Type 4600 with Shut Down Seal


The water-lubricated stern tube seals type 4600 from EagleBurgmann are not alone an environment-friendly solution. They meet all technical requirements of modern sealing technology: modular design, convenient installation, little maintenance, no adjustments. Applying a shut down seal eliminates costly and time-consuming dry-docking. Maintenance and repairs can be performed with vessel afloat.
Type 4600 water-lubricated stern tube seals are virtually leak-free and are leaving no oil or grease residues in the waterway. And because they prevent getting water into the bilge, no elaborate actions are required for its disposal.
