Mining environments are among the most demanding for sealing technology — abrasion, high loads, dust, water ingress and aggressive chemicals all attack seals. FITCO supplies heavy-duty O-Rings and sealing components for mining equipment across Africa, India, GCC and UAE.
Mining Sealing Challenges
- Extreme abrasion from mineral slurries and dust
- High-pressure hydraulic systems in excavators and drill rigs
- Acidic mine water and chemical leaching solutions
- Wide temperature extremes from surface to underground
- Continuous heavy-duty operation requiring long seal life
Recommended Materials
- HNBR — Superior abrasion resistance; excellent for hydraulic mining equipment
- NBR — Hydraulic oils and general lubricating fluids
- FKM — Chemical processing and leaching circuit equipment
- EPDM — Water-based slurries and process water systems
Applications
- Hydraulic excavators, dump trucks and drilling rigs
- Slurry pumps and centrifugal pumps
- Conveyor belt tensioning and idler seals
- Ore processing and flotation cell equipment
- Mine dewatering pump seals
- Ventilation and compressed air systems
