A makwaara inweta vacuum dị ka "vacuum pumping", nke na-ezo aka na ojiji nke pump vacuum dị iche iche iji wepụ ikuku dị n'ime akpa ahụ, ka nrụgide dị n'ime oghere ahụ wee daa n'okpuru otu ikuku. Ugbu a, iji nweta vacuum na ngwaọrụ ndị a na-ejikarị eme ihe gụnyere rotary vane mechanical vacuum pumps, Roots pumps, oil diffusion pumps, composite molecular pumps, molecular sieve adsorption pumps, titanium sublimation pumps, sputtering ion pumps na cryogenic pumps na ndị ọzọ. N'ime pumps ndị a, a na-ahazi pumps anọ mbụ dị ka gas transfer pumps (transfer vacuum pumps), nke pụtara na a na-amịnye molecules gas mgbe niile n'ime vacuum pumps ma na-agbapụ ha na mpụga iji mezuo mwepụta; a na-ahazi pumps anọ ikpeazụ dị ka gas capture pumps (capture vacuum pumps), nke a na-ejikọta molecule ma ọ bụ kemịkalụ na mgbidi dị n'ime nke ụlọ pumping iji nweta vacuum achọrọ. A na-akpọkwa pumps capture-capture pumps vacuum-free oil n'ihi na ha anaghị eji mmanụ eme ihe dị ka ihe na-arụ ọrụ. N'adịghị ka mgbapụta mbufe, nke na-ewepụ gas ahụ kpamkpam, ụfọdụ mgbapụta njide nwere ike ịgbanwe agbanwe, na-enye ohere ka a na-ewepụta gas a nakọtara ma ọ bụ nke a kpọchiri akpọchi laghachi na sistemụ ahụ n'oge usoro ikpo ọkụ.
E kewara pọmpụ vacuum mbufe ụzọ abụọ: volumetric na momentum mbufe. pọmpụ mbufe volumetric na-agụnyekarị pọmpụ mechanical rotary vane, pọmpụ mgbanaka mmiri mmiri, pọmpụ na-agbanwe agbanwe na pọmpụ Roots; pọmpụ vacuum mbufe na-agụnyekarị pọmpụ molekul, pọmpụ jet, pọmpụ mgbasa mmanụ. pọmpụ vacuum Capture na-agụnyekarị pọmpụ adsorption dị ala na pọmpụ ion sputtering.
