WebJan 1, 2016 · If it drops low enough to reach the vapor pressure, cavitation will result. When submersible pumps are lowered directly into a wet well, there is no suction-side piping routing water to the pump’s inlet. For pumps applied almost exclusively in wet well applications without suction piping, the potential for cavitation is virtually non-existent. WebAs nouns the difference between aeration and cavitation is that aeration is the process by which air is circulated through or mixed with a substance such as soil or a liquid while cavitation is the formation of pits on a surface.
