Abstract
Centrifugal pump particularly for domestic use, characterized in that in the space (14 ") formed in the pump body above the suction (15) and delivery (16) chambers, a drain pipe (42) opens out to extends inside the nozzle or the expulsion tube (28) to the end of this tube, having as function this drain tube (42) evacuating by siphoning the water that may have spilled in this chamber (14 ") and have reached the exit orifice of the tube.
