Ngokubhekiselele ekubeni kukho umthombo wamandla, yahlulwe ibe: akukho mthombo wamandlaimpompo yomlilo ((ibizwa ngokuba yimpompo),iyunithi yempompo yomlilo(ekubhekiswa kuyo njengeyunithi yokumpompa).

Nye,Iimpompo zomlilo ezingenamandla zingahlelwa ngokwemigaqo elandelayo

1. Ngokwethuba lokusetyenziswa, lihlukaniswe: iimpompo zomlilo zezithuthi, iimpompo zomlilo zaselwandle, iimpompo zomlilo zobunjineli kunye nezinye iimpompo zomlilo.

2. Ngokwenqanaba loxinzelelo lwe-outlet, lihlulwe libe: impompo yomlilo yoxinzelelo oluphantsi, impompo yomlilo yoxinzelelo oluphakathi, ipompo yomlilo ephakathi kunye nephantsi, ipompo yomlilo ephezulu kunye nephantsi.

3. Yahlulwe ngokusetyenziswa: impompo yomlilo yonikezelo lwamanzi, impompo yokucima umlilo yombane, impompo yokucima umlilo yolwelo lwamagwebu.

4. Ngokweempawu ezincedisayo, zahlulwe zibe: iimpompo zomlilo eziqhelekileyo, iimpompo zomlilo ezinzulu, kunye neepompo zomlilo ezingaphantsi kwamanzi.

2. Iiyunithi zempompo yomlilo zingahlelwa ngokwemigaqo elandelayo:

1. Ngokohlobo lomthombo wamandla, lwahlulwe lwaba:Iyunithi yempompo yomlilo ye-injini ye-diesel,Iyunithi yempompo yemoto yombane yombane,Iseti yempompo yomlilo ye-iturbine yegesi, iseti yepompo yomlilo ye-injini yepetroli.

2. Yahlulwe ngokusetyenziswa:Unikezelo lwamanzi iyunithi yempompo yomlilo,Iyunithi yempompo yomlilo ezinzileyo, Iseti yempompo yomlilo ephathwayo ephakanyiswe ngesandla (3) yahlulwe ngokwe: eziqhelekileyo ngokweempawu ezincedisayo zeseti yempompo.iyunithi yempompo yomlilo,Iyunithi yeMpompo yoMlilo yeSham Tseng,Iyunithi yempompo yomlilo entywilayo
