Trisun is one professional manufacturer of mechanical seals interchangeable with John Crane, Burgmann, AES, Flowserve, Roten, Fluiten, Sealtek etc.
The 7K mechanical seal is BIDIRECTIONAL and is characterized by a short axial length. It allows both internal and external mounting, even against pressure just like type 7. It is manufactured in all steels, special alloys, hard facings and hard metals, solid silicon carbide. We always advise the mounting details of the seal plate of the conditions under which the seal is operating. It is ideal with high or pulsing counter pressure or with viscous or sticky fluids.
