Amaphampu aphikisana nokugqoka ama-multistage centrifugal ezinhlelweni zokusebenza kwezimayini asetshenziswa kabanzi embonini yezimayini, ikakhulukazi ukukhipha amanzi angaphansi komhlaba kusuka emayini. Kunemodeli emibili esetshenziswa kakhulu: uhlobo lwe-MD oluvundlile lokugqoka okumelene ne-multipstage centrifugal phompo yezimayini, kanye ne-MDP yohlobo lokuzilinganisa ukugqoka okumelene ne-multipstage centrifugal pompu enokwakhiwa kokuzilinganisa. Kule ndatshana, uChangsha Zhonglian Pump Industry, umkhiqizi okhokhelwayo wamaphampu e-multistage centrifugal, kuzohlinzeka ngesingeniso esiningiliziwe ekukhethweni kwezinto nezinqubo ezikhethekile zokukhiqiza ezisetshenziswe kulolu lwazi lwamaphampu okubalulekile ukuqinisekisa ukusebenza okuthembekile nokwandisa impilo yensizakalo yemishini.
