2 They are also applicable forpositive suction heads below 0,5 possibility to employ Pumps of this seriesof different materialswith uniform dimensionsexchangeable SIHI standard componentsand of the same performance characteristicsin particular for liquids at the boiling point has led to broadapplication in pumping ofcondensatedistillaterefrigerantLPG andboiler feed inchemical plants, as well asdistillation columns in the beverage industrythe Pumps of this series have been frequently of the CEH .. / 7 series with retaining stage for levelcontrol of the liquid in the pump (protection against dry running)are specially applied for handling liquids under vapour pressure,also from underground of the series CEH are horizontal, self-priming sidechannel Pumps of handling gas along with the liquid, insegmental type construction with open vane wheel impellers.

3 Toobtain favourable NPSH values the CEH pump combines one ormore side Channel stages with a specially designed centrifugalsuction stage programme comprises 6 sizes each with 1-8 stages. Theexisting material designs allow optimum rating for therespectively desired performance range and the of the series CEH .. / 7 are equal to the CEH series,but equipped with retaining programme comprises 6 sizes with 2-7 stages. Thehydraulic components used in both series origin from our sidechannel pump assembly of prefabricated pressureMax.
