Abstract

La divulgación se relaciona con una camisa de succión (8) para una bomba centrífuga (1) para el procesamiento de pulpas, la bomba centrífuga comprende un impulsor (3) alojado en una carcasa (2), la camisa de succión (8) comprende una porción cilíndrica (10) que se puede disponer en la carcasa (2) de la bomba centrífuga (1), y una porción de brida (11) que se proyecta hacia afuera en una dirección radial desde la porción cilíndrica (10); la porción de brida (11) se puede disponer de manera tal que cuando se encuentra montada en una bomba centrífuga (1), al menos una porción de una superficie de extremo frontal (12) de la porción de brida (11) de la camisa de succión (8) está en contacto con al menos una porción de un extremo frontal (14) del impulsor (3), de manera de sellar una separación axial entre la camisa de succión (8) y el impulsor (3), y donde al menos la superficie de extremo frontal (12) de la porción de brida (11) está fabricada de un polímero de baja fricción; la divulgación además se relaciona con una bomba centrífuga (1) para el procesamiento de pulpas, la bomba centrífuga comprende una camisa de succión (8); la camisa de succión (8) y la bomba centrífuga (1) pueden prevenir la recirculación del fluido bombeado en una bomba centrífuga, con lo que se reduce el desgaste.
