Agitators from PRT – So that everything is always well mixed

The chemical industry in particular has to deal with a wide variety of materials and liquids. These must be mixed regularly. This requires special agitators which are not only able to withstand different temperatures but also the different materials. We offer you a wide range of agitators for this purpose, which can be used in different areas. They can be used for simple mixing tasks, gentle mixing, but also for the mixing of strongly foaming media.

Waste water treatment by means of agitators

The possibility of waste water treatment with our agitators is only one of many possible applications. We also differentiate between geared agitators and manual agitators. Of course you also have the possibility to use our agitators in the laboratory to produce different solutions. Our various stirrers are driven by an electric motor, compressed air motor or even a hydraulic motor. They are infinitely variable and thus produce a mixture quickly.

Agitators stand for safety

Our agitators are in most cases also available according to ATEX. In case of explosive materials, our agitators can be used here without any problems. They contain an explosion protection. They are also safe to run dry and can run fast or slow, depending on the agitator. Thus the agitator can be individually adapted to the mixture. A particular advantage of our agitators is their changeability. We offer you a particularly wide range of products, which does not stop at agitators. Also oil separator conveyors, oil skimmers or pumps are part of our product range.
