Design Features
- Interchangeable seal face-all combinations of materials are possible
- Integral stationary seat lock Integral stop in the rotating part prevents stationary seat from slipping axially and the mechanical seal from opening (with a carbon stationary seat there is a wearing height of up to 0.5 mm.)
- Limitation of spring movement prevents excessive face wear
- Torque transmission ensures full mobility and adaptation of the sealing surface even with small run-outs. |
