Abstract
Improvements in the internal self-priming system of centrifugal pumps, characterized by the adequate disposition inside the pump body, of a perfectly dimensioned conduit of direct communication from the widening of the impulse wedding to the spiral box near the initiation tongue of the spiral of the volute and the incorporation of a impeller impeller whose particular characteristic is the one of having one, two or three channels at most, open or closed, of decreasing section from its axial entrance until its exit to the periphery, constituting the set a self-priming centrifugal pump.
