TYPE 8B1 MECHANICAL SEALS
High Quality Multiple Spring O-ring Mechanical Seals
Our mechanical seal model 8B1 can Replace AESSEAL M02S and CRANE 
8B1,
which is widely used for industrial pumps. 
 The normal material 
combination include resin carbon/ceramic/NBR/ss304,resin 
carbon/tc/nbr/ss304,sic/sic/NBR/ss304 ,tc/tc/NBR/ss304 and so on. we 
also can
 make changes as customers'requirement or totally design a new 
type of mechanical
 seal to meet clients'needs.
8B1 Mechanical seal-multiple spring which are availble in a wide variety 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.
High Quality Multiple Spring O-ring Mechanical Seals
Advantages: 
We offer multi spring unbalanced sealings which are used for general-purpose
petrochemicals,mining, chemical plants, water pumps, pharmaceutical factories,
 refrigeration, power stations, and shipbuilding.
For efficiency of unbalanced seal we use raw materials such as carbon, ceramic, 
TC, PTFE and so on.
The shaft fretting in the spring unbalanced seal is minimized to lower the spring
 loads provided through wedge or O rings.
Spring unbalanced seals or spring mechanical seal can be easily assembled from
 dismantled form through circlip.
It can be changed to balance version by simply merely by changing the carbon
 face and can be provided with single, double or tandem arrangement with external
 seal support systems & devices.
8B1 mechanical seals are available in a wide variety of elastomers for 
handling 
practically every industrial fluid. All components are held 
together by a snap ring
 in a unitized construction design. It is 
suitable for general industrial applications
 including refining, 
chemical processing, food and beverage, petrochemical 
processing, 
pharmaceutical, wastewater and power generation.
