Less metal, less corrosion: Savino Barbera chemical pumps industrial mixers solve an age-old problem

If you have to pump aggressive liquids, mix industrial water, transfer hazardous acids, or handle corrosive chemicals, then Savino Barbera pumps and mixers may be the perfect solution.

Savino Barbera equipment is made of acid-resistant plastic. As a result, there are no metal parts in direct contact with aggressive liquids. When handling hazardous fluids or industrial liquids, the main hazard is usually corrosion. This is why Savino Barbera has replaced most of the metal with plastic and protected the few components that have to be made of metal for mechanical support with chemically inert material. All the wetted parts of pumps and mixers (those that come in contact with liquid) are made of thermoplastics or coated with technical polymers, making them impervious to aggressive chemicals.

The main corrosion-resistant plastics used to manufacture this industrial equipment are PP, PVC, and PVDF. Further, the modular concept of these custom-made products enables us to supply machinery suited to numerous non-standard systems or applications.

The construction materials used on non-metallic products are selected based on the characteristics of the corrosive liquids treated. Savino Barbera takes great pride in its ability to choose the most appropriate thermoplastic material for each job. To determine which plastic is chemically compatible with the liquid to be pumped, it is necessary to understand the chemical and physical characteristics of the liquid to be handled. Every plastic material has a different chemical compatibility with the various corrosive liquids. The fundamental liquid data for selecting the material for wetted parts of the pump and mixers are: chemical nature, concentration, temperature, specific weight, and the possible presence of solids.

Of course, Savino Barbera plastic pumps and industrial mixers are compatible with countless corrosive chemicals (ferric chloride, hydrochloric acid, sodium hydroxide, chromic acid, sodium hypochlorite, phosphoric acid, brine, nitric acid, and hydrofluoric acid). But one of the most typical corrosive substances you can handle with these pumps and mixers is sulfuric acid.

Savino Barbera thermoplastic equipment is available in a range of different construction variants, allowing successful installations in widely varied industrial processes. And normal maintenance requires no special skills or abilities, simplifying daily work and turnarounds.
