Abstract

Den foreliggende oppfinnelsen vedrører en sentrifugalpumpe for å pumpe væske omfattende forurensning, hovedsakelig i form av faststoffpartikler, hvor pumpen omfatter en drivenhet og en hydraulisk enhet, idet den hydrauliske enheten omfatter et pumpehus (20) og et pumpeskovlhjul (12) som er roterbart anbrakt inne i huset. Pumpeskovlhjulet omfatter en øvre (14) og en nedre (16) dekselskive og et antall mellomliggende skovler (18). Oppfinnelsen er karakterisert ved at bunnveggen (22) til pumpehuset som har en sentral innløpsåpning (24), er arrangert med minst én spiralmessigutstrekkende tilbakestrømningspåvirkende måte (32, 34) på siden som vender mot den nedre dekselskiven, som strekker seg delvis eller fullstendig rundt innløpsåpningen.
