Kalrez® Spectrum 7275

Product Overview

Kalrez® Spectrum 7275 is a premium perfluoroelastomer (FFKM) O-ring specifically engineered for highly aggressive oxidizing chemical environments, particularly in the pulp and paper industry.
The product delivers exceptional chemical resistance, reliable sealing performance, and extended service life, helping manufacturers minimize equipment failure and optimize maintenance costs.

In paper mills, chlorine dioxide (ClO₂) is widely used as an effective bleaching agent for pulp. However, this strong oxidizing environment poses significant challenges to conventional sealing materials. Kalrez® Spectrum 7275 is designed to reliably withstand these harsh conditions.

Applications in the Pulp & Paper Industry

Kalrez® Spectrum 7275 is ideally suited for pumps and equipment in direct contact with chlorine dioxide in aqueous solutions, including:

• Chlorine dioxide pump systems
• Piping and equipment for oxidizing chemical handling
• Pulp bleaching processes in paper mills
• CIP systems involving strong oxidizing chemicals

Typical operating environments:

• Chlorine dioxide (strong oxidizing agent)
• Water and cleaning solutions

Key Advantages of Kalrez® Spectrum 7275

Compared to standard FFKM sealing solutions, Kalrez® Spectrum 7275 offers superior performance:

🔬 Outstanding resistance to chlorine dioxide
⏱ Extended MTBR from approximately 5 months to over 12 months
🔧 Significantly increased pump seal service life, reducing repair frequency
📉 Reduced downtime and maintenance costs
