BT-PNT
Features
- Rubber bellows mechanical seal
- Unbalanced
- Single spring
- Independent of direction of rotation
Advantages
The main design features of the BT-PNT are the metal joint torque transmission together with the rubber bellows. This prevents torsional effects on the bellows. The shaft is protected across the entire seal length. Easy to assemble, the BT-PNT guarantees a long service life due to good product turbulence.
