Iphampu ye-self-priming iyiphampu ye-centrifugal ene-self-priming centrifugal, enezinzuzo zesakhiwo esihlangene, ukusebenza okulula, ukusebenza okuzinzile, ukugcinwa okulula, ukusebenza kahle okuphezulu, impilo ende, namandla okuzibamba aqinile.Asikho isidingo sokufaka i-valve engezansi epayipini, futhi kudingeka kuphela ukuqinisekisa ukuthi kunomthamo omningi womjovo woketshezi emzimbeni wepompo ngaphambi kokusebenza.Uketshezi oluhlukene lungasebenzisa izinto ezihlukene zephampu yokuzilungisa.
Uma izinga loketshezi lokumunca lingaphansi kwe-impeller, kufanele ligcwaliswe ngaphambili ngamanzi lapho liqala, okuyinto engalungile kakhulu.Ukuze ugcine amanzi empompini, ivalvu engezansi idinga ukufakwa endaweni yokungena yepayipi lokumunca.Lapho iphampu isebenza, i-valve engezansi ibangela ukulahlekelwa okukhulu kwe-hydraulic.Iphampu ebizwa ngokuthi i-self-priming pump ayidingi ukuniselwa ngaphambi kokuqala (ukuqala kokuqala ngemva kokufakwa kusadinga ukuniselwa).Ngemva kwesikhathi esifushane sokusebenza, iphampu ngokwayo ingamunca amanzi futhi iwabeke emsebenzini ovamile.
