• Non-Sparking: Carbon faces are non-sparking, making them safer for handling flammable solvents than metal-to-metal contact.
• Heat Dissipation: The low coefficient of friction generates minimal heat, preventing the vaporization of volatile chemicals at the seal face.
Key Features
• Chemical Plant Standard: A versatile cartridge seal featuring premium Carbon Graphite faces for broad chemical resistance.
• Inert & Self-Lubricating: Ideal for solvents, light acids, and non-abrasive chemicals where lubricity is poor. Carbon survives dry starts.
• Impregnated Grades: Available with Resin or Antimony impregnated carbon to tailor chemical resistance and hardness to specific aggressive media.

Industry Solutions
Case Study
Solvent Recovery: A plant recycling acetone faced seal failures due to the low viscosity fluid causing face heat. We installed this Carbon Cartridge. The self-lubricating carbon ran cool, preventing flashing and extending MTBF by 200%.
Testimonials
We standardized on this Carbon/SiC cartridge for all our clean chemical services. It's forgiving, reliable, and cost-effective.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Can I use this for caustic soda?
A: For strong caustics (high pH), standard resin-carbon may degrade. We recommend upgrading to Sintered SiC vs. Sintered SiC faces for caustic service. Carbon is best for acids, solvents, and neutral fluids.
