What is a Mechanical Seal?
Featured Product from Technetics Group
Expertly Engineered Mechanical Seals by Technetics Group
Since 1967, Technetics Group has designed and produced a wide range of mechanical seals, engineered for the most demanding and varied rotary shaft applications.
With trusted brands such as QUALISEAL®, GULLIVER® and CEFILAC GPA®, we deliver extended life and low leakage while accommodating a wide range of sizes, speeds, pressures and temperatures in both dry and wetted applications.
What is a Mechanical Seal, and What Goes Into the Design?
The primary purpose of a mechanical seal is to separate air from fluids in rotating applications. Mechanical seals consist of a rotating component, a rotor or mating ring, and a stationary component often called the seal. Qualiseal® mechanical seal applications typically demand reduced leakage and seal longevity.
The core design consideration is a function of the system pressure and the surface velocity of the rotating component. Our engineers consider the limited physical space constraints, or envelope, the seal must be able to fit into. We review our customer’s main concerns, whether the leak rate or the seal’s life. When choosing the materials for the seal construction, the media the seal will be exposed to is an issue of utmost concern to the seal’s design.
