Positive displacement pumps is not given high flowrate so It cannot use.

Because process is high flow rate required. So, we can use centrifugal pumps.

Centrifugal pump is correct answer.

It is a above ground drive for a submersible pump in a borehole. Used to raise crude oil from oil wells. Crude Oil generally has high viscosity, surface transfer pumps (centrifugal, plunger pumps, hydraulic pumps) they are always required to be geared or hydraulic to ensure positive displacement.

For high flow rate centrifugal pump is the right answer.

Centrifugal pump is right answer because It's have high flow rate compared with positive displacement pump. For decrease the viscosity preheater are installed in pipe line.
