• Material Certification: ATEST 3.1 provided for requested parts as per EN 10204.
• Designed for Nitrocellulose Deacidation: Specifically optimized for precision and efficiency in critical chemical processes.
• Basket Construction: Built from duplex stainless steel (DIN – WSt.-Nr 1.4462) for exceptional durability.
• Slotted Screens: Manufactured from the same high-grade duplex stainless steel for superior performance.
• Internal Wet Parts: Constructed from corrosion-resistant stainless steel (DIN – WSt.-Nr. 1.4571 / AISI 316Ti).
• Certified Components: All wet parts are certified to 3.1 EN 10204 standards.
• Substitution of Non-Available Parts: Purchased parts not available in stainless steel (DIN – WSt.-Nr. 1.4571 / AISI 316Ti) are replaced with equivalent materials, such as DIN – WSt.-Nr. 1.4305 (AISI 303).
• External Dry Parts: Made from structural steel with protective coatings or stainless steel (DIN – WSt.-Nr. 1.4301).
• Protective Coatings: Non-stainless steel components (e.g., stator, drive) are coated with high chemical-resistant paint.
• Non-Metallic Components: Teflon PTFE/FEP/PFA (for rotary and static seals) or PVDF (for wipers) used for components in contact with the working medium.
• Polished Surfaces: Wet surfaces are ground or electrochemically polished to Ra <= 0.8 μm for optimal smoothness and hygiene.
