What is a circulator pump?
In general, the word circulator means to move, and circulator pumps are pumps that are responsible for moving the hot or cold water of air conditioning systems or central heating of the building from the place of production to the places of heat exchange in refrigeration and heating devices. Are responsible. Circulator pumps are commonly used in small and medium-sized buildings with lower speeds (up to about 1450 rpm).
Circulator pump is offered in two types of steel body circulator pumps and cast iron body circulator pump and is considered as one of the centrifugal pumps.
In other words, after supplying hot water in the central heating boiler of the building and also supplying cold water in the chiller refrigeration cycle and cooling system of the building, the circulating pumps of this hot water or cold water in the pipes (from production to heat exchange points) such as Radiators, fan coils and air conditioning coils are running.
Water circulator pumps for cooling and heating systems, in small and medium buildings, usually have linear and ground types and 1450 rpm and have less electrical power than similar water pumps. Linear pumps on the pipe with gear connection Or flanges and ground pumps are also mounted on a suitable chassis and mounted on bolts with rubber anti-vibration.
Circulator pumps operate very quietly and their motor speed is between 1500 and 3000 rpm. The circulator pump has an optimal energy consumption, and is classified as A and B in the consumption classification.
Circulating pumps are easy to install and have low maintenance costs, and the variety of models and sizes is very high. The circulator pump is also known as circulating water pump, hot water pump, linear pump and circulating pump.
Circulator pumps are very popular among consumers due to their high user base. In this regard, various companies, including Leo and Grandfoss, have produced and designed this product. Abravan Company is one of the leading manufacturers in the field of industrial pumps.
How the circulator pump works
All centrifugal pumps are fitted with a blade called a propeller, which is constantly rotating due to the motor inside the helical chamber. Water enters the pump through the suction port of the pump as well as from the middle of these impellers and our space between the vanes.
If the pump is on, this water in the space between the blades rotates with the help of a finned wheel. After the pump starts to receive kinetic energy by these impellers, it moves to the outer space of the impeller due to the escape force. Finally, water moves outward from the edges of the impeller.
