FH ALLUMINIUM OXIDE / SILICON CARBIDE + VITON

General features

Single pusher-type seal
Unbalanced
Conical spring
Dependent on direction of rotation
The FH is a seal for demanding applications where operating conditions in the pump require machined metal parts for the mechanical seal.
The seals are available in a full range of diameters from 10 to 100 mm and in the standard diameters specifically for chemical applications.
