Abstract

L'involucro per l'isolamento acustico è costituito da un guscio sagomato che avvolge su almeno tre fronti il gruppo motore-pompa immerso in bagno d'olio. Detto guscio è formato da una o più strutture in materiale plastico a doppia parete, a tenuta stagna nei confronti del fluido, preventivamente o periodicamente riempita/e di aria. Secondo una forma di esecuzione preferita l'involucro isolante, eventualmente supportato da idonea intelaiatura, presenta una paratia anteriore amovibile, accoppiabile al corpo principale con sistemi tradizionali. Il guscio, vincolato con fascette in materiale plastico od equivalenti alle staffe che supportano il gruppo motore-pompa, risulta parzialmente immerso nel fluido operante che circonda interamente il gruppo motore-pompa. La presenza di una o più camere di aria che in parte circondano il citato gruppo conduce ad una riduzione sostanziale della rumorosità; l'involucro isolante in materiale plastico non richiede frequenti sostituzioni, né rilascia particelle inquinanti per il fluido operante.
