This patent describes a double mechanical seal system that is particularly intended for abrasives and other harsh applications. In order to provide cooling flow circulation close to the seal faces, a series of axial grooves are machined in the shaft sleeve. The design also provides a drive or anti-r

โฆ Synopsis
This covers a gasket similar to that described in WO/2009/060689. In this case the sheath is described as PTFE or inorganic sheets that are laminated and bonded to the thin metal plate of core material. It is, again, claimed to work with both low and high compression forces. Large deformation of the sheet is controlled and thinner PTFE sheets (12, 13) or inorganic sheets can be used by preventing the low fluidity PTFE sheet or inorganic sheet from being broken even if a high fastening load is applied.
