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.
