• Electropolished Metal: All wetted stainless steel parts are electropolished to reduce surface roughness and improve corrosion resistance.
• Flush Connection: Integrated flush ports allow for steam quenching or water flushing to keep the faces clean and sterile.
Key Features
• Sanitary Cartridge: A fully pre-assembled cartridge seal designed for hygiene-critical applications. Features 99.5% Alumina Ceramic faces for optimal cleanliness.
• CIP/SIP Ready: Engineered to withstand the thermal shock of Clean-In-Place (hot acid/caustic) and Sterilize-In-Place (steam) cycles.
• Smooth Geometry: External contours are designed to be self-draining and free of crevices to prevent bacteria accumulation.

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
Juice Production: A fruit juice plant experienced seal failures due to the acidity of orange juice concentrate. We installed this Alumina Ceramic Cartridge. The ceramic face was unaffected by the citric acid, and the cartridge design simplified their maintenance swaps.
Testimonials
Hygiene is non-negotiable for us. These ceramic cartridges are easy to clean and approved by our quality control department.
