Circulatory Pumps
A circulator or Circulatory Pumps are pumps that circulate gases, hot and cold water and indeed other liquids, usually in a circuit that is closed.
Unlike other kinds of pumps, circulator pumps only need to circulate their liquids around a closed circuit and do not need to boost or add pressure in the way a booster pump would, for example.
Circulatory pumps are frequently used in heating and air conditioning units as well as in cooling systems.
