Profile: SAP Parts is a manufacturer and exporter of mechanical face seals. Mechanical face seals or duo cone seals are specifically engineered for rotating applications in extremely arduous environments where they withstand severe wear and prevent ingress of harsh & abrasive external media. There are two different types of mechanical face seals. Both types consist of two identical metal seal rings mounted in two separate housings face-to-face on a lapped seal face. The metal rings are centered within their housings by an elastomer element. One half of the mechanical face seal remains static in the housing, while the other half rotates with its counter face.
