External mechanical seal - PC01
The M7N series is made of compact structure. It has a various application scope and high interchangeability. This series is widely used in petrochemical pumps. It is also embedded with drive collar that is clamped by the drive lug, in order to avoid the spring from dropping. The product is constructed with the combination of materials such as graphite, silicon carbide, tungsten carbide and aluminum oxide. Then, a secondary sealing of materials are acrylonitrile rubber, fluorine and silicon rubber.
It is also built with stainless steel. M7N series has its pressure ranging up to ≤2.5 Mpa with a temperature of -50220. The linear speed of this series reaches up to ≤20m/s.
