Alfa Laval ALT Top-Mounted Agitator Benefits
- Energy efficient design
- Reduce speeds without reducing pumping capacity
- Extensive fluid dynamic studies
Energy efficient design
Our EnSaFoil impellers, as well as our particularly designed EnSaFerm impellers for fermentation applications, reduce energy usage and heat absorption by your product. Based on rigorous fluid dynamic studies, their distinctive design allows them to be up to 400% more efficient than regular pitch impellers. Aside from lowering energy loss, our impellers function at lower speeds without sacrificing pumping capacity. When compared to agitators with traditional impellers, they reduce agitator power usage by up to 80%.
Modular and hygienic
When it comes to a variety of mixing and blending tasks in processing tanks, Alfa Laval agitators guarantee top-notch sanitation. Agitator systems can be easily customized to match the unique needs of each tank and process thanks to its modular design and use of sanitary materials with smooth surfaces. These materials adhere to a variety of standards, including those set out by EHEDG, USDA, FDA, and 3-A.
Simplified service
Alfa Laval agitators are characterized by low wear and little maintenance, which translates into increased output due to reduced downtime. Long-life seals and bearings may be replaced without removing or entering the tank, saving both time and money.
Product range
Four different Alfa Laval agitator models for top-, bottom- and side-mounting are available for installation in pressurized and non-pressurized tanks. Sterile/aseptic and ATEX-certified versions are available upon request.

Dimensions
Standard propeller diameter range: ø125 mm to 1900 mm. Specific dimensions on the drive unit and propeller(s) will depend on the actual configuration selected.
Construction
Based on a modular design, Alfa Laval agitators consist of a drive unit with bearing frame, shaft with special shaft seal arrangement, and bi- or tri-lobe energy-saving airfoil impellers.
Operating principle
An electrical motor (drive unit) transfers the energy required for mixing and blending to the agitator shaft, either directly or through a gearbox. The shaft rotates, propelling the specifically designed Energy Saving Foil impellers. The impeller movement produces a high flow with little shear because of the extremely effective axial pumping impact on the liquid in the tank. This results in a thorough mixing and blending of the tank’s contents.
Optional equipment
Alfa Laval also provides agitator types for sterile/aseptic applications, as well as optional equipment such as welding flanges, blind flanges, motor/gear covers, and spare part kits for its agitator line.
