1. Silinda: Dangane da matakin matsa lamba na flange, silinda yana da sifofi biyu: simintin gyare-gyare ko ƙirƙira; goyon bayan tsakiya na silinda zai iya inganta kwanciyar hankali na thermal kuma ya yi tsayin daka mafi girma.

2. Core kunshin: The core kunshin (guide vane, impeller taro, shaft, famfo murfin, hali akwatin, da dai sauransu) rungumi dabi'ar wani overall janye zane, wanda damar dubawa da kuma kula da famfo ba tare da motsi da mashigai da kanti bututun.

3. Impeller da vane mai jagora: Tushewa da vane mai jagora suna simintin gyare-gyare. Daidaitaccen impeller da shaft suna zamewa da kafaffen mataki-mataki a cikin rabin zobba. Don yanayin aiki mai nauyi mai nauyi, mai kunnawa shine tsangwama mai dacewa, kuma ana amfani da mataki a kowane mataki na impeller. Tsarin shaft yana sauƙaƙe shigarwa da kiyayewa; DN80 (kanti) da sama bayani dalla-dalla za a iya sanye take da farko-mataki biyu tsotsa impeller don inganta cavitation juriya NPSH.

4. Ma'aunin ƙarfi na axial: An jera masu motsa jiki a jeri kuma suna amfani da ganga mai ma'auni don daidaita ƙarfin axial, sauran ƙarfin axial kuma yana ɗaukar nauyin turawa; da impellers an shirya mayar da baya symmetrically zuwa kai-daidaita da axial karfi, da kuma matsakaici bushing da makogwaro bushing daidaita da saura shaft karfi, da tura qazanta kawai bear ƙananan lodi.

5. Bearings da lubrication: The bearings amfani da man zobe mai kai-lubricating tsarin bearings ko tilasta lubrication tsarin bearings bisa ga shaft ikon da sauri. Dukkanin jerin suna ɗaukar nau'ikan nau'ikan nau'ikan hatimi, kuma ana tallafawa akwatin ɗaukar ƙarfe na carbon a 360 °. Za'a iya kunna Akwatin ɗaukar hoto Cooling ko akwai ruwa mai sanyaya.

6. Shaft hatimi: Tsarin rufewa yana aiwatar da bugu na 4 na API682 "Centrifugal Pump and Rotary Pump Seling System" kuma za'a iya daidaita shi tare da nau'i-nau'i daban-daban na rufewa, zubar da ruwa, da kwantar da hankali.
