Isixhumi esisheshayo sochungechunge lwe-SP yisixhumi sepayipi somoya esenziwe nge-zinc alloy. Lolu hlobo lwesixhumi lunamandla amakhulu nokumelana nokugqwala, okulwenza lufanelekele izinhlelo zokudlulisa umoya negesi.
Izici zochungechunge lwe-SP izixhumi ezisheshayo ukufakwa okulula, ukuqaqa okulula, nokusebenza okuthembekile kokubeka uphawu. Ngokuvamile zisetshenziswa ezinhlelweni zomoya, njengezinhlelo zomoya ezicindezelweyo, amasistimu we-hydraulic, namasistimu we-vacuum.
Impahla yalesi sixhumi esisheshayo, i-zinc alloy, inokumelana okuhle kokugqoka nokumelana nokugqwala, futhi ingasetshenziswa ezindaweni ezinokhahlo isikhathi eside. Ngokuvamile basebenzisa izixhumanisi ezinentambo noma ezifakiwe ukuze kuqinisekiswe ukuqina nokuvala uxhumano.
Izixhumi ezisheshayo zochungechunge lwe-SP zisetshenziswa kakhulu kuma-compressor emoyeni, ithuluzi le-Pneumatic kanye nemishini yomoya. Angakwazi ukuxhuma ngokushesha futhi anqamule amapayipi, athuthukise ukusebenza kahle komsebenzi futhi enze kube lula ukulungiswa.
