What are Circulator Pumps?

Circulator Pump

Circulator pumps are used in closed circuit environments and to pump water though. It also can pump slurries and gases. These pumps are used in homes and large buildings for hydroid heating and cooling which the water is used to raise or lower temperature to a satisfactory level. However, it depends on the size of the circulator pump and the motor needed to push the water, water is either external or internal. Usually, it is the external motors that are much more powerful than the internal motors. If it is used for hydroids, the pump is made from cast iron while the pumps used in drinking water systems are made from bronze.


These circulator pumps are made to push liquid, gas or slurry through a closed circuit that is constantly rotating. Pumps are found paired with water systems for temperature adjustment or drinking with large equipment. In addition, water is the most common material to be paired with a circulator pump with slurries being the second.


Large equipment and machines pieces are constantly running and build up a high amount of heat therefore if the heat is not reduced quickly and constantly, the equipment can melt or cause damage to the surface. By circulating either a slurry or water over the heated parts, this can transfer the heat away from the equipment and into the slurry or water. A circulator pump will continually circulate the same liquid and a relatively small amount of slurry or water is needed for this application.


Often these circulator pumps are used in hydroids and the water in the system is either cooled or heated and passed around the house to raise the temperature. The earliest form of hydroid is the radiator system and to push the water around the circuit however the circulating pump needs to have a motor.


Some small household pumps have internal motors while larger spaces need an external motor. The internal motor is weak but can keep the pump watertight because the pump does not need to interact with anything outside itself. As for the external motors, they need large applications otherwise the water cannot circulate through the circuit but these systems are more difficult to maintain.


A circulator pump will be made of either bronze or cast iron and when used in hydroid, any application in which the water only can regulates temperature. Bronze pumps are used for water consumption and these pumps are used to keep a constant circuit of cooled and heated water so that users do not have to run the water at a sink for several seconds to change the water’s temperature.


The main parts of a circulating pump are the housing, motor, impeller and support bearings. The pump housing consists of a cavity that contains the moving parts of the pump while maintaining a liquid tight seal. The motor is used to rotate the impeller inside the pump housing and is supported by the bearings that have a series of blades that force the fluid in the desired direction. The pump can also be used when a liquid and powder are combined in a solution.


Most circulating pumps are electrically powered and may also be powered using hydraulic fluid or air pressure. The materials used for manufacturing a circulating pump will vary based on the type of operating conditions and solutions. For piping systems that use water, cast iron or aluminum housings with stainless steel or bronze internal components are often used. Applications that use fluids that are highly corrosive or operate at high temperatures or pressures, metal alloys, titanium, and chemically-resistant plastics may be used to maintain acceptable pump performance and life.
