The NBI series agitators are medium speed vertical agitators with geared motor.

These agitators can be used in processes of mixing, dissolution, dispersion, and maintenance whenever a medium or mild agitation of medium or low viscosity products is required in the food processing, cosmetics, pharmaceutical or chemical industries.

Operating principle

The agitators are normally installed inside the tank either centrally with current deflectors, or offset to prevent the rotation of the stirred product.

The rotation of the propeller makes the fluid flow to the bottom and then up to the surface of the product along the walls of the tank. The effect is promoted if the bottom of the tank is curved.
