Shaft seals are essential to the reliability and environmental compliance of a vessels primary shafting.
They sit either on the forward end or both the aft and forward ends of a Stern tube on the conventional shafting of a vessel.
They can also be found on Thruster or podded type propulsion units. These seals are very similar to the aft seals found on conventional Stern tube arrangements
ATZ with our partner Aegir Marine have the parts, service and experience to overhaul most shaft seal types.
