Abstract

1. Bomba centrífuga multietapa, en particular para impulsar líquidos en las proximidades de su punto de ebullición, que está sumergida por el lado aspirante en una cubeta para la afluencia del líquido, caracterizada porque en la carcasa de la segunda etapa de la bomba o de otra etapa de la bomba se ha dispuesto una brida anular (7) para la fijación sobre la cubeta (1). 2. Bomba centrífuga según la reivindicación 1, caracterizada porque la brida anular (7) se ha dispuesto en la última o en la penúltima parte (4, 6) de la carcasa en forma de etapas. 3. Bomba centrífuga según las reivindicaciones 1 ó 2, caracterizada porque la brida anular (7) se ha configurado en forma de tapa de la cubeta (1). 4. Bomba centrífuga según una de las reivindicaciones 1 a 3, caracterizada porque se ha dispuesto sobre la tapa (7) de la cubeta (1) la tubuladora de entrada (8). 5. Bomba centrífuga según una de las reivindicaciones 1 a 4, caracterizada porque la cubeta contiene nervaduras directrices del flujo. 6. Bomba centrífuga según una de las reivindicaciones 1 a 5, caracterizada porque la entrada (9) en la cubeta (1) se ha configurado como difusor al menos perfectamente redondeado. 7. Bomba centrífuga según una de las reivindicaciones 1 a 6, caracterizada porque entre la entrada de la bomba (3) y la pared (10) de la cubeta (1) opuesta a la entrada de la bomba, existe una distancia que corresponde al menos al diámetro de la entrada a la bomba. 8. Bomba centrífuga multietapa.
