Abstract/Summary Centrifugal pump characteristics (i.e. specific energy gH, power P, and efficiency η curves plotted vs. flow capacity Q) at different pump operating speeds are important to the successful operation of pumps in various areas of chemical technology. In the present paper the pump characteristics are treated in a dimensionless form. The main advantage of this approach is the fact that only one characteristic curve is used for all possible operating speeds of the tested pump in the frame of suitable dimensionless numbers. Also, the obtained relation between dimensionless numbers allows to estimate the main pump characteristics in the case when the properties (ρ and μ) of the liquid were varied.
