Abstract

La etapa de bombeo para una bomba centrífuga comprende una unidad impulsora (10) que tiene un cubo axial y una unidad difusora (20) extendida en una primera superficie de dicha unidad impulsora (10). La unidad impulsora (10) se soporta flotante dentro de la unidad difusora (20). Un anillo de compensación (40) se asocia con la unidad impulsora (10) y se sostiene en soporte deslizante sobre la arandela (27) alojada en una posición fija en un alojamiento (26) correspondiente de la unidad difusora (20) de una etapa de bombeo adyacente.
