Plastic makes these centrifugal pumps resist corrosives

| By Chemical Engineering

Since 1962, this company has been manufacturing horizontal and vertical centrifugal pumps to handle corrosive and abrasive fluids. The pumps are made of various thermoplastics (PP, PVDF, PE-UHMW, PFA, PTFE) or stainless steel (AISI 316, 316L, 904L and Hastelloy). The pumps can be equipped with mechanical seals or magnetic drives, and are machined in thick parts of plastic to make them robust. Most recently, the company has introduced the first centrifugal pump with thick parts made of PEEK (polyether etherketone), which offers temperature resistance of over 200°C and chemical resistance to solvents, acids, bases and more. The NP 80-50-200 pump (photo) is made of PVDF, with ATEX explosion-proof standards. This horizontal non-metallic pump is ISO 2858 standard. — Someflu, Bagnolet, France
