Usually, the normal rotational speed of pumps is defined by the electric drive system and the frequency of the power supply. It is the objective of this paper to investigate the correlation between pump efficiency and rotational speed. The design of the particular, single stage, centrifugal pump and the test facility for the investigation of pump hydrodynamics with increasing rotational speed are presented in this paper. The original impeller design duty speed is 2850 rpm. Pump characteristic measurements of this impeller were performed for a speed range up to 9.000 rpm and it turned out that the best static pump efficiency at 9000 rpm is 3.7 % higher than the efficiency at 2000 rpm.
