The Alfa Laval ALT top-mounted agitator is suitable for atmospheric and pressurized tanks and comes in a range of sizes. The modular design and sizing options means you won’t have to invest more than needed and can look forward to optimal power consumption. ALT agitators are designed for easy CIP and can also be configured for use in sterile/aseptic and ATEX-certified applications.

Alfa Laval ALT top-in agitator

Excellent levels of hygiene for a wide range of cost-effective, tank-based blending and mixing duties

  • Easily tailored to meet specific tank/process requirements – modular design with hygienic materials increases flexibility and optimizes operation
  • Reduced energy consumption – unique impeller design and product heat absorption makes ALT up to 400% more efficient than impellers with standard pitch
  • Hygienic design and smooth surfaces meet EHEDG, USDA, FDA and 3-A standards
  • Operates at low speeds without reducing pumping capacity – up to 80% less power consumption compared with conventional impellers
  • High productivity – low wear and low maintenance (For instance, no dismantling or tank entry required to replace long-life seals and bearings)
We offer versions for sterile/aseptic applications and optional equipment, including welding flange, blind flange, cover for motor/gear and spare part kit, for all ALT top-mounted free-hanging agitators. ATEX certification and material certificates are available on request.

Come funziona:


Based on a modular design, our ALT agitators consist of a drive unit with bearing frame, free-hanging shaft with special shaft seal and specially designed energy-saving airfoil (EnSaFoil) impellers with two or three blades.

An electrical drive motor transmits the energy required for mixing and blending (directly or via a gearbox) to the agitator shaft. The shaft rotates, turning the EnSaFoil impellers. The impeller movement creates a high flow with low shear due to the highly effective axial pumping effect on the liquid in the tank. This results in effective mixing and blending of the entire contents of the tank.


Efficient agitation adds to the mix
