Metal Bellows

Style 40 - 42 - 45 - Welded metal bellows.

  • Dynamic O-ring is eliminated.
  • Superior performance, no hang up or shaft fretting.
  • Hydraulically balanced seal. Allows seal to handle more pressure without heat buildup.
  • Pressure to 300 PSI.
  • Self cleaning. Centrifugal force throws solids away from seal.
  • Fits small cross section stuffing boxes.
  • Available in metric and DIN sizes.
  • Bellows allows 360 degrees even face loading.
  • Varied choice of face, elastomer, and metal materials.
  • Single piece construction.
