● Single Seal & Unbalanced
● Independent of Direction of Rotation
● Elastomer Bellows
● DIN 24960


Mechanical seals of the BIA series have such characteristics as sample and compact structure, short size of the direction of the shaft, which are in common use. BIA series mechanical seals are the same with oil, water and other weak corrosive medium, and also are used to replace the framework oil seal of the high speed rotary equipment.

● Face Materials: Carbon Graphite / Silicon Carbide/ Tungsten Carbide/Metal Oxide
● Secondary Seal Components: NBR/VITON/EPDM
● Spring and Construction Materials: Stainless Steel


Operating Limits:
● Pressure: ≤1.0MPa
● Temperature : -20℃~140℃
