ABSTRACT:
A centrifugal pump with facilitated self-priming, which comprises a casing with a suction inlet and a discharge outlet and with an internal series of diffusers and impellers, which form a cylindrical assembly that forms, together with the casing, an annular interspace which is connected to the inside of the series of diffusers and impellers on the discharge side through corresponding openings and on the inlet side through a hole arranged perimetrically in the intake region; the hole is controlled, on the side of the interspace, by a normally-open flexible metallic laminar valve. A wall of the pump struck by the fluid exiting from the interspace through the controlled hole is shaped so as to have a double symmetrical channel for imparting to the fluid a double vortex before passing through the first impeller.
