Double mechanical seals are sealing devices used in rotating equipment, such as pumps and mixers, to prevent leakage of fluids. They consist of two sets of seals arranged in a series, with a barrier fluid between them. The inner seal prevents leakage from the process fluid, while the outer seal provides additional protection. This configuration enhances reliability and extends the service life of the equipment by reducing wear and handling high-pressure and high-temperature conditions. Double mechanical seals are commonly used in industries where leakage could lead to contamination or safety risks.
George Cook developed the mechanical seal in the early 1900s. He designed the seal to address leakage issues in rotating equipment like pumps. His invention replaced traditional packing materials. It offered a more efficient solution to prevent fluid leakage. It also maintained the integrity of the rotating shafts. A mechanical seal is a device used … Read more
