Key Features

• Grundfos Specific Upgrade: A direct replacement for Grundfos H-type, A-type, or B-type seals, specifically upgraded with Tungsten Carbide faces.

• Ideal for Dirty Water: While standard Grundfos seals often use SiC, TC is preferred for applications involving dirty water or frequent start-stops where shock loads occur.

• Exact Shaft Fit: Precision-machined to fit the unique stepped shafts (12mm, 16mm, 22mm, etc.) of Grundfos CR, NB, and TP pumps.

Q: How do I know if I need Tungsten Carbide or Silicon Carbide?

A: Use Silicon Carbide (SiC) for general clean water and chemicals due to its hardness and low friction. Use Tungsten Carbide (TC) if the system has pressure shocks, vibrations, or contains heavy particles that might chip brittle SiC faces. TC is less likely to fracture under mechanical stress.
