Which outcome is caused when a positive displacement pump exceeds the system's maximum allowable working pressure (MAWP)?

💡 Explanation

When pressure exceeds MAWP, the internal relief valve opens because it is designed to protect the pump and system, diverting flow and preventing further pressure increase. Therefore fluid bypass via internal relief results, rather than rotor seizure, cavitation, or demagnetization which stem from distinct mechanisms and conditions.
