1. I-I-1B yochungechunge lwepompo yesikulufu iyiphampu yokuthutha enesikulufu esisodwa esebenzisa isenzo somfutho esikhiqizwa ukuzungezisa kwe-spiral groove ukuthutha uketshezi noma udaka.Isebenza esenzweni esikhethekile se-slurry medium, ikakhulukazi esetshenziswa kabanzi ezindaweni ezinjengezimboni zamakhemikhali, indawo yokuphisa utshwala, isigayo samaphepha, i-cannery, ilabhorethri kanye ne-winery,
2.l-1B isikulufu futha ihlanganisa (a), (b) kanye (F) izinhlobo..
(1) .l-1B (a) isetshenziswa odongeni olujwayelekile lokudla okunedaka kanye nokungathathi hlangothi kokudla, Izingxenye zakhona zangaphakathi zenziwe ngensimbi evamile ye-carbon steel futhi umkhono wenjoloba wepompo wenziwe ngerabha yokudla evamile.
(2).I-1lB (b) iyasebenza ku-asidi egxilile.kanye noketshezi lwe-alkali, olumelana nokugqwala kwe-asidi noketshezi lwe-alkali.Izingxenye zalo zangaphakathi zenziwe ngensimbi engagqwali futhi umkhono wenjoloba wepompo umelana ne-asidi ne-alkali.
(3).I-I-1B (F) iyasebenza ku-asidi egxilile noketshezi lwe-alkali olunamandla amakhulu nokumelana okuqinile.Izingxenye zayo zangaphakathi kanye ne-casing yonke yenziwe ngensimbi engagqwali.
