ZA(O) ndi yopingasa, kugawanika kwa radial, siteji imodzi, kuyamwa kumodzi, kupopera kwapakati pa centrifugal ndi casing volute.Centerline wokwera;Pump casing, chivundikiro ndi impeller amaperekedwa ndi mphete zosindikizira, zomwe zimakhazikika ndi zomangira zosokoneza. Hole yoyezera ndi mphete yosindikizira imayikidwa kuti igwirizane ndi mphamvu ya axial, kuonetsetsa moyo wautumiki wa kubereka.Ma radial bearings ndi ma cylindrical roller bearings, ndipo ma thrust bearings ndi aang'ono olumikizana ndi mpira, omwe amatha kunyamula mphamvu za axial kuchokera mbali ziwiri.
