A circulator pump for home use. A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.
Where it is necessary to raise water to a height above that to which a suction or lift pump will operate effectively (about 7 metres), or to raise the pressure so that it will exit a nozzle with a strong force, such as through a fire hose, a force pump may be used. As with a suction pump, in its manual form it relies on an operator to pump a ...

No inherent redundancy for the pump. A zone-valved system is dependent upon a single circulator pump. If it fails, the system becomes completely inoperable. The system can be harder to design, requiring both "SPDT" thermostats or relays and the ability of the system to withstand the fault condition whereby all zone valves are closed simultaneously.
The secondary pump takes the feed water going to the boiler and raises the pressure of the water going in. In a natural circulation boilers, the circulation of water is dependent on the differential pressures caused by the change of density in the water as it is heated. That is to say that as the water is heated and starts turning to steam, the ...
A centrifugal pump which forms the heart of this boiler is responsible to circulate water within the boiler system. It receives water from the drum and delivers this water to a distribution header as shown in the diagram here. The number of headers may differ in numbers and depends on the size and boiler design of each boiler.
A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
