Abstract (en)
The invention relates to a centrifugal pump for water recirculation. In order to overcome the difficulties in cooling the seal of such a pump it is provided that the pump body, which forms a part with a prefilter (2) is linked to the electric motor housing by a markedly truncated cone-shaped shield (15).
