Abstract

"DISPOSITIVO PARA O BOMBEAMENTO DE LìQUIDOS". A presente invenção refere-se a um dispositivo para o bombeamento de líquidos, principalmente de líquidos de corte contendo resíduos de processos de produção. Tal dispositivo é equipado com uma bomba vertical compreendendo um corpo da bomba (14) e um rotor de bomba (13), adicionalmente a um eixo do motor (19), um motor elétrico e uma junção de eixo entre o motor elétrico e o rotor da bomba (13). O eixo do motor (1 9) é cercado por uma carcaça (18). O corpo da bomba (14) possui uma abertura de aspiração (15) e uma abertura de descarga de líquido (16). Quando a bomba dá a partida, uma baixa pressão é gerada no corpo da bomba (18) que envolve o eixo do motor (19), essa pressão continua até dentro do corpo da bomba (14) através de uma fenda (22) entre o eixo do motor (19) e o corpo da bomba (18) garantindo assim o bombeamento do líquido mesmo quando o nível do mesmo é extremamente baixo.
