• Large Axial Movement Capacity: The deep-convolution bellow design allows for greater axial compensation (±3mm or more) to accommodate thermal expansion of the reactor vessel.
• Reverse Pressure Capability: Metal face seals are designed to hold pressure from either the process side or the barrier fluid side, ensuring safety during pressure fluctuations.
Key Features
• Reactor-Specific Design: Metal face seals are engineered to handle the significant shaft runout and deflection common in top-entry mixers and reactors.
• High-Alloy Construction: Features Inconel® 718 or Hastelloy® C-276 bellows to withstand aggressive chemical reactions and high temperatures.
• Gas or Liquid Lubricated: Available in dry-running gas seal configurations or wet-lubricated designs depending on process toxicity.

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 metal face 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
Pharmaceutical Reactor Upgrade: A pharmaceutical plant faced weekly seal failures on a glass-lined reactor due to shaft wobble. We installed the 10k27 metal face seals. Its high flexibility absorbed the runout, extending the seal life to over 2 years and preventing batch contamination.
Testimonials
Reactor seals are critical for safety. This 10k27 metal face seals model handles the vibration of our main agitator perfectly without leaking.

FAQs about Metal Face Sealss for High Temperature Pumps
Q: Can this seal handle dry running during tank emptying?
A: If configured with dry-running Carbon faces or as a gas seal, yes. Standard liquid-lubricated faces require a barrier fluid system (Plan 53/54) to survive dry running.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
