Abstract
An automatic device for priming centrifugal pumps, characterized in that it is formed by an assembly that can be coupled to any type of pump, either horizontal axis or vertical axis, this set being formed by: an auxiliary vacuum pump connected to the pipeline of aspiration of the main centrifugal pump; a double float switch that controls the pumps, auxiliary and main, driven in turn by the level of the liquid in said suction pipe; a suction spool arranged for coupling to the suction pipe of the main pump before the suction mouth thereof; a check valve that prevents the return of air or of the gases sucked by the vacuum pump to the suction spool; and a recirculation water tank that provides the water necessary for cooling the auxiliary pump.
