KRITERIA PEMILIHAN POMPA UNTUK MENGALIRKAN LARUTAN ASAM FOSFAT KE MIXER SETTLER PADA PROSES RECOVERY URANIUM DARI ASAM FOSFAT

PUMP SELECTION CRITERIA for flowing PHOSPHORIC ACID SOLUTION TO MIXER SETTLER in uranium recovery process from phosphoric acid. Mixer-settler plays important roles in uranium recovery process from phosphoric acid. To flow phosphoric acid from feeder tank to mixer settler, constant fluid flow rate is needed. Therefore, this program selects a pump with positive displacement of reciprocating type having specification of plunger single acting 5”x4” triplex, and power 2 HP, to flow phosphoric acid solution with flow rate of 20 kg/s (242 gpm), density of 1300 kg/m3, and viscosity of 4.5 cP, and suction static head of 2 m and discharge static head of 6.4 m. From cavitation evaluation, NPSHavailable of 8.9 m which was greater than NPSHrequired of 4.5 m (specification from pump maker) was obtained.
