• Robust Drive Lugs: Engineered with reinforced drive tabs to handle the higher torque and break-out friction often associated with dirty water applications.
• Thermal Resilience: TC handles rapid temperature fluctuations (thermal shock) better than ceramic or some SiC grades, preventing face crazing.
Key Features
• Heavy Duty Upgrade: Replaces standard Silicon Carbide (SiC) or Carbon faces with solid Tungsten Carbide (TC) for Grundfos industrial pumps.
• Shock Resistant: Tungsten Carbide is significantly tougher than SiC, making it the ideal choice for systems prone to water hammer, vibration, or frequent start/stops.
• Dirty Water Ready: Resistant to fracturing from solid particles or debris impact, extending seal life in non-potable water applications.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
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
District Heating Network: Heating pumps were failing due to pipe scale and rust particles cracking the standard SiC seals. We upgraded them to this Tungsten Carbide type. The TC faces crushed the scale without damage, solving the chronic failure issue.
Testimonials
We use the TC seals for our industrial washdown pumps. They take a beating and keep running.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Why choose Tungsten Carbide over SiC?
A: While SiC is harder, it is brittle. Tungsten Carbide is much tougher and less likely to chip or crack if the pump cavitates or passes solid debris.
