The Stone Marine Seals main shaft seal EcoSeal, which was launched several years ago, is now being joined by two additional seals designed specifically for the thruster and azipod markets, the EcoSeal T and EcoSeal TS.
The EcoSeal TS is a split version of the EcoSeal T which makes for an easy retrofitting solution when replacing the more common lip type seals in use today. The T and TS can be fitted into very tight spaces and retrofitting can be carried out utilizing the old seals liners which is a significant cost saver.
Principal among the environmental advantages of fitting EcoSeals is the double barrier design of the units making it virtually impossible for any oil pollution to take place; plus the seals are fully compatible with Bio-Oils in areas of the world where these are a legal requirement, Stone Marine Seals said.
According to the manufacturer, all EcoSeals are designed to provide a long and trouble free service life with considerable attention having been paid to these requirements in both the original design and the materials used in their manufacture. Capable of operating at depths of up to 50 meters, high temperatures and at high speeds, the design compensates for any thermal expansion, hydraulic pumping or axial movement of the shaft to which they are fitted.
With a design that allows EcoSeals to be fitted to a wide diversity of ship types, from shallow draft dredgers and coastal vessels, to very deep draft heavy lift ships and semi-submersibles the EcoSeal range now provides a state of the art sealing solution to a large number of ship owners.
