Deeply rooted
in the pulp and paper industry
In addition to the well-known Alpine peaks, forests are the main feature of Austria’s landscape. It is not only tourism that is a logical consequence of these geographical conditions. Austria has a long tradition in forestry, which has led to a strong pulp and paper industry.
Five million tons of paper are produced annually in Austria.
If output is measured in relation to the domestic consumption of paper and cardboard, Austria is actually the third largest paper-producing country in the world. This leads to a high concentration of paper machines and pulp mills, as well as plant engineering companies. With our headquarters in Graz, we are represented in the heart of this region and are therefore closely connected with them.
No paper machine and
no pulp mill
without Flowtec
More than 30 years ago, Flowtec founder Bedo Coc began his work in the pulp and paper industry. For over 20 years, Flowtec has been supplying end customers and supporting plant engineering and construction companies. Whether fine paper, tissue, packaging board or paper recycling – in 30 years we have built up comprehensive know-how relating to the processes and requirements of paper production and pulp technology.
It is therefore not surprising that Flowtec products are now represented in almost all of the plants of the 24 Austrian producers. In our sales region, more than 60 customers in the paper and pulp industry rely on our valves and our know how as well as our partners in the area of plants, machines and systems.
Able to withstand
the toughest conditions
Whether special sticky, acid or alkaline resistance in the digester, a high degree of contamination and abrasive media – the pulp and paper industry places high demands on the robustness and wear resistance of valves, systems and components. Over the years, we have established a partner network that allows us to offer products specifically developed for the industry and develop individually tailored solutions if required.

Long live the junk trap!
At Flowtec, we look for clean solutions: Dirt sluices are subjected to exceptional stresses in paper treatment. In our view, this is not a place for weak links. That’s why we rely on a particularly robust design with a long operating life: The Orbinox Junk Trap – the right connection for dirty business.
We are here for you.

Paper is not just paper.
Not just in its application,
but also in the production process.
From cardboard and graphic paper to fine and special paper – the paper types and their areas of application are as varied as the different production specifications.
As a long-term partner in the paper industry, we know that this does not only require a wide range of valves. Due to the large production range within a factory, the plants often need to be flexibly adaptable. This is only possible if the valves also cover a large application and adjustment range.

This way you get a regulated and uniform headbox
Our winning formula
for top quality and planning certainty.
The required basis weights must be strictly observed in order to achieve the appropriate material quality in stock preparation. That’s why in stock preparation we rely on valves that demonstrate a high degree of precision and reliability in all shut-off and control tasks, such as filler dosing or consistency control.
In pulp dewatering, the fibre type and length is a decisive factor that we take into account in order to recommend an appropriately designed valve because this is the only way to avoid fibre bundles and therefore quality defects and waste or production loss.
In the area of waste paper, interfering contaminants like paper clips, sand, plastic or glass residues often lead to classic malfunctions, for example, caused by jamming, wedging or blockages. In order to avoid unplanned stoppages in reject handling, we service.

Cost-effective
and economical.
Plant engineering and construction teams are faced with very different requirements in paper production depending on the end product, but all sectors have one challenge in common: abrasiveness. Titanium oxide (TiO2) or calcium carbonate (CaCO3) reduces the resistance of valves, especially in the production of special paper. Wear-resistant valves through to fully ceramic models or special coatings are used here to achieve better durability and therefore extend the service life.
In addition to high-quality, durable products, our range also includes inexpensive valves that ensure cost-effectiveness and efficiency even when the maintenance strategy involves the regular replacement of valves in highly abrasive environments.
