Monoblock pump is a centrifugal pump, the casing of which is combined with an electric motor in one unit. Water enters the pump in the axial direction and exits radially.
The impeller of the monoblock pump is mounted on the electric motor shaft, which allows for a reduction in overall dimensions as well as friction losses in additional bearings. For air cooling of the electric motor, a rotating blade is mounted on the shaft end opposite to the impeller. The blade is covered with a protective mesh.
The universal design and wide range of working parameters allow monoblock pumps to be used for circulation in heating, cooling, and hot water supply systems, booster pump stations for water supply and fire extinguishing, for increasing pressure, and simply for liquid transfer in industry and agriculture.
In heating systems, a monoblock pump is used only if a wet rotor pump cannot provide the required flow rate and pressure, and the noise created does not exceed permissible limits.
