Hello! Do ALL the pumps create suction cavitation (ie bubbles of vacuum inside the water)? Or it is a rare phenomenon? And does it increase with pump speed? thanks!

Essentially all pumps that are applied improperly with respect to suction pressure, yes. Properly applied pumps do not cavitate.
 
Yes, cavitation phenomenon increases with pump speed
