Abstract
The fully split cartridge mechanical seal assembly is comprised of two unitized self contained assemblies which fit together to form a unitized cartridge design. The assembly uses set screws to position the seal assembly to the rotating shaft or sleeve and slots in the gland to receive attaching means to a fixed stationary or chamber. The stationary components of the assembly include the following: a split stationary seal ring, a split stationary seal ring packing, springs set into apertures in the split gland, the split gland, the split gland gasket, gland bolts, a gland split gasket, and setting clips and screws. The rotating components include the following: a split rotary seal ring, split rotary seal ring packing, a split sleeve, the split sleeve packing, the sleeve bolts, cup point set screws, and sleeve split gasket. The fully split cartridge mechanical seal design eliminates the handling of a lot of loose, delicate, precise manufactured components and allows for very simple, easy and time saving installation with no measurements or guess work.
