Abstract: The contribution is aimed on the analysis of Y(Q) characteristic of centrifugal pump. The main attention is concentrated on the impeller of high specific speed, especially on the diagonal pumps. It is derived, that stability of Y(Q) curve depends on the dissipative function. The analysis concludes that very important is the design of the interior of spiral case and distributor to achieve a stable Y(Q) characteristic curve.
