The article presents the concept of a new circulation pump for low power heating or cooling system, dedicated to systems where it is necessary to ensure a slight liquid flow during periods of operation at a significantly low efficiency of the systems. The assumption for the construction of the new pump was the possibility of its installation in the pipeline axis. The proposed prototype design includes the application of a patented solution to relieve the axial force acting in a flow system [1,2]. Additionally, a new permanent magnet DC motor designed and manufactured for this pump was used. The design of the pump takes into account the requirement of maximum silence, which results from its intended use in close proximity to human habitation. The design of the pump has been tested numerically. The results of numerical tests are presented. The pump was made in the rapid prototyping technique in a 3D printer. The pump was built into a dedicated test stand with measuring instruments verified in terms of the quality of measurements. A series of measurements was made on the basis of which the flow characteristics of the pump were determined. During the research, risks for the operation of the new structure were identified, which will be taken care of in a further stage of the research, and the structure, after removing the defects, will be directed to production .
