Uchungechunge lwe-DG oluhlukaniswe izigaba eziningi lwephampu oluyi-centrifugal lusebenzisa amabhawodi e-tension ukuxhuma indawo yokungena amanzi, ingxenye ephakathi nendawo kanye nengxenye yokuphumayo ibe umkhiqizo wonke.Isetshenziswa emanzini okuphakelayo kubhayela nakwamanye amanzi ahlanzekile okushisa okuphezulu.Lolu chungechunge lunezinhlobo eziningi zemikhiqizo, ngakho lunohlu olukhulu lwezinhlelo zokusebenza.Futhi, inokusebenza okungcono nokusebenza kahle okuphezulu kunezinga elimaphakathi.
