Leakage from seal faces is directed to a liquid collection system. A vessel with a high level alarm is provided for detection of excess leakage.
Questo rivoluzionario design è il risultato della più intensa ricerca Sealtek sui sistemi di tenuta, e costituisce la prima vera innovazione nel mercato delle tenute da molti anni. Fino ad ora, tutte le tenute meccaniche a cartuccia sono state disegnate con una bussola integrata.
Il design rivoluzionario della Style 600SL permette l’installazione su pompe dove era prima considerato impossibile montare una tenuta meccanica. Il design senza bussola permette inoltre una maggior tolleranza al disallineamento dell’albero.
La 600SL è la prima tenuta a cartuccia ad incorporare un’estensione conica della cassa stoppa, permettendole di migliorare sensibilmente la vita operativa della tenuta in applicazioni di slurry e fluidi carichi. Senza alcuna parte dentro la cassa stoppa, le particelle solide dei fluidi hanno spazio per circolare e non si depositano sulle facce di tenuta.
Questa tenuta è dotata di flangia con connessione per flussaggio e massicce facce di tenuta realizzate in materiali sinterizzati montati su elastomeri flessibili, che agiscono anche da assorbitori di shock, e offre la più grande affidabilità alle condizioni operative più severe.
La Style 600SL offre all’utilizzatore concreti benefici in termini di risparmio sull’acquisto della tenuta, dei pezzi di ricambio e sul fermo macchine.
