Agitators and Mixing Systems
Systems designed to ensure homogeneous mixing, dispersion, emulsion or suspension depending on the type of product.
Benefits
- Customized engineering based on viscosity, density, and rheology.
- Sanitary design and easy maintenance.
- High-efficiency motors with hygienic-grade mechanical seals.
- Integration with PLC and control systems.
Functionality / Applications
Types of agitators
1. According to the design of the impeller (propeller / mobile)
a) Marine propeller
- High efficiency
- Axial flows → ideal for mixing low viscosity liquids
- Widely used in food, chemicals and water
b) Turbines (Rushton, Pitch-blade, Hydrofoil)
- Rushton: strong turbulence, gases and dispersion
- Pitch-blade: axial flow, robust mixing
- Hydrofoil: high energy efficiency
c) Anchor
- For highly viscous fluids
- Scrape the tank walls
- Widely used in paints, cosmetics, gels
d) Helical propeller or helical tape
- For extreme viscosities
- Smooth but high-torque mix
e) Rotor–Stator (Homogenizers)
- High shear
- Emulsion and dispersion
- Used in pharmaceuticals, cosmetics, dairy
2. According to the type of movement
a) Axial
- Move the fluid from top to bottom
- Ideal for clear and uniform liquids
b) Radial
- Flow to the sides
- Ideal for mixtures with solids, gases, or dispersions
c) Tangential
- Circular flow
- Good suspension in tanks without baffles
3. According to the mounting position
a) Mixture of liquids
- Marine propeller
- Axial turbine
b) Dispersion of solids
- Radial turbine
- Rushton
c) High viscosity mixture
- Anchor
- Helical
d) Emulsification
- Rotor-stator
e) Suspension of solids
- Inclined turbines
- Hydrofoil
4. According to its structural design
a) Plates
- Metal plates stacked to form channels.
- High efficiency, compact and easy to clean.
- Used in food, pharmaceuticals and air conditioning.
b) Casing and tubes
- Tubes inside a cylindrical casing.
- Resistant to high pressures and temperatures.
- Common in chemistry, petrochemicals, and energy.
c) Air-cooled
- They use ambient air for cooling.
- They incorporate fins to increase surface area.
- Used in automotive and industrial refrigeration.
d) Concentric tubes
- One tube inside another.
- Simple, economical and for small flow rates.
5. According to the type of tank
a) With baffles
- Avoid tangential flow
- Increased efficiency
b) Without deflectors
- Rotating motion
- It requires specific agitators
6. According to power / speed
a) High speed
- Homogenizers
- Dispersers
- Rotor-stator
b) Low speed
- Anchor
- Helical
- Smooth blend
