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.
Jet pumps create suction in a rather novel way. The pump is powered by an electric motor that drives an impeller, or centrifugal pump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller.
