Abstract

Electric pump for the impulsion of liquids comprises a suction chamber (5), a diffusion chamber and a pressure chamber (6) through which the impelled liquid exits. The portion of the pump body (2) that delimits said pressure chamber (6) is provided with at least two external suction inlets (9;9'), adapted for receiving the liquid to be impelled, and a selection device (10) which, acting as if it were a valve, selectively permits the inflow of the liquid by one of the inlet channels, by several channels at the same time, or by none, adapting itself to the different needs of the installation.
