Mechanical seals - A2 - PNT - TSE Mechanical seals for pools

PNT graphite - Aluminium oxide

General features

Rubber bellows mechanical seal
Unbalanced
Single spring
Independent of direction of rotation
The main design features of the 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 PNT guarantees a long service life due to good product turbulence.
