Steel columns lined with POLYFLURON PTFE can be used for distilling, rectifying (evaporating, condensing), absorbing, quenching, washing or desorbing liquids or liquid mixtures. These liquids can be extremely corrosive media such as hydrofluoric acid (HF), hydrochloric acid (HCl), sulfuric acid (H2SO4), phosphoric acid (H3PO4) as well as their intermediate products and derivatives, which result directly or indirectly during their production or processing.

For more than 60 years, SGL Carbon has been designing centrifugal process pumps from its wide range of impregnated, impervious carbon and graphite materials. These materials offer an excellent corrosion resistance and an unmatched thermal stability at temperatures up to 200 °C.
SGL Carbon is offering a full product portfolio with international manufacturing standards compliance and customization possibilities of the massive base construction.
Distributed worldwide, these heavy-duty motor-pump groups ensure an extended service life and stand for an indisputable alternative to thermoplastic, metallic or ceramic pumps at our valued customer’s production plants.

In case of heat exchange of corrosive media, DIABON plate heat exchangers are first choice.
Plate heat exchangers are the most modern and efficient heat exchange technology on the market. They replace more and more traditional types like block, annular groove or shell & tube heat exchangers.
In cooperation between Alfa Laval and SGL Carbon plate heat exchangers made out of DIABON graphite are established.
More than 3000 references worldwide and continuous innovations like the world largest graphite plate heat exchanger type P90 are our proof of outstanding customer benefits.
