Metal Bellow Mechanical Seals

Hong Teng supplies metal bellows mechanical seals for selected high-temperature, chemical, process and industrial pump applications. Our range includes welded metal bellows seal designs for services where conventional dynamic elastomer movement may be unsuitable, with replacement options for selected industrial seal references.

Selection should be based on operating temperature, pressure, pumped medium, shaft size, seal chamber dimensions, face materials and bellows metallurgy. If the original reference is unavailable, send us the pump information, drawing, old seal photos or operating parameters for compatibility checking.
