Self-priming pump is self-priming centrifugal pump, ine zvakanakira compact chimiro, kushanda kwakaringana, kushanda kwakadzikama, kugadzirisa kuri nyore, kushanda kwepamusoro, hupenyu hurefu, uye kusimba kwakasimba kwekuzvimiririra.Iko hakuna chikonzero chekuisa vheji yepasi mupombi, uye inongoda kuve nechokwadi chekuti pane huwandu hwejekiseni remvura mumuviri wepombi usati washanda.Zvinwiwa zvakasiyana zvinogona kushandisa zvinhu zvakasiyana zvepombi yekuzvimisira.
Kana iyo yekusveta nhanho yemvura iri pazasi pe impeller, inofanirwa kunge isati yazadzwa nemvura kana ichitanga, izvo zvakanyanya kunetsa.Kuti uchengetedze mvura mupombi, valve yepasi inoda kuiswa panzvimbo inopinza yepombi yekudhonza.Apo pombi iri kushanda, valve yepasi inokonzera kurasikirwa kukuru kwe hydraulic.Iyo inonzi self-priming pump haidi kudiridzwa isati yatanga (yekutanga kutanga mushure mekuisa ichiri kuda kudiridzwa).Mushure menguva pfupi yekushanda, pombi pachayo inogona kusveta mvura uye kuiisa mubasa remazuva ose.
