Abstract
A suction pump for deep wells, comprising a suction pump controlled by an electric motor, having a suction tube communicating with the inlet in the impeller and a delivery tube, which communicates with the delivery chamber, characterized by that in the lower inlet of the suction tube a venturi tube is arranged, fed, in correspondence with its narrowest section, through a profiled nozzle, by the pressurized water coming from a suitable auxiliary duct, in communication with the chamber of the pump, giving rise to a depression in correspondence with the inlet mouth of the venturi tube, which causes the aspiration of water by the down tube, submerged in the water of the well.
