GRUNDFOS® MECHANICAL SEALS

HG3

  • Seal Code 'B-'
  • OEM Replacement
  • Older Centrifugal Pumps

HG3 replaces the Type "B-" code component seals typically fitted to older Grundfos centrifugal pumps.

 

The bellows extend the full length of the seal, protecting the shaft against wear. Shaft and seal dimensions made according to DIN 24960 (EN 12756) version NU.

 

The 12mm & 16mm sizes feature a Grundfos-design intermeshing rigid torque transmission system. Fitted to older CR and TP Series 200 pumps.

 

The 22mm size uses a traditional bellows along with a cup-mounted stationary. Fitted to older LM, LP, NM and NP pumps.
