In modern domestic heating systems, the installation of a circulation pump allows the circuit to warm up faster and contributes to an even distribution of heat energy. Reducing energy consumption and improving heat transfer ultimately leads to an increase in the efficiency of the equipment as a whole. Typical characteristics of common circulation pumps for heating can be found on the page https://sigma.ua/price/nasosy-tsirkulyatsionnye/ Or similar sites.
Selection of the circulation pump for heating depending on the operating conditions
In addition to the main characteristics of pumping equipment, which include performance and head, it is necessary to pay attention to the design features of a particular model, depending on the type of rotor used in the installation.
Dry rotor circulation pump
This type of pumping equipment is used when it is necessary to pump large volumes of process fluids (heat carrier). This design has a separate arrangement of the electric motor and the pumping part. The connection is made through a two-ring mechanical seal. The efficiency of a dry rotor pump reaches 80%. The disadvantage is the increased noise level.
Glandless circulation pumps for heating
This type of equipment is most commonly used in private households. Despite the relatively low efficiency (up to 50%), such pumps are quiet. A feature of the design with a wet rotor is that the pumped liquid acts as both a lubricant and a cooling material.
There is a separate modification of circulation pumps for heating, in which it is possible to adjust the rate of circulation of the coolant. It is impractical to use such equipment for domestic heating due to its high cost.
Also, when selecting a circulation pump, you must pay attention to its overall and linear dimensions. This is especially true when carrying out repair work or modernization of the heating system, when the laying of the main pipelines is completed. Manufacturers produce a wide range of pumping equipment with identical dimensional characteristics, which makes it possible, when replacing equipment that has failed, to simply replace it with a pump of a suitable design.
