Do Positive Displacement Pumps Cavitate?

Cavitation is a potentially damaging effect that occurs when the pressure of a liquid drops below its saturated vapour pressure. ... Cavitation can also occur in positive displacement pumps such as gear pumps and plunger pumps.

What causes pump to Cavitate?

Cavitation happens when bubbles, or voids, form within a fluid because the pressure quickly drops below the vapor pressure. When the bubbles experience higher pressures they collapse, creating small shockwaves that, over time, damage parts.
