One of the most important elements of modern heating systems with artificial circulation of the coolant is a circulating pump. If the open heating system operates only due to the natural circulation of the fluid, in closed systems for the circulation of the coolant the pump is a mandatory element.
Circulation pumps can be divided into two main types:
Advantages of circulating pumps with "wet" rotor:
The disadvantage of such pumps is their low efficiency of 30-50%.
In autonomous heating systems of private houses and apartments, wet rotor pumps are used.
