A circulator pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system. Circulator pumps used in hydronic systems are usually electrically powered centrifugal pumps. Should you have any questions about circulator pumps, you’re welcomed to contact sales@ekaship.com.
