Mechanical pumps are devices used to move fluids by converting mechanical energy into hydraulic energy. They operate through various mechanisms, such as rotary or reciprocating motion, to create pressure differences that facilitate fluid movement. Common types include centrifugal pumps and positive displacement pumps, each suited for different applications. These pumps are widely used in industries like water treatment, oil and gas, and chemical processing. They can handle various fluids, including water, oil, and slurries, making them essential for tasks such as irrigation, heating, and cooling systems. Their efficiency and reliability make them a vital component in many systems.
