The pump for a commercial aircraft had an existing carbon face seal experiencing high leakage and seal failures. Technetics Qualiseal Technology was employed to find a solution.
High speed (27,000 rpm)
Dry running (no lubrication)
Determining Cause and Failure Modes
Seal testing and Qualiseal Technology FEA model indicated temperatures up to 650°F
Current secondary seal taking a set due to high temperature
Possible carbon resin exudation due to high temperature
Technetics Qualiseal Technology Solution
Designed a metal bellows seal assembly with a high-temperature carbon grade
Sealed application and satisfied extreme temperature requirements
A Legacy of Excellence
Today, with 13 primary manufacturing locations and more than 1,000 employees globally, the Technetics Group has grown to be the leading manufacturer and designer of sealing and critical component solutions, including sub-systems and assemblies, in the world.
