NGK Chemitech's corrosion-resistant equipment has an extensive track record in various industrial fields where high corrosion resistance is required.

NGK’s first ceramic centrifugal pump
Centrifuge Pump 1933

NGK Chemitec offers pumps, valves, and lining equipment that utilize ceramics and PTFE for the chemical industry with excellent corrosion and heat resistance.
NGK Chemitech has a long experience in processes requiring high corrosion resistance, such as petrochemicals, commodity chemicals, steel, pharmaceuticals, and fine chemicals.

NGK ceramic chemical pump was developed as early as 1933 shortly after company’s foundation in 1919 and has served various industries since then.


  • High corrosion and heat resistance

    NGK-developed ceramics for the chemical industry has outstanding corrosion resistance to most acids and organic solvents (except alkali, hydrofluoric acid or fluorine compounds), and are not deformed by heat. PFA (Perfluoroalkoxy alkanes) has outstanding corrosion resistance to all acids, alkalis, and organic solvents, with no elution of organic matter or ions.

  • Wide range of products

    We offer a wide range of Ceramic lined and PTFE lined pump and valves.

  • High reliability

    Based on our rich experience in the field of corrosion resistance, we provide equipment that is maintenance free for a long period of time, contributing to lower running cost.
