Kunezici eziningi okufanele zicatshangelwe lapho ukhetha i- iphampu yecala lokuhlukaniswa kwe-axial kanye ne-impeller ngendlela efanele. 

Okokuqala, sidinga ukwazi ukuthi uketshezi ludinga ukuthuthwa kuphi nokuthi yiliphi izinga lokugeleza. Inhlanganisela yekhanda nokugeleza okudingekayo kubizwa ngokuthi iphoyinti lomsebenzi. Iphuzu lomsebenzi lihlobene ngokuqondile nejometri ye-impeller edingekayo. Izinhlelo zokusebenza ezinokumpompa okude okuqondile (ikhanda eliphezulu) zidinga ama-impeller amakhulu amakhulu angaphandle kunezinhlelo zokusebenza ezinokumpompa okufushane okuqondile (ukupompa).

Okunye ukucatshangelwa okuhlobene ngokuqondile nosayizi we-impeller okuqukethwe okuqinile okulindelekile kuhlelo lokusebenza. Izinhlelo zokusebenza eziningi zinezinhlobonhlobo zezinto eziqinile kumidiya ephonsiwe. Lezi zinto eziqinile zingasukela emfucumfucwini emincane ehubhukayo njengesihlabathi noma ukushefa kwensimbi kuye ezintweni ezicolekile ze-fibrous kuya kokuqinile okukhulu okungangosayizi we-baseball noma ngaphezulu. Iphampu kanye ne-impeller ekhethiwe kufanele ikwazi ukudlula lezi zinto eziqinile ngenkathi igwema ukuvala nokulimala ekugqokeni. Ukucatshangelwa okwengeziwe kufanele futhi kunikezwe okokusebenza ezansi nomfula we-axial split case futha. Nakuba iphampu ingakhethwa ukuze idlulise uhlobo oluthile lwezinto eziqinile, akunakucatshangwa ukuthi amapayipi aphansi komfula, amavalvu, nezinye izinto zokusebenza zenqubo zizoba namandla afanayo okubamba okuqinile. Ukwazi okuqukethwe okuqinile okulindelekile oketshezini kubalulekile hhayi kuphela ekukhetheni iphampu kasayizi olungile kanye nesixhumi, kodwa nasekukhetheni isitayela se-impeller esifanela uhlelo lokusebenza.

Enye yezinto eziqinile ezibamba ama-impeller yi-impeller evulekile. Lesi siphehli sivame ukusetshenziswa ekuhlanzeni indle namanzi angcolile futhi sinejiyomethri ehlanganisa amaphaseji phakathi kwama-blades nohlangothi oluvulekile olubheke endaweni yokungena. Izikhala phakathi kwama-blades zinikeza indlela ebushelelezi yokuthi i-impeller isunduze izinto eziqinile ezingenayo zisuka embotsheni yokudonsa i-impeller ziye ku-volute futhi ekugcineni ngokukhishwa kwepompo.

Enye inketho yokuphatha okuqinile yi-vortex noma i-impeller ephelile. Lolu hlobo lwe-impeller lufakwe ngaphakathi kwe-casing (ukudala indawo enkulu evulekile phakathi kwe-impeller kanye ne-suction port) futhi idonsa ukunyakaza koketshezi ngama-vortices adalwe ukujikeleza okusheshayo kwe-impeller. Yize le ndlela ingasebenzi kahle, ihlinzeka ngezinzuzo eziningi zokudlula okuqinile. Izinzuzo eziyinhloko yisikhala esikhulu samahhala kanye nokuvinjwa okuncane kokudlula okuqinile.

Amaphampu asetshenziswa ezindaweni eziphakeme anesethi yawo yokucatshangelwa okuqinile okubamba. Njengoba lezi zinhlelo zokusebenza ngokuvamile zisebenzisa amapayipi amancane, usayizi wokudlula okuqinile wesistimu yonke kufanele ucatshangelwe, hhayi nje iphampu. Ngokuvamile, abakhiqizi bephampu ye-axial split case abahlinzeka ngamaphampu anomfutho ophezulu bazofaka isihlungi endaweni yokungena ukuze kuvinjelwe izinto eziqinile ezinkulu ukuthi zingangeni empompini. 

Lokhu kulungele izinhlelo zokusebenza ezinengcindezi ephezulu lapho kulindeleke khona okuqinile okuncane, kodwa kungabangela ukuvala uma okuqinile okwanele kunqwabelana endaweni yesikrini.

Kunezici eziningi okufanele zicatshangelwe lapho ukhetha i-axial split case futha kanye ne-impeller, futhi ukuqonda izitayela ezihlukahlukene zamaphampu nama-impellers ngokuvamile kuyisinyathelo esibucayi kakhulu.
