Saunders EX Endurance Diaphragm

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.

The EX Silicone backing can handle these same elevated temperatures with no deterioration of physical properties.

The Saunders Endurance Diaphragm is also ideal for applications that require service at unusually high temperatures. The EX Diaphragm has been tested on continuous steam at 175DegC (347DegF).

  • Outstanding high temperature performance and resistance to long term exposure at elevated temperatures
  • 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
