Abstract
Automatic priming centrifugal pump, which is characterized by being equipped with a lower chamber in communication in the liquid circuit driven by centrifugal force of the vane wheel, and separated from the entrance duct by a partition in which a hole is made oriented towards said wheel, provided at the bottom with a tilting blade capable, in its two extreme positions, of sealing respectively said orifice and to which said chamber communicates with the pump circuit in the outlet direction, provided in the orifice of the pump. Liquid inlet to the pump a unidirectional valve and the automatic priming of the same occurs by initial recirculation of the liquid retained in its lower chamber.
