PTFE Shaft seals

Standard rubber shaft seals have only a limited range of applications. Precisely for applications where shaft rotation is required during
high pressure, temperature and chemical resistance, shaft PTFE shaft seals with fillers have been developed. This seal is further applicable in poorly lubricated or oil-free applications.
A distinctive feature of PTFE sealing blades is the reduction of frictional losses and the avoidance of "stick-slip" effect during slow movements.
Dimensionally, the seals are based on standard shaft seals for mortise DIN 3760 or ISO 6194/1.
Thanks to their compact dimensions, they can be successfully used in applications with pressure gradient at the expense of mechanical seals.
PTFE shaft seals are characterized by a high degree of individualization and customization specific conditions to the customer's requirements.

Typ T

PTFE sealing lip with fillers. Thanks to the elasticity of the PTFE material, the necessary clamping force is achieved even without the use of a tension spring.
Typ T-W

Sealing lip tensioned by tension spring. O ring made of FKM on the outer surface prevents rotation in the groove and ensures static tightness.
Type TS

Single-edged design with dust cover to prevent the penetration of dirt from the outside environment.
Type T-D

Double-walled design for separating two sealed media from each other.
Type T-T

Tandem arrangement of a pair of sealing blades for increased sealing capability.
