Abstract

En las bombas centrífugas y, en particular, en las bombas para transferir fluidos, que contienen partículas abrasivas como las bombas de lodo, el desgaste de las áreas húmedas es un problema importante de mantenimiento. La invención provee la protección de superficies internas vulnerables al desgaste por tales partículas, al proveer medios para ajustar y controlar la distribución del fluido de sello para descargar áreas vulnerables. La invención se extiende a un método y un kit de retro-adaptación, pero proporciona principalmente un conjunto de bomba centrífuga, que comprende un impulsor montado de manera giratoria en él y medios de soporte dispuestos de manera operativa para soportar el impulsor desde su lado de succión, en relación de estanqueidad con la carcasa. Los medios de sellado se pueden ajustar de manera mecánica, para una distribución sustancialmente uniforme del fluido de sello, a ambos lados axiales del impulsor en la carcasa de la bomba.
