The BMI series comprises a range of vertical agitators with direct drive. They can be used in mixing, dissolution, dispersion, and maintenance processes requiring strong agitation at high speeds, as well as in the food processing, cosmetics, and chemical industries, selecting the appropriate finish in each case.
Applicable to tanks with capacities of up to 10,000 litres, usually with low viscosity products.
Operating principle
The agitators are usually installed off-centre to prevent product rotation but can also be installed centred in conjunction with deflector baffles in the tank.
The rotating propeller pushes the product towards the bottom of the tank, where it is diverted generating an upward flow along the tank walls so that the product reaches the surface of liquid. This effect is enhanced if the tank has a rounded base.
