Circulator pumps have numerous applications, but are particularly useful in heating/cooling systems and for hot water return. There are two types of circulating systems - open and closed. Closed systems are typically used for heating/cooling applications, such as underfloor heating or baseboard heating.
This class of pump is often called a hose pump. The biggest advantage with the hose pumps over the roller pumps is the high operating pressure of up to 16 bar. With rollers max pressure can arrive up to 12 Bar without any problem.
