Water Lubricated Stern Tube Shaft Seals
Fully split, water lubricated mechanical face stern tube seals for military and commercial vessels, with optional HydroActive backup seal.
Description
Mide's water lubricated stern tube seals are an environmentally friendly mechanical face seal option for military and commercial vessels, in line with the EPA Vessel General Permit (VGP) regulations. They were developed with the US Navy for the LCS Freedom Class, where high shaft speeds and shock requirements caused problems for existing face seal materials. The design is fully split to reduce maintenance and replacement costs.
Key features
- Durable, ultra-low friction materials instead of brittle silicon carbide hard faces
- Operates at high shaft speed in blue or brown water
- Optional HydroActive backup seal that engages automatically if the main seal is compromised
- Fully shock qualified version for the Littoral Combat Ship
- 1,000 hour operational testing and MIL-STD-167 testing in development
Applications
Stern tube shaft sealing on naval and commercial vessels.
