Cavitation or Aeration? You Can Hear the Difference!

WebAug 4, 2015 · Cavitation is the formation and collapse of air cavities in liquid. When hydraulic fluid is pumped from a reservoir, pressure drops in the suction line to the pump. Despite what many people believe, the fluid is not sucked into the pump. Rather, it is pushed into the pump by atmospheric pressure (as shown in the left-hand illustration). WebPneumatic spray foam systems employ the simplest two-component pumping technology: A single air motor driving two pumps. The air motor and pumps are sized appropriately …
