Steel and stainless steel pickles

The pickling of metals for corrosion protection is carried out to remove surface layers such as oxides (e.g. scale, rust) by chemical or electrochemical treatment. During this process, the pickles are loaded with metallic ions and solids, which require renewal of the pickling, separation of the solids or recycling of the pickling liquid.

In the field of conveying the different pickling liquids Rheinhütte Pumpen has extensive practical experience, which is additionally based on the results of our own investigations.

The unique variety of materials offers various approaches to solutions for the pickling of metals. Due to the good resistance of plastics to the common media in pickling plants, PP and PE are suitable pump materials. In addition, under certain conditions the use of PVDF, PFA / PTFE, SIGUSS or 1.4517 is also suitable. Our materials experts have acquired the competence through many years of experience to find the right pump material even for difficult media.
