Why Your Water Pump Overheats? Root Causes and Effective Solutions

This science-based guide teaches how to properly select a water pump by accurately calculating and balancing head (total resistance including static lift, friction losses, and suction) and flow rate (volume delivered per unit time)—two inversely related parameters shown on the pump's performance curve. It explains common mistakes (guesswork, ignoring dynamic head, focusing on only one parameter, or overlooking application needs), provides practical calculation steps, mitigation strategies, and emphasizes matching the operating point to the best efficiency zone to prevent inefficiency, cavitation, energy waste, and early pump failure across industrial, agricultural, commercial, and residential uses.
