FLANGE & BLADDER SYSTEM
Depending on shaft size and coupling system
Many commercial vessels are manufactured with a multi bolt flange in lieu of a stern tube.
These flanges generally have a symmetrical standard bolt pattern. To facilitate the installation of PSS seals, PYI manufactures a wide variety of flanges that fit standard bolt symmetrical flanges and transform the flange into a ready horn for coupling the PSS mechanical seal. These couplings can be ordered as a “standard unit” or as an “inflatable chamber unit”.
- The inflatable bladder option allows the operator to seal the stern tube, while the shaft is not rotating, to inspect or clean the seal. In addition, if the uncoupling of the shaft is needed, this operation can be done in the water as the shaft can be moved aft with the bladder inflated with no water intrusion occurring. This inflatable bladder can also be used in case of an emergency.
