Khetho ea mantlha ea lisebelisoa bakeng sa lipompo tsa mekhahlelo e mengata e ipapisitse le tikoloho ea ts'ebetso ea pompo le thepa ea mokelikeli o pompuoang. Ka tlase ke likhetho tse tloaelehileng tsa pompo ea multistage, hammoho le litšoaneleho tsa tsona le maemo a sebetsang:
1. Tšepe e Hloekileng:
Boitsebiso:Lisebelisoa tse sa hloekang tsa Austenitic tse kang 304 (0Cr18Ni9) le 316 (0Cr18Ni12Mo2Ti) li sebelisoa hangata.
Likaroloana:Ho hanyetsa kutu e ntle haholo, e loketseng ho pompa maro a nang le mecha ea litaba e senyang hanyenyane.
Lisebelisoa:E sebelisoa haholo phepelong ea metsi, ho matlafatsa indasteri, lipalangoang tsa metsi a indasteri, tlhoekiso ea metsi, le likarolo tse ling.
2. Tšepe:
Boitsebiso:Grey cast iron (HT) le ductile iron (QT) ke mefuta e 'meli e tloaelehileng.
Likaroloana:Cast iron e fana ka thepa e ntle ea ho lahla le ho hanyetsa, empa e na le khanyetso e mpe ea kutu.
Lisebelisoa:Hangata e sebelisetsoa ho pompa metsi a hloekileng kapa mecha ea litaba e senyang hanyenyane.
3. Ts'epi
Boitsebiso:Ha khatello e feta 1.6 MPa,{1}}likarolo tse jereng khatello hangata li entsoe ka tšepe e entsoeng ka tšepe, joalo ka ZG230-450.
Likaroloana:Cast steel e fana ka matla a holimo, 'me e sebetsa ka thata, e etsa hore e tšoanelehe bakeng sa-khatello le ho se sebetse{1}}mesebetsi e manganga.
Kopo:Hangata e sebelisoa litsamaisong tsa indasteri tse tlamehang ho mamella khatello e phahameng.
4. Sebopeho sa Carbon Structural Steel:
Boitsebiso:Carbon structural steel e tlwaelehileng (jwalo ka Q235) le{1}} carbon structural steel ya boleng bo hodimo (jwalo ka 45 steel).
