Which outcome occurs when a positive displacement pump exceeds its maximum recommended speed in hydraulic oil applications?

💡 Explanation

When a positive displacement pump's speed surpasses its limit, increased shearing of the hydraulic oil results in fluid aeration, because the fluid doesn't have sufficient time to fill the expanding volume. Therefore, increased fluid aeration leading to reduced pressure results, rather than cavitation, motor overload, or rotor seizure which require a different underlying mechanisms.
