Since 1967, Technetics Group has designed and produced a wide range of mechanical seals, engineered for the most demanding and varied rotary shaft applications. Our seals provide extended life and low leakage while accommodating high speeds, large axial movements and high pressures in both dry and wetted applications.

About Technetics Group Mechanical Seals

Technetics Group is a mechanical seal manufacturer with a wide variety of mechanical seal types including:

  • GULLIVER® mechanical seals for use in a wide variety of common industrial applications
  • CEFILAC GPA® mechanical seals for extreme applications with high levels of abrasion, corrosion and clogging
  • Carbon face seals for critical applications with high temperatures and high speeds
  • Qualiseal for when standard seals are inadequate, and applications require custom dimensions, high temperatures, special liquids, abrasive liquids and solids, pressure reversal, limited space, dry friction and more
  • Customized dynamic sealing solutions for applications where problems cannot be addressed by standard mechanical seals

Product Features

  • GULLIVER® Mechanical Seals
    Ideal for proper sealing of rotating parts, GULLIVER® mechanical seals are easy to assemble and provide long-lasting durability. They are an economical and dynamic sealing solution because of their excellent reliability and cost ratio, as well as their prevention of shaft wear. Technetics Group’s expertise in the field of elastomers helps provide innovative solutions for the secondary sealing of mechanical seals, adapted to the most varied operating conditions.
