Description

Sanitary Pressure Relief

Pure-Gard is a welded sanitary pressure relief solution specifically designed for applications where cleanability is of paramount importance. The new disc design provides a cleanable, robust solution to address the challenges of complex manufacturing environments including pharmaceutical, biopharmaceutical and food.

Crevice and dimple free design

Pure-Gard meets industry expectations for cleanability with its crevice and dimple free design. It meets FDA and ASME BPE requirements, and is CIP/SIP compatible. Our rigorous testing program includes dye penetrant testing and helium leak testing.

Structural stability

The one-piece design protects the rupture disc, avoiding the risk of damage at the point of installation. Pure-Gard’s structural stability also means its performance is unaffected by vent-side pipework loads.

Extended product life

Pure-Gard provides a solution independent of the gasket, allowing regular change of gaskets without needing to change the disc. This innovative design feature extends the life of Pure-Gard beyond conventional sanitary pressure relief solutions.

Reusable modular detection

Pure-Gard is designed for use with our Vent-Tel burst detection system, which is an independent, reusable and non-invasive solution. The Vent-Tel is mounted directly to the Tri-Clamp, making disc inspection and replacement quick and simple.
