RUBBER BELLOW SEALS

HG1S20

  • Rubber bellows drive
  • Shaft protection
  • Independent of direction of rotation
  • To suit Euro-metric dimensions

HG1S20 is to suit European installation requirements. It is a rubber bellows mechanical seal which is friction-driven by an elastomer bellows. It provides protection to the shaft over the entire seal length, and is insensitive to shaft deflections due to large axial movement ability. Recommended for duties containing media with solids etc.

 

Pump-specific and / or modified versions of HG1S20 exist, usually to a custom working length.
