● Single Seal & Unbalanced
● Elastomer Bellows
● Independent of Direction of Rotation
● DIN 24760


Mechanical seals of the BGM108 series are drove by the interference of the elastomer bellow, which have such characteristic as simple and compact frame, steady-going performance, convenient installation,etc. BGM108 series mechanical seals are the same with oil, water and other weak corrosive medium. By mounting two back-to-back rotary seats, the BGM108 mechanical seal can be changed into BGM208 double seal mechanical seal, which normally is used in the deep-well pump.


Materials for Mechanical Seals:
● 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: ≤1.0 MPa
● Temperature : -20℃~140℃
● Linear Velocity: ≤10M/S
