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.
Centrifugal Pumps. Aboard ship, centrifugal pumps of various sizes are driven by electric motors to move different types of liquid. The fire pump and seawater service pump are two examples of this type of pump. A basic centrifugal pump has an impeller keyed to a drive shaft, which is rotated by an electric motor. The drive shaft is fitted inside a casing, which has a suction inlet and a discharge outlet.
