Wilden introduces Pure-Fuse diaphragms for hygienic applications

Wilden, part of PSG, a Dover company, has introduced Pure-Fuse diaphragms that offer high 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 harbour 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 breach.

In addition, by eliminating the outer piston, Pure-Fuse diaphragms experience greatly reduced abrasion, which results in longer diaphragm life.

The diaphragms also use 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, good flex life, high abrasion resistance, and great 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"), and 76 mm (3") sizes with a temperature range from -40°C to 107°C.
