Abstract
BOMBA CENTRÍFUGA. A presente revelação refere-se a aprimoramentos em bombas centrífugas, em particular, mas não exclusivamente, em bombas centrífugas de múltiplos estágios, que compreende: um invólucro (3); uma haste giratória (9) disposta para rotação no dito invólucro (3); pelo menos um estágio de bomba que compreende um impulsor preso na dita haste giratória e disposto para a rotação em uma respectiva câmara de impulsor (17) formada no dito invólucro (3); uma pluralidade de membros de vedação, em que cada um é disposto para reduzir o vazamento entre um componente giratório e um respectivo componente estacionário na dita bomba centrífuga (1); em que pelo menos um dentre os ditos membros de vedação compreende uma disposição de membros de placa compatíveis fixados em relação face a face nas extremidades de raiz ao respectivo componente estacionário e formar um anel de vedação entre o dito componente estacionário e o respectivo componente giratório; e em que o dito pelo menos um estágio de bomba tem uma velocidade específica definida como Ns = (Ômega q1/2)/(h3/4) igual ou menor do que 25, em que Ômega é uma velocidade rotacional de eixo de bomba expressa em rpm; q é uma taxa de fluxo através do estágio, expressa em m3/s no Ponto de Melhor Eficiência (BEP); e h é uma elevação de carga através do estágio expresso em m.
