Wilden Pure Fuse

Pure-Fuse Diaphragms for Hygienic Applications

By Tencarva Machinery Co., September 6, 2016

Grand Terrace, CAFebruary 26, 2016 Wilden®, part of PSG®, a Dover company and a worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to introduce Pure-Fuse Diaphragms that offer superior cleanability and higher performance for hygienic applications.

Pure-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 exceptional clean-in-place (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 greatly reduced abrasion, which results in longer diaphragm life.

An additional benefit of Pure-Fuse diaphragms compared to other cleanable diaphragms is the use of a large integral piston and full-stroke shaft that provide greater efficiency. This full-stroke configuration also allows the pump to achieve twice the dry vacuum and flow when compared to shorter-stroke CIP-capable diaphragms.

Wilden Pure-Fuse 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 outstanding 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).
