Abstract

La invención se refiere a una bomba multietapa sumergible (1) que comprende una unidad de accionamiento (2) con un motor eléctrico (10) y un eje de accionamiento (12), donde el eje de accionamiento (12) se extiende en dirección axial, y una unidad hidráulica (3) conectada a la unidad de accionamiento (2) y que comprende una etapa de presión de entrada, una etapa de presión de salida y un elemento superior (19) conectados en serie, en donde el elemento superior (19) comprende una salida (5) de la bomba multietapa (1). La etapa de presión de entrada de la unidad hidráulica (3) comprende una entrada axial (29) y una salida axial (30), una carcasa circunferencial (21), un difusor interno circunferencial (22) y un impulsor (20) conectado al eje de accionamiento (12) de la unidad de accionamiento (2), en donde la carcasa (21), el difusor (22) y el impulsor (20) de la etapa de presión de entrada definen una trayectoria de flujo desde la entrada axial (29) hasta la salida axial (30), y en donde el difusor (22) está conectado a la carcasa (21). La bomba se caracteriza porque la etapa de presión de entrada presenta holgura radial entre la carcasa (21) y el difusor (22) en dirección radial, y apoyo entre la carcasa (21) y el difusor (22) en la dirección axial.
