On exceptionally large pumps, agitators, mixers, autoclaves, filters, calenders, fermenters and similar units with large shafts there is often a tendency for the shafts to wander well off center.
This is evident not only in axial and radial movements but also in pendulating movements.
Conventional mechanical seals cannot cope with these extreme conditions. For these applications DEPAC can offer seal type 365 with “floating” seal faces which absorb these extreme movements in the seal itself and still hold the faces together with the same pressure conditions.
These mechanical seals work reliably and completely independently of any shaft movements.
Maximum temperature / pressure / speed indicates operating extremes independently and does not imply the seal will function at these extremes at the same time. Contact Pactor if in doubt.
