PLYMOUTH, Mich.—Freudenberg-NOK Sealing Technologies' Simrit division has developed a diaphragm design for fluid handling applications like inkjet printers.
The design replaces the traditional polytetrafluoroethylene foil with a perfluoroelastomer layer. The FFKM layer is bonded to fluoroelastomer pump diaphragms to improve stroke length, reliability and durability.
The company's Sealing Technologies Process Seals also introduced a new family of PTFE radial shaft seals designed to withstand high temperatures, high speeds and increased shaft runout. The seals are part of the Simmerring Radiamatic HTS II EWS family of products.
The line is designed to offer industrial users an alternative to mechanical face seals. It combines a PTFE shaft sealing ring and flexible bellows element in one application.
