Performance analysis of PKM 60 peripheral pumps as a consequence of impeller wearing.

Abstract The efficient transformation of energy in pumping systems plays a fundamental role the industry, these represent significant consumption, if pumps present wear their impeller, they will significantly decrease capacity to communicate fluid, that other words, system require more compensate for this efficiency, causing an increase operating costs. This work presents comparison performance two identical with different impellers, new impeller and subjected wear, which has been emulated by machining its radial component. results show peak net height power communicated fluid 55% 63% respectively. percentages transfer obtained test are not equivalent percentage diameter reduction, presented from 56.5 mm 59.6 mm, 5.2%.
