The technique and the algorithm of the determination of the main design parameters of the low mass centrifugal pump

The technique and the algorithm of determination of the main design parameters of the low mass flow rate centrifugal pump with semi-open impellers were presented in this paper. The leakage of the working fluid in the axial clearance of the pump and the hydraulic losses at the inlet to the impeller were taken into account in the above-mentioned method. The proposed method can be used for the design of the low mass centrifugal pumps.
