Ngā wāhanga e manawapa ana mō te papu paru, ngā raina uku, ngā piston, ngā takirere momi me te tukunga mō ngā papu paru HDD, e tika ana mō ngā taputapu FMC/APLEX/KERR/DX

He taputapu hurihuri tino nui te papu paru mō ngā mahi keri hinu me te hau, i hangaia hei huri i te paru keri puta noa i te poka.
Ko tāna mahi matua he kawe i te paru keri pēhanga teitei mai i te mata ki te mata keri, kātahi ka hurihia kia hoki mai hei kawe i ngā tapahi ki te mata. E whā ngā painga matua o tēnei rere tonu:
• Whakamatao me te Whakahinuhinu: Ka whakaiti i te waku me te wera hei tiaki i te mata wiri me te aho mai i te pakaru nui.
• Te Horoi i te Pū: Ka pupuri i te ara poka mārama hei whakapai ake i te whai huatanga o te keri.
• Te Whakapūmau i te Hanganga: Ka waihanga i te pēhanga wai hei ārai i te rerenga mai o te wai hanganga me te hinganga o te poka.
• Mana Pēhanga: Ka whakataurite i te pēhanga hanganga kia kore ai e whana, e pupuhi rānei, kia haumaru ai ngā mahi.
Mā ngā miihini, ngā motuka hiko rānei e ārahi, ka whakauruhia e ā mātou papu paru ngā wāhanga tino tika (ngā piston, ngā takirere, ngā pito wai, me ētahi atu) hei tuku i te pēhanga pono me te rere tonu o te paru. He mea nui ēnei mō te keri haumaru, whai hua hoki i roto i te umanga hinu me te hau.
