Ukuthwala impompo yamanzi sisixhobo esisetyenziselwa ukuxhasa ukuphela kwe-shaft impeller shaft yamanzi. Ukufakwa ngokukhuselekileyo kwi-shaft ye-impeller kunye ne-int tightly int

o indawo yempompo yamanzi, umbhobho wempompo wamanzi uyilelwe ukuba umelane noxinzelelo kunye nomthwalo obekwe phezu kweshafu yempompo yamanzi ngesixokelelwano sokuqhuba ibhanti le-injini. Kwiimeko ezininzi, umthamo wempompo wamanzi uhlawuliswa ngokwenza umsebenzi ophindwe kabini njengento yokuthwala i-impeller shaft ejikelezayo kunye nesitywina ukuthintela ukupholisa ekuvuzeni ngaphandle kwendlu yempompo yamanzi.
