Introduction to Circulating Pumps
Circulating pumps are essential devices widely used in various industries and domestic applications. Their primary function is to circulate fluids, typically water, within a closed - loop system. In heating systems, they ensure the continuous flow of hot water from the boiler to radiators or under - floor heating pipes, maintaining a consistent temperature. In industrial processes, circulating pumps are used for cooling, chemical processing, and transporting fluids between different parts of a production line. They are designed to operate efficiently, with low energy consumption and minimal maintenance requirements.
