Mechanical Seal ASMS3 (Standard Bore)

Mechanical Seal ASMS3 (Standard)


  • Stationary springs and drive pin mechanism isolated from process fluids to minimize corrosion, clogging, and stress-related failures
  • Unique, metal-shrouded rotary seal ring for maximum face protection and uniform 360° transfer of torque to the rotating face during start up
  • Dynamic elastomer moves on non-metallic, smooth surface eliminating fretting
  • Stationary design for optimal face alignment
