Multiple Spring Mechanical Seals | Vulcan Seals
Multiple Spring Mechanical Seals

This exceptional range of seals has been specifically designed to withstand the most challenging industrial duties, particularly in the chemical industry. To ensure unmatched performance, we have incorporated multiple phenolic resin impregnated Carbon materials (VCT1) as the standard choice for this range.

The multiple spring seals require less axial length to provide the required face closing forces, allowing for shorter seal working length designs. Unlike larger single spring designs, they exhibit minimal distortion at high speeds. This results in a consistently even closing face pressure on the seal ring, ensuring optimal sealing performance at all times.

Our multiple spring seals have:
• Improved design
• No awkward setting pieces
• Improved face loading values
• Superior material quality
• Improved reliability
