Amaphampu alungele izinhlelo zokusebenza ezihlukahlukene futhi aklanyelwe ukumelana nokucindezela okukhulu, ukusetshenziswa kwamandla aphansi nokusebenza okuthulile kwe-bushang kunikeza ikhwalithi ephezulu yokucaciswa kwemikhiqizo eyenziwe ngokwezifiso kanye nemiklamo ku-NBR, HNBR, VITON kanye ne-PTFE yezinhlobonhlobo zamaphampu. Ngokuya ngosayizi wefomu, izinga lokushisa lokusebenza, imvelo yesicelo, i-sealing medium, ingcindezi yokuvala, isivinini sokusebenza kanye nenqubo yokufaka, i-bushang inikeza izixazululo ze-pump seal ezihlanganisa izimpawu zamafutha, izindandatho ezihlukahlukene, ama-gaskets nezinye izingxenye zerabha ze-elastomer.
