Abstract

Bomba centrifuga perfeccionada con cebado automático, que comprende un cuerpo de bomba provisto de al menos tres orificios, uno para la aspiración, un segundo para la impulsión, un tercero para la carga inicial, caracterizada porque; el cuerpo de bomba es una estructura segmentada en varios pasos en el que cada paso esta constituido por una célula elemental estando ensambladas dichas células entre si por apilamiento; la célula elemental que constituye el paso inferior de dicho apilamiento comprenden en su base una cara o costado, llamado de cebado, que tiene la forma de un disco vaciado centralmente; y porque el contorno de la zona vaciada está, sobre la cara superior del costado, perfilado formando acanaladuras que sobresalen de dicha cara según una dirección que forma con dicho superficie un ángulo agudo, teniendo dicho perfil acanalado por efecto, imponer al flujo recibido por dicho costado, una dirección ascendente predeterminada hacia la cámara de difusión de la célula inferior.
