Der Flash-Mode im wahren MenschenHigh viscosities (low Reynolds numbers) impair the pump performance. Liquids with up to ν = 3000 mm./s (3000 cSt) can be pumped with centrifugal pumps, but efficiencies drop to very low levels which make the operation highly uneconomic.

Der natürliche Mensch und sein ImpulssystemOperational problems can often be traced back to a non-optimum - or even downright wrong - pump selection. An unsuitable selection may result from insufficient knowledge of pump operation and installation conditions or from not giving them careful consideration and analysis.
