Teflon Bellow

Product Code: TB13   Mechanical Seal

Versatile Solutions for Corrosive and Hygienic Applications

DESCRIPTION

Teflon Bellow Mechanical Seals are specially engineered for demanding chemical and pharmaceutical applications where metal contact with fluid must be avoided. These seals are made with virgin PTFE (Teflon) to provide superior resistance to corrosive chemicals, aggressive acids, alkalis, and solvents. The flexible PTFE bellows ensure shaft sealing even under misalignment or shaft deflection, while the modular design allows interchangeability of seal face materials depending on media and operating conditions.

FEATURES
  • PTFE bellows offer exceptional chemical resistance
  • Non-metallic design – eliminates risk of metallic corrosion
  • Single acting, unbalanced type
  • Suitable for shaft misalignment compensation
  • Self-cleaning bellows profile – reduces clogging
  • Compact design for easy installation and replacement
ADVANTAGES
  • Excellent performance in highly corrosive and abrasive media
  • No dynamic O-rings – ideal for media with crystallization risk
  • Long service life due to inert material properties
  • Complies with FDA standards
  • Easy retrofit into standard stuffing boxes
