SAUNDERS TFM Diaphragms

The SR grade diaphragm is suitable for typical applications in the bioprocess industries such as Compendium Waters, buffers, CIP and SIP, protein solutions and other products. The SR diaphragm is especially recommended for applications subjected to intermittent steam service.
Saunders® EX Endurance Diaphragm features twopiece 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.
