Stainless steel 1.4408 (G-X 6 CrNiMo 18 10) is a cast steel which is resistant to corrosion and acids and which is frequently used for fittings and pump casings because of its good general chemical stability. This material in a precision lost-wax casting is used for the wetted housing parts of the CHEMICOR series. The lost-wax process is a complex casting process yielding a smooth and dense surface with increased resistance to corrosion. The housing parts are additionally glass-bead blasted and pickled. The polished version is subjected to three additional machining stages, namely grinding, mechanical polishing and electrolytic polishing.
Cast polyamide PA 6 G is used for the center blocks. It displays very good mechanical strength and can withstand temperatures up to 130°C.
The materials PTFE and EPDM are used for ball valves and diaphragms of the ALMATEC metal pumps.
