GRUNDFOS® MECHANICAL SEALS

HG2

  • Seal Code 'B-'
  • OEM Replacement
  • Suits Grundfos TP Series 100

HG2 replaces the Type "B-" code component seals typically fitted to Grundfos TP Series 100 - Vertical In-Line 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 KU.

 

The 12mm & 16mm sizes feature a Grundfos-design intermeshing rigid torque transmission system.

The 33mm size uses a traditional bellows along with a cup-mounted stationary. Fitted to larger 2-pole LP and NP pumps.
