Abstract

Le groupe motopompe est flottant et comprend un moteur électrique d'entraînement (16), une pompe centrifuge entraînée par ce moteur, et un carter (2) du groupe pour le logement du moteur d'entraînement (16) et de la pompe centrifuge. Le groupe motopompe comprend en outre au moins une ouverture d'entrée (8) disposée, à l'état d'immersion, au dessous de la surface du liquide (6) et au moins une ouverture de sortie (10, 12). L'invention est caractérisée en ce que le carter (2) du groupe motopompe est configuré et disposé de telle façon que lorsqu'il atteint une surface d'appui (44), son orientation varie par rapport à sa position d'immersion, et en ce que des moyens de commutation commandés suivant la position sont prévus à l'intérieur dudit carter (2) du groupe motopompe.
