Ngokubhekiselele ekubeni kukho umthombo wamandla, zahlulwe zibe: iimpompo zomlilo ezingenawo umthombo wamandla (ezibizwa ngokuba ziimpompo),iyunithi yempompo yomlilo(ekubhekiswa kuyo njengeyunithi yokumpompa).

1. 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, lihlukaniswe: ipompo yomlilo ephantsi, i-medium-pressure fire pump, i-medium-low-low pressure pump, i-high-pressing fire pump, kunye ne-high-low fire pump.

3. Yahlulwe ngokusetyenziswa: impompo yomlilo yokubonelela ngamanzi,Impompo yomlilo ezinzileyo, unikezelo lwempompo yolwelo lolwelo lwamagwebu.

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

Mbini,iyunithi yempompo yomliloIngahlelwa ngokwale migaqo ilandelayo:

1. Ngokohlobo lomthombo wamandla, lwahlulwe lwaba:Iyunithi yempompo yomlilo ye-injini ye-diesel, Iseti yempompo yomlilo yemoto yombane, i-gas turbine fire pump set, i-petroli ye-injini yokucima umlilo.

2. Ukwahlulwe ngokusetyenziswa: isethi yempompo yomlilo yonikezelo lwamanzi,Iyunithi yempompo yomlilo ezinzileyo, Iseti yempompo yomlilo ephathwayo ebanjwe ngesandla (3) yahlulwe ibe: isethi yempompo yomlilo eqhelekileyo, iseti yempompo yomlilo enzulu, kunye nempompo yomlilo ephantsi kwamanzi iseti ngokweempawu ezincedisayo zeseti yempompo.
