Ko te Pūkaha Pūkaha Momo Pēhanga Kaplan he mea hanga mai i te pūkaha Kaplan me te pūkaha mā te whakamahi i te hononga. Ko te pūkaha waipēhi he mea hanga mai i te vane ārahi, te impeller, te pou matua, te hiri me te whakatārewatanga me ētahi atu. I te mea ka arahina te wai pēhanga teitei mā roto i te paipa tomo ki te pūkaha, ka akiaki te wai impeller kia huri. Ka puta te hiko ina huri te rotor ki te stator.

Ko te tāpine Kaplan momo pēhanga he mea whakairi poutū. Ko ōna painga e whai ake nei:

1. He ngāwari te tāuta i te tomokanga paipa;

2. Kua wehea te tāpine me te whakaputa hiko, he ngāwari ki te tiaki;

3. E toru ngā whāriki o te tāpine; e toru ngā whāriki o te whakaputa hiko, he pono ake tēnei;

4. Mā te pūnaha whakahinuhinu hinu motuhake o te tāpine ka roa ake te ora o ngā peera.
