Acid baths are used in a variety of industrial manufacturing processes. Examples are the circulation of etching baths, surface treatment and the cleaning of wafers. The pump housings must use acid-resistant materials such as PVDF. Our M-Series is ideal for conveying highly aggressive and toxic liquids due to its hermetically sealed magnetic coupling. The low-wear SiC mechanical seal is used in acidic applications, such as etching of printed circuit boards. Kreiselmatic is a specialised supplier of centrifugal pumps for the conveyance of high-purity and aggressive media.
