The energy free static mixer
PCM Dostam
With its simple design, the PCM Dostam is a static mixer that is easy to implement in your installation.
It does not require any energy to operate. The passage of the fluid through the mixer is made possible by the transfer pump located upstream of the installation.
PCM Dostam is recommended for homogeneous fluid mixtures without parts.
The key advantages of the PCM Dostam
- Ideal for homogeneous mixtures : water/syrup, drinking yoghurt, oils, flavourings, etc.
- Extended range : 5 models covering flow rates from 800 to 60,000 L/h.
- Low internal volume (0.2 to 12 L): minimizes waste and facilitates cleaning.
- Simple integration : easily inserts in-line, without modifying the piping.
- Flexible installation : in horizontal or vertical downward position.
- Energy saving : without motorization, works thanks to the upstream pump.
- Low maintenance : no moving parts, no wear parts (excluding seals).
How the PCM Dostam works?
The PCM Dostam is a motorless mixer that relies solely on the speed of the fluid to achieve a homogeneous mixture. It consists of a chain of fixed links inside a tube. This ingenious design allows different liquids—such as a base and an aroma—to be efficiently mixed without any moving parts.
3-Step Operation
- Progressive Division of the Flow
At each link, the fluid is divided into two sub-flows. - Alternating Rotation Effect
The links are oriented alternately at 90° left and 90° right, creating a spiraling motion that enhances internal mixing. - Optimization of Division and Rotation
The Dostam, with its 10-link propeller, generates 1,024 divisions and rotations. This high number of combined divisions and rotations ensures an even distribution of ingredients—resulting in homogeneous mixing.
It operates with upstream pumps that provide either:
- Continuous flow (e.g., Moineau™ technology)
- Synchronized pulsed flow (e.g., Dosys™)
Proper sizing of the mixer is essential to ensure sufficient fluid velocity, which is critical for achieving high-quality mixing.
