• Sintered SiC: We use high-grade Sintered SiC for maximum hardness and chemical inertness, ensuring reliability in aggressive industrial effluents.
• Optimized Geometry: Designed to fit the specific "Griploc" or "Plug-in" dimensions of modern Flygt N-pumps.
Key Features
• Premium Upgrade: Upgrades standard Flygt seals to Silicon Carbide (SiC) faces for superior abrasion and chemical resistance.
• Heat & Chemical Ready: Paired with FKM (Viton®) bellows, this seal handles industrial wastewater containing chemicals or higher temperatures than standard NBR seals.
• Extended Life: SiC faces resist grooving from silt and grit, maintaining a leak-free seal 3-5 times longer than ceramic.

Industry Solutions
Case Study
Chemical Drain Sump: A chemical plant sump pump (Flygt 3153) was failing due to chemical attack on the NBR bellow and ceramic face. We supplied this SiC/FKM upgrade. It resisted the chemical cocktail and grit, solving the chronic failure.
Testimonials
We use these SiC/FKM seals for all our industrial customers. It turns a standard sewage pump into a light chemical pump.
