Ompompi bayizinto ezibalulekile zenhlanzeko kokubili amakhaya namabhizinisi. Izinto ezizikhethayo zithinta ngqo ukuqina kwazo, ukuphepha, nolwazi lwabasebenzisi. Emhlabeni jikelele, abathengi baya ngokuya befuna ikhwalithi yompompi, okwenza kubaluleke kakhulu ukuthi izinkampani ezithumela ngaphandle ziqonde izici zezinto ezihlukene kanye nezimo ezisebenzayo.
Njengamanje, izinto ezisetshenziswa kakhulu zompompi ezimakethe zifaka insimbi engagqwali, ingxubevange yethusi, ingxubevange ye-zinc, nepulasitiki. Ompompi bensimbi engagqwali bayinketho edumile emakethe-yokugcina ephezulu ngenxa yokumelana nokugqwala kwabo okuhle kakhulu kanye nokuvumelana nendawo ezungezile{2}} insimbi engagqwali inikeza izici ezinhle kakhulu zokulwa namagciwane futhi ayinazo izinto eziyingozi njengomthofu, ehlangabezana nezindinganiso zomhlaba wonke zezemvelo futhi ifanele ukusetshenziswa ezindaweni ezinezidingo zekhwalithi ephezulu yamanzi. Kodwa-ke, insimbi engagqwali kunzima ukuyicubungula futhi ibiza kakhulu, okwenza ukuthi isetshenziswe ikakhulukazi{4}emigqeni yomkhiqizo wokugcina.
Ompompi bengxube ye-Copper bayinketho ethandwayo emakethe yomhlaba, ikakhulukazi ama-alloys ethusi anobungani bemvelo anokuqukethwe komthofu okungaphansi kuka-0.25%. I-Copper inezinto zemvelo zokulwa namagciwane, futhi inqubo yayo yokuphonsa eyinkimbinkimbi ivumela imiklamo eyinkimbinkimbi. Kodwa-ke, ukumelana ne-oxidation kompompi bengxubevange yethusi kuncike ekunambithekeni okungaphezulu, okufana ne-chrome noma i-nickel plating, futhi ikhwalithi yalezi zimbobo zithinta ngqo impilo yomkhiqizo. Kwezohwebo zamazwe ngamazwe, i-EU's RoHS Directive kanye nezinga le-US NSF linemithetho eqinile mayelana nokuqukethwe okuholayo nokuphepha kokumbozwa kompompi bengxube yethusi. Abathumeli bangaphandle kumele baqinisekise ukuthi imikhiqizo yabo ihambisana nezidingo zokulawulwa kwezimakethe zabo eziqondiswe kubo.
Ingxubevange ye-zinc kanye nompompi bepulasitiki basetshenziswa kakhulukazi phakathi- nezimakethe eziphansi-. Ingxubevange ye-Zinc inikezela ngezindleko eziphansi kodwa isengozini yokungenwa yi-oxidation, edinga ukwelashwa okuhle kwendawo. Ompompi bepulasitiki abasindi futhi ababizi, kodwa banikeza ukuqina okuncane futhi ngokuvamile bafanele ukufakwa{4}}kwezindleko eziphansi.
Lapho kukhethwa okokusebenza kompompi, izinkampani kufanele zicabangele kabanzi imikhuba yabathengi bemakethe eqondiwe, izidingo zokulawula, nezici zezindleko. -Izinto zompompi zekhwalithi ephezulu azigcini nje ngokuthuthukisa ukuncintisana komkhiqizo kodwa futhi ziqinisa ukwethembeka komkhiqizo emakethe yamazwe ngamazwe.
