Centrifugal pumps for corrosive media
The Affetti factory has been producing plastic centrifugal pumps for transporting corrosive media for 35 years. Today, they ship their products to 45 countries for various applications, like: Sulphuric Acid (H2SO4), Hydrochloric acid (HCl), Sodium Hypochlorite (NaOCl), Nitric acid (HNO3), Caustic Soda (NaOH), Phosphoric acid (H3PO4), Ferric Chloride (ZnCl2), etc.
The Affetti monobloc or long coupled pumps are strong, produced in their components with high thickness to give a product with the maximum reliability. Primary label mechanical seals combinations are installed (internal, external and double flushed).
The Affetti centrifugal monobloc magnetic drive pump has been designed to solve the different problems generated sometimes from the leakage through the mechanical seals, with the consequence to cause serious environmental contaminations.
The Affetti vertical centrifugal pumps are easy to handle, the pumps of this range are strong, compact construction, produced in their components with high thickness to give a product with the maximum strength. Pump shaft connected to the motor through the elastic coupling with inside ball bearings, is guided through PTFE CG and Al2O3 (alumina) bushings; available upon request is the alternative combination in SiC-SiC (silicium carbide)
The Affetti Vitrum line was developed for mildly to severely corrosive liquids and able to withstand arduous working condition. All wetted parts are in reinforced fiberglass material, in order to resist abrasion and severe temperatures. The flexibility through a wide range of materials selections for corrosive and abrasive liquids is a distinction of Affetti Pumps.
