In the metallurgical industry, the aim is to improve and enrich metal surfaces through various treatments. These not only reinforce protection but also add functional features and offer aesthetic finishes. To achieve these goals, metal pieces are immersed in baths or tanks that, for the most part, contain corrosive liquids.
TECNIUM excels in manufacturing centrifugal plastic pumps, designed with robustness and with all areas in contact with the fluid made of fully compatible plastic materials. Our range spans from small pumps for specific transfers (1 m³/h) to those intended for large flows in industrial processes (1,200 m³/h).
Depending on the treatment applied to the metals, different liquids are used, such as hydrochloric acid, sulfuric acid, caustic soda, among others. One essential application in this sector is the recirculation of these liquids in treatment tanks to maintain a stable temperature and, sometimes, remove solid particles generated during processes like pickling.
After determining the flows, pressures, and working temperatures, our technical team selects the most suitable material for the task. We have extensive experience in manufacturing plastic pumps using materials such as PP, PVDF, PEHD (RCH1000), Halar, and PVC.
