1. Ukulethwa koketshezi: Inhloso esemqoka yamaphampu wezimboni ukuletha uketshezi oluhlukahlukene, kufaka phakathi uketshezi, amagesi, njll.
2. Ukucindezelwa: Kwezinye izimo lapho kudingeka khona ingcindezi ephezulu, amaphampu wezimboni angadlala indima ekucindezelweni ukuze aqinisekise ukuthi uketshezi lungathuthwa kahle.
I-3. Ukucindezela: Amanye amaphampu wezimboni, njengamaphampu we-compressor, angasetshenziswa ukucindezela amagesi.
I-4. Ukucishwa: Amanye amaphampu wezimboni anomsebenzi wokuvalwa kwezimboni, okusetshenziselwa ukudala indawo ye-vacuum ekukhiqizweni kwezimboni.
