Reducing pressure at the inlet to a centrifugal pump creates cavitation. No air is introduced to the process fluid(water) yet bubbles form as gas vapor bubbles escape, and pump efficiency is reduced.
When the pressure at the suction is low enough that the water reaches its boiling point (as we know, lower pressure means lower boiling point). When this happens, steam bubbles will form. This in itself is not a problem, the problem arises when the water passes the suction side and goes into the discharge side where the pressure is higher again, this means those steam bubbles will collapse, literally exploding. This is cavitation.

Awesome Demo!
can we see this in slowmotion?
Where did you get the cover of the pump
Vlogger 😂😂😂
Cavitation means what
I think it's when water boils and air bubbles form
When pressure at suction is lesser than atmosphere pressure water boils and start forming bubbles😊
When low pressure bubbles form, then collapse at supersonic speeds that make crators and slowly break down the prop/propeller/impeller in question.
it means it hurts the pump impellers :*(
