Abstract

Perfeccionamientos en bombas, especialmente en bombas de barril, con un rotor de bomba, propulsado a través de un árbol de rotor por un motor, por ejemplo por un motor eléctrico o un motor de aire comprimido, con el líquido es elevado por bombeo en un canal anular situado entre un tubo de soporte para el árbol de rotor y una envolvente de alojamiento con forma tubular hacia una salida unida con este canal anular, y con al menos un canal de derrame, que sirve para la evacuación del líquido de derrame que procede del tubo de soporte, caracterizados porque el canal de derrame está conducido de modo estanco a través del canal anular, partiendo del tubo de soporte y desemboca en un lugar situado por debajo de la salida por fuera de la envolvente de alojamiento.
