Alfa Laval LeviMag® Mixers Introduction The Alfa Laval LeviMag® is an aseptic magnetic mixer that uses a patented levitating impeller and advanced design to mix down to the last drop and maximize product yield. Compact, energy-efficient and easy to maintain, it provides dry- running capabilities and efficient mixing at low speeds, which ensures gentle product treatment, as well as at high speeds for high-intensity mixing. This provides greater process flexibility to handle a wide range of fluid types and mixing duties. Its open design and low-speed rotation during cleaning contribute to effective residue removal and minimize contamination risks from wear particles. All this contributes to fast return on investment and maximum product yield in tanks ranging in size between 8 US gallons and US 10,567 gallons. It is supplied with Alfa Laval Q-doc, a comprehensive documentation package that provides full transparency of the entire supply chain. Applications Alfa Laval LeviMag magnetic mixer offers effective mixing for multiple processes in the dairy, food, beverage, biotechnology, pharmaceutical and other industries that have demanding requirements for sterile or aseptic storage or processing. Benefits • Maximum process efficiency, minimal product loss • Optimal flow with higher efficiency and less energy consumption • Mixing down to the last drop for maximum yield due to low agitation and dry-running capability • Optimized Cleaning-in-Place (CIP) due to full drainability • Minimized downtime due to ease of maintenance Standard design The Alfa Laval LeviMag consists of a detachable drive unit, levitating impeller unit with radial blades, seals, ceramic bearings and magnetic coupling, weld plate and connections. It is available in five sizes, with mixing speeds ranging from 10 rpm up to 800 rpm. Working principle An impeller with radial blades installed inside the tank rotates due to the torque from the magnetic coupling. The rotation of the impeller mixes the fluid inside the tank. The unique design of the Alfa Laval magnetic coupling ensures the levitation of the impeller at all times. This enables dry-running and complete drainability of process fluids from the tank possible. This ensures highly efficient mixing down to the last drop and, subsequently, maximum yield. It also enables the free flow of CIP liquid and steam around all parts of the mixer, thereby ensuring thorough cleaning. Impeller levitation also eliminates axial wear. Available versions • Impeller with male/female bearing • Impeller complete, with drive unit • ATEX version (Cat. II -/2G Ex h IIC T4 -/Gb) 26
