Wilden: Pure-Fuse diaphragms for hygienic applications


Wilden_Pure-Fuse-DiaphragmPure-Fuse diaphragm technology incorporates a one-piece design that eliminates product-trap areas between the outer piston and diaphragm that can harbor bacteria, a critical consideration for hygienic applications. This patented design also provides an unbroken fluid-contact surface for CIP capability and reduced contamination risks. Pure-Fuse combines food-grade plastics and elastomers with a stainless-steel core using no adhesives or nylon fabric that can contaminate process fluids in the event of a breech. In addition, by eliminating the outer piston Pure-Fuse diaphragms experience reduced abrasion, which results in longer diaphragm life.

These diaphragms are constructed of food-grade Wil-Flex™ (Santoprene™) that meets all FDA CFR 21.177, EHEDG, 1935/2004/EC and 3-A requirements. Wil-Flex features wide temperature limits, excellent flex life, high abrasion resistance and durability, even when handling acids, caustics and other aggressive fluids.

Pure-Fuse diaphragms are available in 25 mm (1″), 38 mm (1-1/2″), 51 mm (2″) 76 mm (3″) sizes with a temperature range from -40°C to 107°C (-40°F to 225°F).
