Water Lubricated Stern Tube Shaft Seals

Environmentally Friendly Water Lubricated Stern Tube Shaft Seals

Mide's line of stern tube seals, currently under development, are a 100% environmentally friendly mechanical face seal option for both military and commercial vessels.  The water lubricated system utilizes innovative materials, a fully split design, and an optional innovative backup seal to provide a robust, reliable and low maintenance cost solution that can operate at high shaft speed.

Midé’s water lubrication solution is in line with the Environmental Protection Agency’s (EPA) Vessel General Permit (VGP) regulations. Mide's Stern Tube Seals can also incorporate its HyroActive technology as a backup seal that automatically engages in situations where the main seal may be compromised - allowing the ship to continue to operate and return to a location where repairs can be performed.

Many high-performance mechanical face seals use silicon carbide (SiC) or other hard face seal materials which are difficult to work with and brittle.  Midé’s seals use innovative durable materials with ultra-low friction leading to superior wear properties, long life and thus reduced total ownership cost (TOC)….even in the harshest environments.  Blue water or brown water Midé’s shaft seals will perform.
