Abstract

La bomba centrífuga autocebante comprende un cuerpo de bomba (10) que tiene una cavidad interior (11) que tiene un eje longitudinal (A) dispuesto en una posición horizontal en configuración de uso que divide dicha cavidad interior (11) en una zona superior (S) y una zona inferior (I); una abertura de aspiración (12) realizada en la superficie frontal (13) de dicho cuerpo de bomba (10) en dicha zona superior (S); una cámara de bombeo (20) asociada con dicho cuerpo de bomba (10) y que tiene en su parte frontal una abertura de entrada axial (21); un grupo impulsor (22) dispuesto dentro de dicha cámara de bombeo (20); un grupo eyector (30) que se extiende dentro de dicha cavidad interna (11) del cuerpo de la bomba (10) y comprende una boquilla de expulsión (31) y un conducto de aspiración (32) que configura un perfil divergente, conectado, en la sección más ancha del mismo a la abertura de entrada (21) de la cámara de bombeo (20); un conducto de aspiración auxiliar (34) dispuesto dentro de dicha cavidad interior (11) del cuerpo de bomba (10), en dicha zona superior (S), y adaptado para poner dicha abertura de aspiración (12) en comunicación directa con dicha abertura de entrada (21) de la cámara de bombeo (20).The self-priming centrifugal pump comprises a pump body (10) having an inner cavity (11) having a longitudinal axis (A) arranged in a horizontal position in use configuration that divides said inner cavity (11) into an upper zone ( S) and a lower zone (I); a suction opening (12) made in the front surface (13) of said pump body (10) in said upper zone (S); a pumping chamber (20) associated with said pump body (10) and having in its front part an axial inlet opening (21); an impeller group (22) arranged within said pumping chamber (20); an ejector group (30) that extends inside said internal cavity (11) of the body of the pump (10) and comprises an ejection nozzle (31) and a suction conduit (32) that configures a divergent profile, connected, in the widest section thereof to the inlet opening (21) of the pumping chamber (20); an auxiliary suction conduit (34) arranged inside said internal cavity (11) of the pump body (10), in said upper zone (S), and adapted to put said suction opening (12) in direct communication with said opening inlet (21) of the pumping chamber (20).
