Water-Lifting Devices – Pumps

Abstract

Every day, millions of water pumps deliver water from wells to homes, farms, and businesses. A pump is the link to the water resource. Without pumps, we could not access ground water. As energy costs continue to increase, developing more efficient equipment will contribute to saving energy. Significant opportunities exist to reduce pumping system energy consumption through smart design, retrofitting, and operating practices. Cost of water supply depends on the appropriate selection (type and size for the prevailing condition) and efficiency of the pumping equipments. Each type of pump has its merits and demerits. Proper selection of pumps, motors, and controls to meet the requirement is essential to ensure that a pumping system operates effectively, reliably, and efficiently. The basics of pump control systems and hydraulic system are useful in pump operation. A proper discussion of pumping considers not just the pump, but the entire pumping “system” and how the system components interact. The recommended systems approach to evaluation and analysis includes both the supply and demand sides of the system.
