  • The BSIV™ range of single cartridge mechanical seals has been designed as a value-for-money, high-performance sealing solution for general applications. Inventoried in SHS bellows materials. Other material combinations are available, including a full, solid alloy 276 bellows and gland arrangement in all ANSI sizes.

    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.Bsiv Metal Bellows Cartridge Seal AES Mechanical Pump Seal 0
