PSS FLANGE & BLADDER SYSTEM
For Shaft Diameters 4” - 6” (100mm - 150mm)
Available in aluminum, mild steel and stainless steel
A large number of commercial vessels are manufactured with a multi- bolt flange in lieu of a stern tube. PYI offers fully customizable flange options to match the existing standard bolt pattern on the vessel (or blank to be drilled at installation) and facilitate the installation of the PSS Shaft Seal (or other shaft log mounted seals). These adapters can be ordered in any configuration as a “standard unit” or as an “inflatable bladder unit”. The inflatable bladder option allows the operator to seal the stern tube, while the shaft is not rotating, in order to inspect, clean, or work forward of the seal. In addition, if decoupling 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 minimal water intrusion occurring. This inflatable bladder can also be used in case of an emergency.
