When you’re looking for an efficient and economical way of mixing fluids together in a pipeline, a motionless mixing device is the savvy choice. With no moving parts, these mixers use the energy of the flow stream itself to generate the mixing movement making it a cost-effective solution.

What is a static mixer?

In principle, a static or motionless mixer is simply a pipeline element that is a modern alternative to a mechanical stirrer. A static mixer is inserted into the pipeline to manipulate various liquids to combine, divide and recombine meaning that they can also be used for reaction processes as well as for straightforward mixing.

The use of this type of mixer will significantly accelerate both these processes for stable and accurate sampling and smooth injection, resulting in continuous, fast, efficient and cost-effective operation with repeatable results.

The benefits of motionless mixers

A static mixer, like those available from statiflo.com, can be tailored to the specific needs of industries including water and wastewater treatment, polymer and plastic fibre production and the petrochemical industry, with different types of mixers being designed to work at particularly low pressures, to mix and transport mass flows using a gas dispersal system or simply to work across a diverse range of installations.

There are a number of advantages to using static or motionless mixers for best results. Because they’re so efficient, the use of any chemicals can be drastically reduced and the formation of byproducts will also fall dramatically. Also, because there are no moving parts, mixing is optimised while eliminating the need for agitators, tanks and direct motive power.

Thanks to the way a static mixer works, energy consumption is also minimised because the energy required is extracted from the pressure drop in the liquid itself as it flows through the different elements. This drives down energy use and means that a static mixer can be fitted without compromising other pumps already in use.

As motionless mixers have no moving parts, they require no maintenance and they’re as simple to install as any piece of pipe. In fact, these types of mixers are generally available in standard pipe sizes for a seamless install. Best of all, a static mixer can be designed to meet the specific requirements of any application.
