• Energy Efficiency: Carbon's low coefficient of friction consumes less power than hard-face combinations, contributing to the overall efficiency of the pump system.
• Flexible Drive: The rubber bellows or O-ring drive mechanism absorbs minor shaft vibrations, protecting the brittle carbon face from fracture.
Key Features
• Grundfos Replacement: Replaces the standard "A-Type" or "B-Type" O-ring seals found in Grundfos TP, NB, and NK end-suction pumps.
• Optimized for Water: Carbon Graphite vs. Silicon Carbide (or Ceramic) is the ideal pairing for clean water circulation, HVAC, and pressure boosting.
• Quiet Operation: The low friction of Carbon faces ensures quiet, squeak-free operation, essential for pumps in residential or commercial buildings.

Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Office Building HVAC: Cooling pumps in an office block were noisy due to face vibration. We replaced the old seals with our Grundfos Carbon/SiC seals. The self-lubricating carbon silenced the noise and has run leak-free for 2 years.
Testimonials
We service hundreds of Grundfos TP pumps. These carbon seals are our standard stock item. Reliable and priced right for the repair market.
