After over 25 years of working together, Ashton Seals Ltd were delighted to announce our new Silver Distribution Agreement with Vulcan Seals in August 2025.
Vulcan seals are high-quality mechanical sealing solutions designed for demanding industrial environments. Known for their durability and precision engineering, Vulcan mechanical seals are widely used across industries including chemical processing, water treatment, food production and heavy engineering.
What Are Vulcan Seals?
Vulcan seals are mechanical seals and sealing components designed to prevent leakage in rotating equipment such as pumps and mixers.
They typically consist of:
- Rotating and stationary seal faces
- Elastomer seals (O-rings or bellows)
- Metal components for structural support
These seals create a tight sealing interface that prevents fluid leakage while allowing shaft rotation.
Vulcan Seals is a globally recognised manufacturer, supplying mechanical seals, encapsulated O-rings and gasketing solutions worldwide.
