Welded Metal Bellow Mechanical Seals MFLWT80
This advanced metal bellows seal is engineered for severe service applications involving extreme thermal cycling and highly viscous media. It provides reliable performance in:
• Chemical processing industry applications
• Oil and gas processing equipment
• Refining technology operations
• High-temperature pump sealing applications
• Aggressive chemical and hydrocarbon services
Product Detail
This balanced seal design features a compact configuration that reduces overall length while providing enhanced performance in high-temperature applications. The innovative bellows construction protects shaft and sleeve components from wear and scoring, with optimized notch geometry that eliminates stress concentration in the bellows plates. The stationary seal face complies with EN12756 (DIN 24960) dimensional standards for direct interchangeability.
