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.
Hand pumps are another option for people wanting the ability to pump water from a shallow water well manually. Water hand pumps do not require any electricity to function and are powered by the suction force created when someone raises and lowers a lever by hand.
