Type 7K

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, hard metals, and silicon carbide. We always advise the mounting details of the seal plate for the conditions under which the seal is operating. It is ideal with high or pulsing counterpressure or with viscous or sticky fluids.
