Dual-process technology

Has anyone implemented a process in which there is an evaporator at each of the inlet and outlet of the forced circulation pump? What issues need to be taken into consideration? What should be the appropriate distance between the outlet of the forced circulation evaporator and the inlet of the pump? I would appreciate some guidance from the experts here.
Won’t this cause cavitation in the circulation pump?
The liquid level in the crystallizer is high enough; the pump manufacturer says cavitation will not occur, but it’s uncertain what the actual situation is

If exporting one evaporator is sufficient to meet the requirements, why install two? Moreover, it is at the pump inlet where the temperature of the evaporated saturated liquid is high; to overcome cavitation, it is necessary to raise the liquid level in the evaporator, which in turn requires increasing the height of the equipment located before the inlet evaporator. Otherwise, an additional transfer pump will be needed, resulting in more equipment and higher energy consumption. What advantage is there in doing this? I don’t quite understand this way of thinking.
