Mechanical Face Seals are a special form of mechanical seals. They are also known under other designations, such as lifetime seals, floating seals, duo cone seals, toric seals and heavy duty seals.
Types:
There are two different types of Mechanical Face Seals: the most common form is Type DO, which is characterized by the use of an ORing as the secondary sealing element.
Type DF, on the other hand, has an elastomer with a diamond-shaped cross section as a secondary sealing element instead of the ORing.
Both types consist of two identical metal seal rings which seal against each other on a lapped seal face.
Technical data for metal seal rings :
Material: High-alloy, Corrosion-Resistant Cast Iron
Process: Cast
Hardness: HRC 65 To 72
Life time: More than 4000 hours
Peripheral speed: <= 3m/s
Corrosion Resistance: High
Scoring Resistance: High
Technical Data for O-Ring:
Material: NBR
Hardness: 60-65 Shore A
Temperature range: -20 °C to +100 °C
Advantages:
- Simple, reliable design
- High sealing effect against dirt, dust, water and abrasive media from the outside and against oil and grease from the inside
- Cost-effective
- Long service life
- Self-centering to compensate for shaft eccentricity or misalignment
- Maintenance-free
- Easy to assemble

Applications:
Mechanical Face Seals are predominantly used for sealing the bearings in construction machinery or production plants operating under extreme arduous conditions and subject to severe wear.
These include:
- Tracked vehicles, such as excavators and bulldozers
- Conveyor systems
- Heavy trucks
- Axles
- Tunnel boring machines
- Agriculture machines
- Mining machines
Mechanical Face Seals are proven in general machine engineering for gearboxes, mixers, stirrers, wind-driven power stations and other applications with similar conditions or where maintenance-free lifetime time sealing is expected.
