Abstract

Una pompa centrifuga sommersa, del tipo multistadi e girante chiusa, viene utilizzata particolarmente per l'estrazione di fluidi contenenti sabbia, terra e/o piccoli detriti da pozzi sotterranei.Ciascuno stadio della pompa comprende una camera, all'interno della quale è contenuta una girante a palette, costituita da un coperchio, un distanziatore di forma cilindrica cava ed un diffusore a palette fisse.Tra girante e coperchio vengono interposti dei mezzi di tenuta disposti e conformati in modo tale da impedire l'infiltrazione tra di essi delle sospensioni solide presenti nel fluido.(Fig. 3).
