Mechanical Face Seals or are specifically engineered for rotating applications in extremely arduous environments where they withstand severe wear and prevent ingress of harsh and abrasive external media. A Mechanical Face Seal is also known as Heavy Duty Seal, Face Seal, Lifetime Seal, Floating Seal, Duo Cone Seal, Toric Seal , Mechanische Laufwerkdichtungen (German), Механични Челни Уплътнения (Bulgarian), Mekaniske aksialtætninger(Danish), Mekaaninen otsatiiviste (Finnish), Joints d'Etanchéité Axiaux (French),Mechaniczne Uszczelnienie Czołowe (Polish), Juntas espejo (Spanish), Mekaniska Glidringstätningar (Swedish).
There are two different types of Mechanical Face Seals / Heavy Duty 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.
