Circulating water issues

What pump is used to circulate water in utility systems, and could air be entrained in it?
Reply to 1# lfjt1986: All water is pumped using pumps installed in the circulating water pump room (at a negative elevation); double-suction pumps are commonly used, and there should be no air in them.
It is generally a centrifugal pump and does not contain air
All the pumps in our factory are centrifugal pumps, and they generally do not contain air.
Centrifugal pumps are generally used, and they do not entrain air.
Our factory also uses centrifugal pumps; there is no air in them. It might be due to incomplete exhaust from the heat exchanger, or the water temperature being too high. What phenomena are there?
Centrifugal pumps are generally used; if gas affects the heat exchange efficiency, it is likely due to incomplete exhaust from the heat exchanger
Reply 1# lfjt1986: Centrifugal pumps with double suction are generally used; if the liquid level in the tank is low, air bubbles may form.
