Which risk increases when viscous positive displacement pump operates at excessively high speed with a low viscosity fluid?

💡 Explanation

When a positive displacement pump is operated at high speeds with a low viscosity fluid, increased internal slippage occurs because fluid passes through clearances before the displacement cycle completes, reducing outflow. Therefore increased slippage results instead of rotor seizure, stator failure, or cavitation, requiring opposing states and different physical locations.
