Report covers research of one-stage volute pump KP06(C) (65/16) for company SPP Pumps Ltd. Measured head overall efficiency and NPSH curves are presented and briefly commented. Impeller modification by blade under-filing increased pump in whole range of operation by 6% while efficiency drop was 1.5%. New impeller into existing volute was designed using semi-empirical relations and CFD simulation. Maximus hydraulic efficiency, based on numerical results, achieves 90.6% and coincides with design flow rate. Head in the best efficiency point is 33 meters.
