Standard Seal Lip Design

The five principal lip designs, shown below identify the most common lip designs for Dichtomatik shaft seals. It is important to remember that other, more complex, designs are available for special applications. However, the lip designs shown here represent those which will fill the needs of most seal requirements.   These five principal lip designs are also supplemented by a range of more specialized designs for more specific application requirements. For additional information regarding available lip designs contact our engineering experts. 

 

S = Single Lip with A Garter Spring.

Generally used for sealing lower pressure applications. However, not recommended for use in applications where the surrounding environment contains any dirt or contaminants.

 

T = Twin Lip with A Garter Spring.

Generally used for sealing lower pressure applications. The additional dust lip provides increased protection for the primary lip. The cavity between the two lips can also be filled with grease to limit shaft corrosion and allow brief operation without media lubrication.

 

V = Single Lip

Generally used for sealing a non-pressure media, especially for sealing grease or viscous fluids. These seals are also used for dust or dirt exclusion.

 

K = Twin Lip

As type V above, but the additional dust lip provides increased protection for the primary lip. The cavity between the two lips can also be filled with grease to limit shaft corrosion and allow brief operation without media lubrication.
