Key Performance Advantages

Unmatched Chemical Inertness

Constructed primarily out of premium PTFE (Teflon) and GFT components, creating complete resistance against highly aggressive chemical degradation.

Outside Mounted Flexibility

Designed for external installation to avoid exposing critical metallic components or springs directly to volatile fluid media, maximizing service life.

Excellent Bellow Compensation

The convoluted Teflon bellow effectively compensates for minor radial shaft run-out, axial play, and variations caused by dynamic runtime adjustments.

Target Media & Applications

This specific Teflon Bellow Seal structure is highly recommended for handling:

  • Concentrated Acids (Nitric, Hydrochloric, Sulfuric)
  • Strong Alkaline Solutions & Caustic Liquors
  • Chemical Dosing and Pickling Line Pumps
  • Fertilizer Production Pipelines
  • Pharmaceutical Processing Ingredients
