Abstract

Cette pompe (P) submersible pour évacuer des liquides, comprend une enceinte (21), une embase (3) de l'enceinte (21), comprenant au moins un orifice d'aspiration de liquide, étant adaptée pour être positionnée de manière réversible selon deux configurations distinctes de la pompe (P), une première configuration étant destinée à l'aspiration d'un liquide chargé de particules solides, l'autre configuration étant destinée à l'aspiration d'un liquide clair. L'embase (3) comprend au moins un organe (32) d'obturation d'au moins un orifice d'aspiration de liquide, adapté pour permettre la rétention étanche d'une quantité de liquide dans l'enceinte (21) en l'absence d'activation de la pompe (P).This submersible pump (P) for discharging liquids, comprises an enclosure (21), a base (3) of the enclosure (21), comprising at least one liquid suction port, being adapted to be positioned in a reversible manner. according to two distinct configurations of the pump (P), a first configuration being intended for the suction of a liquid laden with solid particles, the other configuration being intended for the suction of a clear liquid. The base (3) comprises at least one member (32) for closing off at least one liquid suction orifice, adapted to allow the tight retention of a quantity of liquid in the enclosure (21) in the 'lack of activation of the pump (P).
