Abstract

Spontaneous priming centrifugal pump device in which air evacuation at the periphery of the impeller takes place from inside the impeller by means of a deflection projection arranged in the casing volute in the circulation path of the entrained impulse agent through the impeller at its periphery by dragging action, a projection that again pushes into the impeller cells a partial current of the entrained liquid, is approximated at least until near the periphery of the impeller and arranged immediately before the start of the spiral of pressure, characterized in that the projection is able to yield elastically at least radially towards the axis of the impeller.
