Pump design involves creating devices that move fluids by converting mechanical energy into hydraulic energy. Key components include the impeller, which increases fluid velocity, and the volute, which helps convert that velocity into pressure. The design must consider factors like flow rate, pressure requirements, and the type of fluid being pumped. Different types of pumps, such as centrifugal pumps and positive displacement pumps, serve various applications. Centrifugal pumps are commonly used for large volumes of liquids, while positive displacement pumps are ideal for precise flow control. Effective pump design ensures efficiency, reliability, and longevity in various industrial and domestic settings.
