M2N/M3N/M37G series of mechanical seals, simple structure, wide application, good reliability. Suitable for clean water pump, sewage pump, submersible pump and chemical process pump, etc.

The M2N series mechanical seal has a graphite rotating ring. Mainly suitable for circulating pump and heating system with water medium, static ring can be selected G4, G6, G9 and other forms. M3N series of mechanical seals, the rotating ring of the integral alloy or silicon carbide, simple structure, wide application, good reliability. Suitable for clean water pump, sewage pump, submersible pump and chemical process pump, etc. When the moving ring adopts Mosaic friction ring, its type is called M37G type.
