Mechanical seal-multiple spring which are availble in a wide varietyh of elastomers for handing practically every industril fluid. All components are held togther by a snap ring in a unized construction design and can be repaired easily on-site.
The BT-FN combines a spring loaded ceramic face with the tradition of the pusher mechanical seals, the competitive price and the wide range of application have made 155(BT-FN) a successful seal. recommended for submersible pumps. clean water pumps, pumps for domestic appliances and gardening.
