Enerseal® Spring Energized Seals
Energized Rotary Seals U
OVERVIEW
Le guarnizioni per alberi rotanti RotoEnerseal®
sono costituite da un jaket in ptfe o UHMWPE, espanso da molla in acciaio inox. Queste tenute sono caratterizzate da un basso coefficiente d'attrito e dal mantenimento del precarico nel tempo. Le tenute rotanti energizzate RotoEnerseal® sono sicure e versatili, suscettibili di impiego nei settori più svariati, dall'Oil & Gas all'industria chimica ed al trattamento dei prodotti alimentari e farmaceutici. Per questi ultimi impieghi le versioni con molla ad U sono fornite con riempimento in silicone alimentare a norma FDA ed EU e, a richiesta, sono certificate secondo le norme MOCA
