Original Abstract

The tested radiaxial pump shows the considerable pressure pulsations accompanied with the strong noise for the flow rates lower than 0.4QBEP. This fact makes almost impossible to determine experimentally the dependence of the specific energy on the flow rates close to shut-off point. Likewise, after relatively short running period the strong wear of blades occurs due to the cavitation damage.Original and modified designs of radiaxial pumps with the same design parameters will be used to demonstrate the above mentioned possibilities. First the disadvantages will be outlined and then possible solutions will be illustrated. Pump operation will be simulated by means of CFD software. Experimental characteristic curve is at disposal for the problematic pump.
