Radiators Linear pumps PD383 Pumptehran

Usually, according to the recommended standards of facility engineering, in buildings that have 8 units or more, it is necessary to consider the "reserve" circulator pump with the same power, head and flow of the main pump.
If you have a separate water heater, a separate circulator pump for the boiler circulation circuit, for standing coil sources up to 1500 liters, a 2HV inch circulating circulating pump and for standing coil sources from 1500 to 3000 liters, a circulator circulating pump 2AA inch is suitable.
It should be noted that if the lowest part of the double-walled source of horizontal hot water heater or horizontal coiled source in terms of horizontal level is higher than the outlet water of the boiler house collector, then the boiler house water according to the heavy flow and without the need to install a circulator pump between the boiler and the source To heat the water will be consumed in the source.

installation location :

Circulator pumps are usually installed in the return circuit of cooling or heating systems, in other words, in heating systems before the central heating boiler and in cooling systems before the chiller, so that the water outlet of circulating pumps in the systems The heating enters the boiler and then distributes it to radiators and fan coils.

Adjusting the temperature of the wall thermostat installed on the suction pipeline of the circulator pump, it should usually be about 5 degrees Celsius lower than the set temperature of the submersible thermostat of the building's engine room.
