GRUNDFOS OEM REPLACEMENT SEALS

HGGD

  • Shaft seal only
  • Suits CR 2/4 pumps
  • Unbalanced, O-ring mounted
  • Rigid torque transmission

Robust o-ring seal feature a rigid torque transmission design required for hard material parings (WC/WC or SiC/SiC), even where lubrication is poor.

 

The dynamic secondary seal is an O-ring. This involves a risk of wear on the shaft under the O-ring and of seal hang-up (blocking of axial movement of the rotating seal ring).
