Static Mixer - Bespoke

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.

No moving parts (motionless mixer), gaskets, and shaft seals

Low energy consumption

Maintenance free and no risk of leakages

Predictable homogenisation

Basic features

Static mixers – tubular mixers or motionless mixers are suitable for:
  • Liquids – mixing liquids
  • Mixable liquids, such as mixing water and alkali
  • Nonmixable liquids, such as mixing water and oil
  • Liquid – gas mixings, such as water and CO2
  • Gas – Gas mixing, such as Flue gas and ammonia

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.

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.

Low energy consumption

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.


Static mixers have a very wide range of application within various kinds of industries and are therefore very flexible. In general applications such as technical homogeneous mixing, extraction, washing, reacting, cooling, mixing of viscous media and heating are the most common. But of course other less common applications are also possible. The various media to be mixed or treated are described under the menu item: industries, on the website.
