A circulation pump, also known as a recirculation pump or a circulating pump, is a type of pump used to circulate fluid within a closed system. It is commonly used in heating systems, hot water recirculation systems, and other applications where continuous circulation of fluid is required.
The main function of a circulation pump is to move fluid, typically water or a water-glycol mixture, through a closed loop system. This helps to distribute heat evenly throughout the system, maintain a consistent temperature, and prevent stagnation or cold spots.
Circulation pumps are typically centrifugal pumps, utilizing an impeller to create the necessary pressure to circulate the fluid. They are designed to operate continuously, providing a steady flow of fluid through the system.
In heating systems, a circulation pump is often used to circulate hot water from the boiler or heat source to the radiators or underfloor heating system. This ensures that heat is evenly distributed throughout the space and maintains a comfortable temperature.
In hot water recirculation systems, a circulation pump is used to continuously circulate hot water from the water heater to the faucets or fixtures, reducing the wait time for hot water and preventing wastage of water.
Circulation pumps are available in different sizes and power capacities to suit various system requirements. They are typically designed for quiet operation and energy efficiency.
Proper installation and maintenance of a circulation pump are important to ensure optimal performance and longevity. This includes regular inspection, cleaning or replacement of the pump strainer or filter, and checking for any leaks or damage.
Overall, a circulation pump plays a crucial role in maintaining the flow and temperature of fluid within a closed system, ensuring efficient operation and comfort.
