Key innovation: The SMV™ geometry generates higher shear forces than conventional in-line mixing equipment, enabling efficient dispersion of immiscible phases with interfacial tension — including challenging gas/liquid and oil/water systems — while maintaining a short mixing length and low pressure drop relative to mixing performance. shear forces are adaptable by changing the pipe diameter to meet product requirements.

The SMV™ operating principle

1. Corrugated sheet geometry and cross-flow mixing
   The SMV™ mixing element is built from a series of corrugated metal sheets set at opposing angles within the pipe cross-section. As the fluid flows through the element, it is continuously split and recombined across the full pipe diameter, generating radial mixing without rotation or mechanical agitation. This static mixing technology is entirely driven by the energy of the flowing fluid — making it inherently low-maintenance and energy-efficient.


2. Interface renewal and mass transfer
   For gas-liquid contacting and liquid-liquid dispersion applications, the SMV™ continuously renews the interface between phases, dramatically increasing the effective mass transfer area per unit length. The resulting droplet or bubble size distribution is controlled by the shear forces generated at the element edge — enabling precise dispersion results that are consistent and reproducible across production runs. This makes the SMV™ the preferred static mixing technology for reactive absorption and extraction.

High mass transfer efficiency
The SMV™ continuously renews the interface surface area between phases, enabling fast and complete reaction, absorption, and extraction. The result is superior mass transfer efficiency in a short installation length compared to conventional in-line mixing equipment.

Effective laminar flow mixing
While primarily designed for turbulent regimes, the SMV™ can also deliver homogeneous mixing in laminar flow conditions for specific configurations, making it a versatile choice across a range of viscosities and flow rates. For dedicated high-viscosity laminar applications, Sulzer's SMX™ Plus static mixer is the recommended solution.

Zero maintenance and zero moving parts
With no rotating or dynamic components, the SMV™ eliminates mechanical wear, seal failure, and lubrication requirements entirely. This translates directly into lower total cost of ownership and higher process reliability compared to dynamic mixing solutions.

Compact footprint and low energy consumption
The SMV™ requires minimal installation space and uses only the pressure energy of the flowing fluid — with no external power input. High mixing efficiency combined with large turn-down capabilities makes it the benchmark Sulzer static mixer for high-throughput industrial processes.
