Article: Expanded Use Of Split Seal Technology For Large Pumps And Agitators

By Scott Boyson, A. W. Chesterton Corporation

New advances in split mechanical seals have expanded its application for use in both water and wastewater systems. These systems move vast amounts of fluid through pipes and tanks. Water-based fluid systems comprise the largest fluid transport systems in the world with wastewater streams being the largest. While the systems' designs can vary by region, most use centrifugal pumps to move fluid. Many of the centrifugal pumps are very large and difficult to assemble, so they have not typically been sealed by mechanical seals which require total equipment disassembly. However, split mechanical seals have advanced so that these pumps can now be sealed without equipment disassembly.
