Diaphragm Valves Resilience Diaphragms

Introduction
Saunders® develops, compounds and manufactures all single piece elastomer and 2 piece leaf style PTFE faced diaphragms inhouse from raw ingredient and has front to back ownership of all phases of development and manufacturing.

NEW! Type ER Resilience EPDM Diaphragm
Saunders® ER grade diaphragm is manufactured from a specially formulated EPDM compound. The ER material is peroxide cured for optimum cross linking and to minimize extractables and leachables.

Key Features
1. Reduction in cold flow deformation typically associated with conventional PTFE components present in BioPharm systems
2. Improved performance under aggressive steam sterilization and pure water-based media
3. Fabric reinforced EPDM backing

Type PR PTFE/EPDM Diaphragms
Key Features :
1. 100% virgin PTFE product contact face which is inert
and unaffected by media common to bio-process
applications
2. Industry conforming low levels of extractables and
leachables
3. Fabric reinforced EPDM backing

Key Features
1. Enhanced surface finish integrity to assist process purity (ASME BPE compliant)
2. Up to 40% improvement in compression set characteristic compared to typical EPDM diaphragms to reduce need for re-torque and ensure seal to atmosphere
3. Excellent chemical resistance to typical Biopharm process media
4. Front to back technology ownership optimizes security & reliability
