ATEX Mechanical Seals
ATEX sealing solutions for hazardous environments
Where flammable gases, vapours or combustible dusts are present, equipment must be designed to operate safely and reliably. In these environments, selecting the correct mechanical seal is critical.
RB Mechanical Seals manufactures and supplies ATEX-rated sealing solutions for pumps, mixers and agitators operating in hazardous areas. We support customers across the chemical, pharmaceutical, food production, brewing, water treatment, biogas and agricultural sectors where reliability and compliance are essential.
Whether you require a new seal, refurbishment of an existing seal or a complete sealing solution, we can help identify the most suitable option for your application.
What IS ATEX?
ATEX refers to regulations covering equipment intended for use in potentially explosive atmospheres.
A potentially explosive atmosphere exists when flammable gases, vapours, mists or combustible dusts mix with air and can ignite under certain operating conditions.
These hazardous environments are divided into different zones depending on how often an explosive atmosphere is present. The correct selection of mechanical seals and supporting equipment is essential to maintaining safe and reliable operation.
We can supply sealing solutions suitable for ATEX Category 2 applications, including Zone 1 and Zone 21 environments.
Why ATEX matters
In hazardous areas, a mechanical seal is more than simply a wear component. It forms part of the equipment’s overall safety system.
Incorrect seal selection can lead to excessive heat generation, premature wear, loss of containment and reduced reliability. Selecting the correct sealing arrangement helps maintain safe operation, minimise downtime and protect both personnel and equipment.
Every application is different, which is why we assess operating conditions carefully before recommending a solution.
ATEX Pump Seals
We manufacture and supply ATEX-rated pump seals for a wide range of industrial applications.
Our seals are used on centrifugal pumps, progressive cavity pumps, hygienic pumps, wastewater pumps and specialist process equipment handling everything from chemicals and solvents to sludge, digestate and process liquids.
Each application is reviewed individually to ensure the correct seal design, materials and operating limits are selected for the duty.
ATEX Mixer and Agitator Seals
Mixers and agitators create unique sealing challenges due to shaft movement, vibration, vessel pressure and varying process conditions.
We manufacture ATEX-rated mixer and agitator seals designed to provide reliable performance in hazardous environments where both safety and uptime are critical.
Our sealing solutions are used on a wide range of equipment, including Winkworth, Chemineer, Silverson and Greeves, as well as older or bespoke machinery where OEM support may no longer be available.
ATEX Seal Support Systems
RB Mechanical Seals manufactures seal support systems in-house for applications where additional cooling, lubrication or containment is required.
A seal support system helps maintain stable operating conditions around the seal faces, reducing wear, improving reliability and extending seal life.
Our systems are built for demanding industrial environments and can be supplied for ATEX-rated applications. Manufacturing in-house allows us to maintain full control over quality, specification and build standards while providing a solution tailored to the equipment and process conditions.
ATEX Seal Repair and Refurbishment
Mechanical seals used in hazardous environments do not always need replacing when wear occurs.
We provide seal repair and refurbishment services for a wide range of mechanical seal types. Each seal is dismantled, cleaned, inspected and assessed before refurbishment begins.
Seal faces are re-lapped, worn components are replaced and the assembly is restored to the correct operating tolerances. Where refurbishment is not the most suitable option, we will recommend the best replacement solution.
Industries We Support
Our ATEX-rated sealing solutions are used across a wide range of industries, including:
Chemical processing
Pharmaceutical manufacturing
Food production
Brewing and distilling
Wastewater treatment
Freshwater treatment
Biogas plants
Agricultural processing
Bulk powder handling
Whether the equipment is handling solvents, chemicals, digestate, powders, vapours or combustible dusts, we can help identify the correct sealing arrangement.
Engineering Support
Every application is different. Before recommending an ATEX sealing solution, we review the equipment, operating conditions and hazardous area classification to ensure the sealing arrangement is suitable for the duty.
Where required, we can visit site, inspect the equipment and provide practical engineering advice based on real operating conditions rather than assumptions.
Our aim is simple: provide a sealing solution that operates safely, reliably and delivers long service life.
