Metallic materials of GMN seal components series L/M guarantee highest resistance against coarse and fine contamination.
Metallic materials are suitable for temperatures up to 200 °C.
The M design has grooves on the circumference which are used to remove and return penetrated liquid during heavy and direct spray impact.
Technical data:
The technical data for the M design is the same as for the L design.
Characteristics:
Frictionless: Thanks to their non-contact design, GMN labyrinth seals guarantee completely frictionless operation.
Wear-free: GMN seal components work completely wear-free and offer an unlimited service life.
Abrasion-free: The non-contact design of GMN seal components guarantees operation free from metal abrasion that fulfills the highest cleanliness requirements.
Effective: The small distance between the outer and inner ring of just approx. 0.2–0.5 mm guarantees a high sealing effect and highly effective protection from fouling.
Heat-free: Because no friction heat is generated, neither the seal nor the adjacent components or the lubricant are subjected to thermal loads.
Efficient: The frictionless design enables operation without performance losses. This means that the seal offers maximum sealing effect with reduced energy consumption even at high speeds.
Compact: GMN labyrinth seals achieve 2–4-layered labyrinths in the smallest space.
Effective: The low gap height creates an air cushion in the sealing gap at high circumferential speeds that increases the sealing effect.
Return: Drainage grooves on the outer ring return any penetrated liquids (M design).
