Ukuthwala impompo yamanzi yithuluzi elisetshenziselwa ukuxhasa ukuphela komsele wompompi wamanzi. Ukulingana ngokuphepha eduze kwe-shaft ye-impeller kanye ne-int int

o izindlu zamaphampu wamanzi, ukuthwala kwempompo yamanzi kuklanyelwe ukumelana nengcindezi nomthwalo obekwe phezu kompompi wamanzi ngohlelo lwenjini lokushayela ibhande. Ezimweni eziningi, ukuthwala kwempompo yamanzi kukhokhiswa ukwenza umsebenzi ophindwe kabili njengesibambiso ses shaft esijikelezayo kanye nophawu lokuvimbela isipholisi ekuvuzeni endlini yempompo yamanzi.
