Industries & Applications

Water and Waste

We have full ranges of fluid sealing products that are well proven for long life with low maintenance in the water and waste sectors. In addition, our plant maintenance and refurbishment services are highly appreciated by utility companies.

Water and WasteA number of our sealing products are WRAS-approved for potable water applications. Some of these significantly reduce water companies' stockholding requirements, as they also have the abrasion and chemical resistance needed for wastewater processing and river intake duties.

The following is a selection of our relevant products and services...

All these provide long-term sealing with highly abrasive slurries and chemicals used in treatment processes.
