Dear seniors, what type of pump should be used to transport critical evaporating liquids in order to eliminate cavitation?

Cavitation generally occurs in pumps when the process parameters are at critical levels (i.e., when the net positive suction head available is too low). It cannot be eliminated; only avoided. It is necessary to verify the net positive suction head available for the device, as well as how much head margin can be reserved for the pump. If no suitable centrifugal pump can be found within this range, then a pump that uses gas-liquid mixing for transport, such as a positive displacement pump, should be used. If this issue still cannot be resolved, then the only option is to adjust the process parameters (increase pressure/lowers temperature) in order to increase the net positive suction head of the device.
I’m not sure if submersible pumps or bag pumps would work
What medium, what temperature? Complete parameters are required to select the appropriate option
