Kumzi mveliso we-petrochemical, ukukhetha impompo efanelekileyo emininzi kubalulekile. Xa kuthelekiswa nokucoca iimpompo zamanzi, ukukhetha impompo yeekhemikhali kufuna ingqalelo ekhethekileyo kwizinto ezinje ngeempawu zemithombo yeendaba, ukuxhathisa ukubola, kunye nokuqwalaselwa kokhuseleko. Kweli nqaku, uChangsha Zhonglian Pump Industry, umvelisi ophambili weempompo ezininzi, ziya kubonelela ngengxelo eneenkcukacha yomahluko ophambili kunye nokuqwalaselwa okubalulekileyo xa kukhetha iimpompo ezininzi ezisetyenziswa kwicandelo le-petrochemical. xa kuthelekiswa nezo ziyilelwe ngokukodwa ukuhambisa ukubonelela kwamanzi okucacileyo ukuqonda okuxabisekileyo kwesalathiso sakho.
