Will the heat transfer oil circulate and the diameter of the pump outlet to the inlet be changed? Will this cause the pump to hold pressure?

There is a circulation pipeline for thermal oil circulation. The pump outlet pipeline is finally changed from DN200 to DN50 (equipment heating coil), and then changes from 50 to 200 when it comes back. Will this cause the pump to hold pressure?

How much flow a pump with a 200 outlet pipe diameter can achieve depends on the BEP point and the resistance curve of the pipeline system.

Not reliable, there may be other sub-plots

Is it stressful to calculate it through software? It feels unreliable intuitively. The design institute has to complete the calculation and let the results speak for themselves.
