Regarding the selection of centrifugal pumps, how is the required head in the pipeline determined?

Hello, friends at HaiChuan. I have a question regarding the selection of a centrifugal pump. Our company has a heat transfer oil electric heating and insulation system, in which a centrifugal pump is used for circulation, with electric heating elements providing heat; the oil flows through four insulated oil tanks connected in series, with each tank having a serpentine flow path for the oil. These four tanks are connected in pairs. Currently, there is almost no pressure indication on the pipeline that returns the oil to the tank. It seems that the centrifugal pump chosen was too small, and we now want to make modifications. How should we select a new centrifugal pump, and how can we determine the required pressure head for the pipelines?
The process requirements specify the pressure and flow rate of the medium in the pipeline; when selecting a suitable model, a margin should be taken into account based on these pressure and flow rate values
