Product Overview
A bellows seal is a type of mechanical seal where a metal or elastomeric bellows replaces conventional springs. Its primary functions are to:
Provide axial compliance—compensating for shaft misalignment or endplay
Keep internal parts isolated from corrosive fluids like hydrochloric acid (HCl)
Ensure dependable sealing in aggressive chemical services Applications & Suitability for HCl
Perfect for corrosive and toxic fluid handling, including dilute or concentrated HCl, due to PTFE or ceramic wetted parts .
Found in centrifugal and chemical pumps, mixers, and reactors used in chemical processing plants .
Proper elastomer and face material selection is crucial to avoid rapid corrosion or degradation—e.g., PTFE or Viton elastomers with SiC faces are recommended.
Advantages
No exposed springs—critical for strong acid service
PTFE and ceramic wetted parts ensure broad chemical resistance
Self-aligning via bellows mechanism improves seal life
