Amaphampu ngezikulufu ezintathuayikilasi elikhulu kunawo wonke lamaphampu ngezikulufu eziningi asebenzayo namuhla. Zibuye zisetshenziswe ezinqubweni zokucwenga zemikhiqizo ye-viscous ephezulu yokushisa efana ne-asphalt, i-vacuum tower bottoms kanye namafutha kaphethiloli ayinsalela.
Amaphampu angama-screw amathathu avame ukusetshenziselwa:
ukuthambisa imishini
amakheshi we-hydraulic
ukuthutha uwoyela kaphethiloli kanye nenkonzo yokushisa
amandla emishini ye-hydraulic

I-Three-Screw Pump iyiphampu enhle yokususa, futhi inezinzuzo eziphawulekayo ezifana nalezi:
isakhiwo esilula, ivolumu encane, ukuvunyelwa ukuphenduka ngesivinini esikhulu, ukuzinza kanye nokusebenza kahle okuphezulu, njll. Ngokusebenzisa isimiso sokuhlanganisa isikulufu nokuncika ekuxhumaneni okuhlangene kwezikulufu ezizungezayo kubhulokhi yepompo, iphampu enezikulufu ezintathu incela okuphakathi nendawo. futhi iyivale ku-meshing cavity, bese iyiphushela embotsheni yokukhipha i-axial ye-axial yezikulufi ngesivinini esifanayo, bese yenza ingcindezi ezinzile embotsheni yokukhipha amanzi.

Uchungechunge lwe-3QGB lokulondoloza ukushisa okuphezulu-viscosityitiyela elinezikulufu ezintathuithuthukiswe Sinoroader ngemva kweminyaka eminingi yocwaningo nokwandisa ukubambisana phakathi isikulufa futhi futha block, futhi phakathi isikulufa ukushayela nesikulufi eliqhutshwa esekelwe ezintathu-isikulufa futha, ukuze uqaphele ukulethwa og izinga lokushisa eliphezulu kanye high-viscosity abezindaba. Amaphampu e-Sinoroader bitumen anezikulufu ezintathu  kakhulu asetshenziselwa isitshalo sokuxuba itiyela. Ingaklanywa ngokwesimo sekhasimende, iphampu yegiya yensimbi engagqwali, Inokukhethwa okuphelele kwamaphampu ashelelayo. Iphampu ye-viscosity insulation ephezulu, Iphampu eyinsalela ihlangene, impilo ende, Ukubukeka okuhle.
