RUBBER BELLOW SEALS

HG1

  • Rubber Bellows Drive
  • Interchangeable With MG1
  • Compact Fitting Length
  • Bi-directional

HG1 is a compact mechanical seal

for metric shafts, based on the industry standard "MG1" design. It is suitable for solids-containing media as

the bellows extend the full length of

the seal, protecting the shaft against

wear.

 

Metric shaft sizes and seat cavities

are standardised to DIN EN 12756,

except for the special compact fitting

length.

 

An optional "G6" o-ring mounted seat

is available.
