What is the difference between an inline emulsifier and a shear pump?
Inline Emulsifier An inline emulsifier is a type of high-shear mixer specifically engineered for emulsion formation, where two immiscible liquids (e.g., oil and water) are finely dispersed into one another. It achieves this through a rotor-stator system, where high-velocity rotors force materials through precision stator slots, creating intense shear forces and hydraulic cavitation. This process
Inline Emulsifier
An inline emulsifier is a type of high-shear mixer specifically engineered for emulsion formation, where two immiscible liquids (e.g., oil and water) are finely dispersed into one another. It achieves this through a rotor-stator system, where high-velocity rotors force materials through precision stator slots, creating intense shear forces and hydraulic cavitation. This process reduces droplet size down to submicron or nano levels, stabilizing emulsions with or without emulsifiers/surfactants.
- Oil-in-water or water-in-oil emulsions
- Cosmetic creams, pharmaceutical suspensions
- Food-grade sauces, dressings, and condiments
- Nanoparticle formation in biotech and chemical industries
Inline Shear Pump
An inline shear pump combines fluid conveyance and mechanical shear in one unit. It also utilizes a rotor-stator configuration but is designed primarily for viscous pumping with a secondary function of particle size reduction, dispersion, or homogenization. Unlike emulsifiers, shear pumps are optimized to transfer fluid under pressure while providing controlled shear energy, making them ideal for continuous processing systems with medium to high viscosities.
- Dispersion of powders into liquids
- Breakdown of agglomerates or soft solids in slurries
- Homogenizing viscous materials like polymers or adhesives
- Pumping shear-sensitive materials with uniform consistency
