5 Guide to material and hydraulics selection for individual pumped liquids Amarex KRT The table below is intended as a guide for selecting pump materials and hydraulics and is based on many years of KSB experience. The data given in the table is intended as a recommendation / guide only. or more detailed information, please consult your nearest KSB sales office or ask for expert advice from the KSB advisory departments. Take advantage of the extensive KSB laboratory know-how when selecting pump materials.

Suitable for neutral, slightly aggressive media and media unlikely to cause excessive wear. The ph value of the pumped medium should be ² 6., sand content ± 0. g/l. Duplex Steel Cast Stainless Steel (1.17 or a technically equivalent material) The resistance to pitting of this ferritic-austenitic stainless cast steel makes it particularly suitable to pump sewage containing substantial amounts of chlorides and acids or sea- and brackish water. Its good chemical resistance, even against sewage containing phosphorus and sulphuric acid, has ensured its wide application in the chemical and process industries. Pumps made from duplex steel have been used very successfully to pump brine, chemical effluents (ph 1 12), foul water and seepage from waste disposal sites. Wear resistant White Iron (JN3 029 or a technically equivalent material) A wear resistant white iron for highly abrasive media, such as liquids containing sand, ashes or scale. Its hardness is approximately 61. to 68 Rockwell and therefore higher than hardened chromium steel. The alloyed cast iron of chromium- molybdenum has a significantly higher resistance to wear than cast iron JL 0 (GG-2) or other cast materials.
