Saunders® EX Endurance Diaphragm features two-piece leaf-type construction.
The diaphragm consists of a wetted modified PTFE face with a non-wetted fabric reinforced Silicone backing cushion.
The Silicone backing offers exceptional resistance to high temperatures compared to EPDM. EPDM rubbers suffer damage with prolonged exposure to temperature such as encountered during heat sterilization. This damage results in loss of resiliency and resistance to compression set and reduces the ability of the EPDM backing to properly energize the wetted PTFE diaphragm face.
Outstanding high temperature performance and resistance to long term exposure at elevated temperatures and ideal for steam distribution and supply, sterile barrier, and block-and-bleed applications.
Improved seal-to-atmosphere performance and reduced requirements for re-torqueing of fasteners after thermo cycling.
