In view of the megatrend topics of energy efficiency, resource minimisation and the reduction of critical materials, it is important, especially in the field of pump technology for air-conditioning and drinking water systems, to break new ground and to promote innovation. This is exactly where the HYDRESS joint project comes in and intends to make innovative circulators possible through the interaction and synergetic use of the different competences of the project partners. We achieve this by new concepts and the use of innovative materials and manufacturing technologies to optimize the main components of the electric motor and pump unit. Innovative materials are used for the circulation pump as well as for its electric drive.
