BDFI & BDFC

Bellows Double Flow Induction / Convection

The BDFI™/BDFC™ (Bellows Double Flow Induction/Convection) is an innovative modular hybrid design, created using the inboard design of a BQFD™ and the outboard design of a DMSF™. 

With 50% more bellows than the industry standard (12 instead of 8) there is less stress on each convolution in the bellows stack which helps increase seal life. AESSEAL® standard bellows material, Alloy 276, has superior mechanical and corrosion resistance properties than other industry standard bellows materials such as 300 series Stainless Steel or Alloy 20. The hydraulically balanced bellows unit is available in a variety of different material options with either elastomer or graphite packing sealing rings.

Features: 
       

• Incorporates pumping ring to maximize cooling and increase seal life
• large 3/8" ports maximize cooling and extend seal life
• Integral deflector guides cooling barrier fluid to the most essential areas
• Sizes available from 1.000" to 5.000" (24mm - 125mm) in standard and ANSI Plus gland formats
