Bulkhead Shaft Seals | HydroActive Technology

Bulkhead Shaft Seals are a critical piece of the propulsion safety equipment that stops cross compartment flooding following a compromising event keeping the ship and crew safe while continuo operation. Mide’s innovative line of non-contacting HydroActive™ bulkhead shaft seals provides an extremely reliable and low total ownership cost sealing solution. Developed for the US Navy, the patented design utilizes hydrogel embedded foam to engage and seal against the spinning shaft only when water is present. By not touching the shaft during normal operation the seal can withstand any shaft speed and substantial shaft motion without any wear - reducing maintenance costs significantly. Reliant YM The Reliant YM is a flagship seal design in which total system weight is reduced and maintenance is simplified through use of Midé HydroActive technology. Instead of a traditional housing, the Reliant YM series uses flat interface plates secured to the bulkhead, on which the seal floats, to allow for radial motions of the shaft. Reliant YM seals are installed and operating on many vessels. Reliant HD The Reliant HD series of bulkhead seals are used where large shaft motions, in excess if three (3) inches, are required. This configuration uses a large machined housing and cartridge style arrangement; while maintaining the benefits of HydroActive technology which allows the Reliant HD series seals to be deployed in the most challenging conditions. OMNI Omni seals bulkhead shaft seals are designed for vessels that don’t have the large shaft radial deflections typically required for naval ships. With fewer components, the non-floating Omni seals are significantly less expensive and easier to install and maintain.
