Abstract

La presente invención se presenta en la modalidad de una bomba centrífuga de paso múltiple que cuenta con un ensamble sellado sustentador del empuje axial desarrollado por los impulsores de la bomba. La bomba evita la necesidad de un buje diruptivo que permite diferenciarles de alta presión. Por ello la bomba tiene particulares ventajas al utilizarse en el bombeo de líquidos que son altamente abrasivos.
