Single seal / Unbalanced / Independent of direction of rota-tion/ Rubber bellows

FBD mechanical seal series is uneasy to be blocked due to its single spring struture. It has advanced rotating ring float-

ability so that reduced compensational resistance. This series is suitable for oil, water and other weak corrosive medium.
