Abstract:
1. A submersible pump, for removing liquids comprising: an enclosure having at least one outlet for discharging liquid from the enclosure, an electric actuator with a rotary output shaft, a bladed wheel mounted in the enclosure and driven by the actuator and which rotates about an axis of the output shaft, wherein a wall of the enclosure is defined by a base and includes at least one inlet orifice communicating with an outside of the enclosure, and a plate mounted in a reversible manner close to the base in two distinct configurations, a first mounting configuration being designed for the passage of a liquid laden with solid particles, the other mounting configuration being designed for the passage of a clear liquid, the enclosure having a volume that is cleared of any obstacles between the inlet orifice and the outlet socket, so as to allow the liquid (L) laden with solid particles to flow away, wherein the plate has a first face defining at least one first opening for permitting a liquid to flow toward the at least one inlet orifice and an oppositely orient second face defining at least one second opening for permitting a liquid to flow toward the at least one inlet open and being of a smaller dimension than the at least one first opening, wherein in the first mounting configuration the first face of the plate is oriented toward a support surface for the pump and wherein the plate forms with the base at least one first cavity upstream of the at least one inlet opening, the dimensions (L
