The seat ring of the spare seat may be provided with a short tail or pin to block the seat and prevent seat rotation. BT-FH is a kind of seal, which is suitable for the application of machining metal parts for mechanical seal under the working conditions of pump. Seals range in diameter from 10 mm to 100 mm and have standard diameters specifically designed for chemical applications.This kinds of seal is featured of Single pusher-type seal, Unbalanced, Conical spring and Dependent on direction of rotation. We suggest that the o-ring seal we produced, are suitable for the industry, such as Chemical industry, Building services industry, Centrifugal pumps, Clean water pumps, etc.
