Understanding Small Recirculating Pumps
What is a Small Recirculating Pump?
A small recirculating pump is designed to continuously circulate water or other fluids within a closed system. This continuous flow helps maintain consistent temperatures, prevents stagnation, and enhances efficiency in various systems.
How Do Small Recirculating Pumps Work?
These pumps operate by drawing fluid from one point in a system and pushing it through pipes back to the source. The mechanism typically involves an impeller that creates flow, and depending on the type of pump, this process can happen in various configurations, such as submersible or inline.
