C2-Sewage Pumps DN 32 to DN 600 - 2008.pdf

Sewage Pumps for Municipal and Industrial ApplicationsPlanning GuideCeram C0 Technical dataDescriptionCeram C0 is a sprayable, solvent-free two-component polymer coatingsubstance with a ceramic basis for protecting our productsagainst corrosion when there is additional strong mechanical stress.CompositionSolvent-free epoxy polymer with solvent-free polyamine hardenerand various extenders.Properties- Tough and durable coating with high mechanical and chemicalresistance and very good abrasion strength.-Excellent wet adhesion and compatibility with cathodic corrosionprotection as single-layer coating on steel surfaces.- Very good adhesion to steel surfaces.- Replaces tar-containing coatings.- Cost-saving due to the long service life, low maintenance and easyreparability.- Tested by the “Bundesanstalt für Wasserbau” (Federal Institute forHydraulic Engineering) (BAW).- Solvent-free.- Hardened coating has a high-gloss finish.Stability tableFluid Temperature FactorMethyl-ethyl-ketone (MEK) +20°C 3Sodium hydroxide (5%) +20°C 1Sodium hydroxide (5%) +50°C 2Sodium chloride solution (10%) +20°C 1Hydrochloric acid (5%) +20°C 2Hydrochloric acid (10%) +20°C 2Hydrochloric acid (20%) +20°C 3Sulphuric acid (10%) +20°C 2Sulphuric acid (20%) +20°C 3Nitric acid (5%) +20°C 3Toluene +20°C 2Water (cooling/industrial water) +50°C 1Xylene +20°C 1Key: 1 = stable; 2 = stable, short-term; 3 = overflow-stable, immediate cleaning;4 = not recommended for direct contactTechnical dataDensity (mixture)Adhesion / steelASTM D 792ISO 46241.4 g/cm³15 N/mm²Impact resistance / strength DIN EN ISO 6272 9 JTemperature resistance:60°Cdry, long-termTemperature resistance:120°Cdry, short-termTemperature resistance: Depending on the fluid; on requestwet / liquidSolid content (mixture) VolumeWeight97%98%Stability tableFluid Temperature FactorSewage, alkaline (pH 11) +20°C 1Sewage, alkaline (pH 11) +40°C 1Sewage, slightly acidic (pH 6) +20°C 1Sewage, slightly acidic (pH 6) +40°C 1Sewage, strongly acidic (pH 1) +20°C 2Sewage, strongly acidic (pH 1) +40°C 3Ammonium hydroxide (5%) +40°C 3Decanol (fatty alcohol) +20°C 1Decanol (fatty alcohol) +50°C 1Ethanol (40%) +20°C 1Ethanol (96%) +20°C 3Ethylene glycol +20°C 1Heating oil/diesel +20°C 1Compressor oil +20°C 1146 Subject to change without prior notice 09/2007 WILO AG
