● Cartridge Seal & Single Seal
● Independent of Direction of Rotation
● Balanced
● Spring Product Protected

BGM518 series mechanical seals are fully preassembled units ,which solve the problem of the man-made installation error. The multi-springs don’t contact the medium, so avoid damp and fret. There is no the movement for “O” ring in the direction of the shaft in the design, so consumedly extend the “O” ring’s life. According to the different work circumstance, we can offer two kinds of seals as 518A-with flush hole and 518B-with bearing.


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


Operating Limits:
● Pressure: ≤2.5MPa
● Temperature : -40℃~150℃(Viton “O”ring); -40℃~150℃(Chemlast “O”ring)
● Lnear Velocity: ≤20M/S
