Ekucubunguleni izimboni nezindawo zokumbiwa kwezimayini, ukususa imigodi yokuqoqa kanye namathange okugcina kuyisidingo sansuku zonke. Kodwa-ke, ukusebenzisa iphampu evamile kulo msebenzi kuvame ukuholela ekuphathweni kwekhanda elibuhlungu, ngokuyinhloko ngenxa yokuthi ukuthola iphampu iqale ukusebenza uma udweba{1}}izakhiwo zebanga ezingezansi kungaba nzima kakhulu.
Amaphampu angaphezulu{0}}afakwe endaweni evamile ngokuvamile adinga amasistimu ayisisizi, ama-vacuum assist, noma ama-valve ezinyaweni ukuze adonsele udaka luye phezulu. Uma uketshezi luqukethe izinto eziqinile ezisindayo noma amabhamuza omoya avaleleke, lezi zingxenye zokuqala ziyavaleka, okubangele ukuthi iphampu yome futhi ishise ngokweqile. Iphampu ye-slurry emiswe kahle idlula le nkinga ngokuphelele ngesakhiwo esilingana nama-sumps namathangi ngaphandle kwezinkinga zokuqala.
Ukususa imfuneko yokuqalisa kwizibalo kwenza imisebenzi yezitshalo ibe lula kakhulu. Iphampu ingahlala ingenzi lutho lapho imali engenayo iphansi futhi iqale ngokuzenzakalelayo lapho amazinga oketshezi ekhuphuka, konke ngaphandle kwengozi yokubopha umoya. Lokhu kusetha kuphinde kuqede ama-valve engeziwe namapayipi ahlotshaniswa namasistimu okuqalisa, okusho ukuthi izingxenye ezimbalwa zivezwe odaka olubi.
Nakuba ukukhetha i-impeller alloy efanele kuvimbela ukuguga ngaphambi kwesikhathi, ukukhetha iphampu ehlanganisa ngokuqondile esakhiweni sokuqukatha yilokho okuqinisekisa ukudluliswa koketshezi okuzenzakalelayo, okungaguquki.
