de uma abertura no corpo, para o interior da câmara de bombeamento, a fim de afetar a rotação do membro de bombeamento em uso, e uma vedação (18) entre o corpo de bomba e o eixo rotativo, para inibir um movimento de fluido ao longo do eixo, para o exterior da câmara de bombeamento, caracterizada por um selamento divisório (32), operacionalmente localizado entre a vedação e o membro de bombeamento rotativo, para dividir a câmara de vedação (30) entre a vedação e o membro de bombeamento rotativo.
