Abstract

Improvements in electric pumps equipped with tangential drive turbines, of the type consisting of a cylindrical body of vertical arrangement topped by a substantially accumulated upper portion, the assembly being arranged on a single vertical shaft driven by a single-phase electric motor with permanent running capacitor whose windings are bathed in oil, and the pump body comprising a water inlet and outlet chamber, protected by a grid, a tangentially driven vane turbine, disposed inside said inlet and outlet chamber water, a check valve of the water column of the riser pipe, and some insulation elements of the enclosure that encloses the electric motor, characterized because, above the water inlet and outlet chamber and immediately below the valve of retention, a discharge chamber is provided that is endowed with a discharge flow adapted so that, when the electromotor drive is stopped and the check valve is closed, the water contained in the discharge chamber comes out of the discharge hole and allows the electric motor to start again when the electric pump is restarted., filling first said discharge chamber and then acting the same water that fills the latter on the check valve.
