Static mixers SMI™ and KVM™

Efficient mixing for turbulent flows

The Sulzer static mixers type SMI and KVM are ideal for liquid-liquid mixing in the turbulent flow regime. These mixers can also be used for mixing gases.

Main benefits
  • Low energy consumption due to small pressure drop
  • Excellent mixing
  • Fast and cost-efficient solutions due to standardized design
  • Efficient mixing of additives injected upstream
  • Multiple additive feed possible
  • Wide variety of materials available, also for highly corrosive fluids
Main applications
  • Mixing of turbulent flows (liquids or gas)
  • Refinery
  • Oil and gas
  • Chemical industry
  • Fiber industry
KVM mixer

The KVM mixer features a pressure drop of only 11’’ of water column at 5 ft/sec. It can mix additives introduced upstream of the mixer or mix additives injected directly in front of the first mixing element. In order to allow the injection of multiple additives, the KVM mixer can also be supplied with multiple injection port connections. The KVM mixer allows mixing of additives without a sparger.

The geometry of both mixer types has been optimized with the help of CFD simulation. The mixing elements create large counter rotating vortices and ensure efficient mixing over the entire cross section of the pipe. The static mixer type SMI is mainly sold in Europe and Asia, whereas the KVM type is the standard product for the North and South American market. The SMI mixer has an open structure, which eliminates the risk of clogging.

Its key characteristics are:

  • Appropriate dosing options
  • Simple construction
  • Low pressure drop
  • Efficient mixing within a short distance
