Ho fumana vacuum ho boetse ho tsejoa e le "vacuum pumping", e bolelang tšebeliso ea lipompo tse fapaneng tsa vacuum ho ntša moea ka har'a sets'oants'o, e le hore khatello e ka har'a sebaka e theohele ka tlase ho sepakapaka se le seng. Hajoale, molemong oa ho fumana vacuum le lisebelisoa tse sebelisoang hangata ho kenyelletsa lipompo tsa rotary vane mechanical vacuum, lipompo tsa Roots, lipompo tsa phallo ea oli, lipompo tsa molek'hule tse kopaneng, lipompo tsa adsorption tsa molek'hule, lipompo tsa sublimation tsa titanium, lipompo tsa ion tsa sputtering le lipompo tsa cryogenic joalo-joalo. Lipompong tsena, lipompo tse 'nè tsa pele li arotsoe e le lipompo tsa phetisetso ea khase (lipompo tsa phetisetso ea lipompo), ho bolelang hore limolek'hule tsa khase li ntse li kenngoa ka har'a pompo ea vacuum' me li fetisetsoa tikolohong e ka ntle ho hlokomela phallo; lipompo tse 'nè tsa ho qetela li arotsoe e le lipompo tse tšoarang khase (lipompo tsa ho tšoara vacuum), tse kopantsoeng ka molek'hule kapa li kopantsoe ka lik'hemik'hale leboteng le ka hare la kamore ea ho pompa ho fumana vacuum e hlokahalang. Lipompo tse nkang khase li boetse li bitsoa lipompo tsa vacuum tse se nang oli hobane ha li sebelise oli e le mokhoa oa ho sebetsa. Ho fapana le lipompo tsa phetisetso, tse tlosang khase ka ho sa feleng, lipompo tse ling tsa ho ts'oara li ka khutlisoa, ho lumella khase e bokelletsoeng kapa e khutsitsoeng hore e khutlisetsoe ka har'a sistimi nakong ea ho futhumatsa.
Lipompo tsa "transfer vacuum" li arotsoe ka mekhahlelo e 'meli e meholo: volumetric le momentum transfer. Hangata lipompo tsa phetisetso ea volumetric li kenyelletsa lipompo tsa mochini oa rotary vane, lipompo tsa selikalikoe tsa metsi, lipompo tse fananang le lipompo tsa Roots; lipompo tsa vacuum tse fetisang matla hangata li kenyelletsa lipompo tsa limolek'hule, lipompo tsa jete, lipompo tsa phallo ea oli. Hangata lipompo tsa "capture vacuum" li kenyelletsa lipapatso tsa mocheso o tlase le lipompo tsa sputtering ion.
Ka kakaretso, ts'ebetso ea ho roala e fapane, vacuum ea kamore ea ho roala e lokela ho fihla maemong a sa tšoaneng, 'me ka theknoloji ea vacuum, ho feta ka morao (eo hape e tsejoang e le intrinsic vacuum) ho hlalosa boemo ba eona. Vacuum e ka morao e bolela sebaka sa vacuum ea phaposi ea "vacuum coating" ka pompo ea vacuum ho fihlela litlhoko tsa ts'ebetso ea "vacuum" ea "vacuum" e phahameng ka ho fetisisa, le boholo ba vacuum ena, haholo-holo e itšetlehileng ka matla a ho pompa.
