Pumps with the "Wet" Rotor for the Circulation of Hot Water

To resolve this issue between the boiler and the draw-off points is laid an additional pipeline, and the circulation pump is installed on it. The circulation of water in the hot water system (hot water) is needed for the hot water to be available at any time of the day right after the opening tap. Considering that water needs for domestic hot water is usually unprepared cold water containing hardness salts and dissolved gases, it is evident that standard pumps used to circulate the heating systems cannot provide a reliable and continuous operation. Therefore, for this purpose uses a special pump construction with a "wet" rotor. The features of this series are brass or bronze body (depending on the type), and the impeller is made of stainless steel or special food grade plastic. The main difference lies in the design of the motor, which ensures the absence of it in salt deposits.

Another problem is the formation of dead zones in the heating systems where the water cools even when the pump is running. Among the causative agents of various diseases that may be present in the water, for a man especially dangerous so-called Legionella can cause legionellosis acute infectious disease characterized by severe pneumonia. The most favorable breeding ground for this type of bacteria is warm stagnant water with a temperature of 25 to 50 ° C. In modern boilers provides the function of a thermal disinfection of the water when during the night the water is heated to a temperature of 70 ° C, which is enough to kill bacteria in the boiler tubes and the next. However, water pipelines in remote areas and does not pass the stagnant thermally disinfected, and its use after passing through the pipeline remains unsafe.

To solve this problem helps to pump, the circulation pump with hot water motor supports automatic mode boiler thermal disinfection. With built in determining the start time of thermal disinfection procedures, it provides extra protection against Legionella. Since this procedure is carried out at night, when the circulation pump is switched off, it is necessary that the temperature rise and the inclusion of the pump monitored even when you turn off the automatic timer. Thus, the use of the pump this model allows the first stage to automatically determine the time during which the disinfection of the boiler, while the second - turn on the pump at the right time, ensuring the circulation of very hot water over the DHW system and disinfect pipelines simultaneously with disinfection boiler.
