Corrosion Resistant Equipment

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.

Features

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.

Product lineup

Ceramic Pump ET-Series NGK’s ceramics specially developed for the chemical industry use is utilized which provides the highest corrosion resistance against almost all acids and organic solvents. Learn more

Ceramic Pump EZ-Series This centrifugal pump has no shaft seal, making it ideal for pumping liquids where external leakage is unacceptable. Learn more

Chemflow Pump EB-Series Wetted parts such as casing and impeller are thickly lined with PTFE, which provides outstanding corrosion resistance against all acids, alkalis, and organic solvents. Learn more

Ceramic Valves Excellent corrosion resistance to most acids and solvents, except alkalis, hydrofluoric acid, or fluorine compounds. No pitting or crevice corrosion, which can occur in corrosion-resistant metals such as titanium. Learn more

Chemflow Valves All wetted parts are lined with integrally molded fluoroplastic. Designed with no welds or bonded parts makes the lining highly reliable. Learn more

Vacuum Pump The main equipment consists of a liquid-sealed vacuum pump, gas ejector, and mechanical booster pump.
All gas contacting parts are made of highly corrosion-resistant materials, mainly ceramics. All gases except hydrofluoric acid gas can be suctioned. Learn more
