PRIMIX custom made static mixers are fully customized inline mixers that are totally adapted to the use and process flow. The static tubular mixers can be dimensioned for almost all volume flows, densities, viscosities and substance specific characteristics.

Static mixers – tubular mixer or motionless mixers


Static mixers – tubular mixer or motionless mixers are suitable for:

  • Liquids – mixing liquids
  • Mixable liquids, such as mixing water and alkali
  • Non mixable liquids, such as mixing water and oil
  • Liquid – gas mixing, such as water and CO2
  • Gas – Gas mixing, such as Flue gas and ammonia


Inline mixers for mixing liquids and gases during a continuous process

With the PRIMIX static tubular mixer you can create a homogeneously distributed mixing of liquids and gases in a continuous process. This takes place entirely without moving parts which means there are no extra power or mechanical elements required. For this reason static mixers are also called motionless inline mixers. The lack of moving parts makes the PRIMIX static mixers very low maintenance, and process-technically extremely safe components. Read more about the operating principle of the static mixer.

Simple to clean - static tubular mixers

A PRIMIX static mixer is very simple to clean in a CIP cycle and depending on the process requirements the process can be done totally sanitary/sterile/aseptically. For static mixers with demountable mixer elements the cleaning can be done outside the tube. This can be very useful when processing extremely viscous media. Read more about sanitary mixers >


Advantages of PRIMIX static mixers:

  • No moving parts (motionless mixer), gaskets and shaft seals
  • Low energy consumption
  • Maintenance free and no risk of leakages
  • Predictable homogenisation
  • Low investment and fast return of investment
  • The process can be scaled up
  • Tubular mixer is in-line with the process

In industrial applications liquids and gases are moved through pipelines. The energy needed for this, in the form of pressure, is generated by a pump or compressor. Static mixers are very often fitted into these pipes and the components that need to be mixed or dispensed are added to the main flow directly before the mixer. The static mixer uses energy for mixing the components. This energy emerges as a certain pressure drop across the apparatus and the pressure is maintained by the pump or compressor. Energy consumption can be a significant cost for a process. Besides the homogeneity PRIMIX also calculates the expected fall in pressure beforehand, so that an optimal design is created with a very favourable –indirect– energy consumption.

Motionless mixers are maintenance free

What happens to the maintenance schedule after placing a PRIMIX static mixer or heat exchanger inside a process? To be very honest there is no schedule. Because the well thought out and maintenance free design, PRIMIX do not need one. On the other hand service at PRIMIX is at the highest level. For possible future mixer adjustments or for the calculation of processes PRIMIX is more than happy to assist you.



Design static mixerIt’s all-in the design - mixer design

At PRIMIX design is more. It includes the engineering and thinking through the process with the client. Clearly defining the relevant parameters and where necessary daring to ask critical questions. This with the aim of obtaining maximum performance in the process . The intended design is entirely calculated in our own PRIMIX Dynamics software and afterwards is designed in SolidWorks® . The design instructions and calculations are based on strict criteria formulated in the current industrial design standards for high pressure devices. Read more about the PRIMIX design perspective.
