A circulator pump, also referred to as a circulating pump, is a specialised pump designed for circulating gases, liquids, or slurries within a closed circuit. These pumps are commonly used to circulate water in hydronic heating or cooling systems. Since they operate within a closed circuit, their primary challenge is overcoming the friction within the piping system rather than lifting a fluid from a lower potential energy point to a higher one.

In hydronic systems, circulator pumps are typically electrically powered centrifugal pumps. In residential settings, they are often compact, sealed, and have a rating at a fraction of a horsepower. On the other hand, in commercial applications, circulator pumps vary in size, reaching high horsepower, and the electric motor is usually mechanically coupled to the pump body.

If the hazard is considered a low hazard (such as the hazard effects only the taste and odor of the water), the State requires testing once a year.

If the hazard (substance you are protecting against) is considered a high hazard (i.e., a hazard that can cause health problems), the State requires that the device be tested twice a year. If the hazard is considered a low hazard (such as the hazard effects only the taste and odor of the water), the State requires testing once a year.

For instance, sprinkler and irrigation systems are required to be protected by these devices. They are normally installed near the meter in an underground box.

A sprinkler and irrigation system that has a chemical feed requires this device. It is also commonly used in commercial establishments to protect against numerous contaminants. These devices must be installed above ground.
