About Us.

Cavex® is your trusted brand for hydrocyclones, backed by the vast network of Weir Minerals Services™

Our innovative range of Cavex® hydrocyclones provides excellent classification efficiency and hydraulic capacity as well as maximum feed chamber wear life.

How we got to where we are now ?

In 1996, a team of engineers from Warman International in Australia got together to develop the ‘next big thing’ in hydrocyclones. What they came up with was revolutionary.

The truly unique Cavex® inlet geometry removed all sharp angles from the feed chamber, allowing slurry to move through the hydrocyclone smoothly, which greatly reduced wear while increasing its efficiency. The new generation of hydrocyclones easily delivered up to three times the wear life of the old technology. The streamline feed chamber is still in use today.

A myriad of improvements have been incorporated throughout years of development to ensure the hydrocyclones continue to provide excellent wear life. Along with advanced lining technology for ultra-heavy duty applications the Cavex® hydrocyclones withstand the demands of high volume abrasive materials.

Today, there are more than 26,000 Cavex® hydrocyclones operating across the globe, making up more than a quarter of the global market share. Every single one of these hydrocyclones is backed by the extensive Weir Minerals service team.
