Pure-Fuse diaphragm technology incorporates a one-piece design that eliminates product-trap areas between the outer piston and diaphragm that can harbor bacteria. The patented design also provides an unbroken fluid-contact surface for clean-in-place (CIP) capability and reduced contamination risks. The diaphragm combines food-grade plastics and elastomers with a stainless-steel core without adhesives or nylon fabric that can contaminate process fluids in the event of a breech. By eliminating the outer piston, the diaphragms experience reduced abrasion. They are constructed of food-grade Wil-Flex (Santoprene), which meets all FDA CFR 21.177, EHEDG, 1935/2004/EC and 3-A requirements.
