MULTI-STAGE SIDE CHANNEL PUMP

摘要

The invention relates to a multi-stage side channel pump, the performance of which is optimized by adapting the geometry of each subsequent stage (14) to the specific volume of the medium at the level of the outlet of the preceding stage (12) by dimensioning of the impeller diameter (D) and filling diameter (d). The pressure is the same for both stages (12, 14). The impeller geometry of the subsequent stage (14) is determined by the volume ratio of preceding stage (12) to subsequent stage (14), assuming geometric similarity.
