Abstract (en)
[origin: EP1520992A2] The circulating pump has a stator (2) located on the pressure side of a rotor. The stator vanes (7) are designed as sheet metal preformed parts, whereby the stator vane blanks are constructed as a development of a conical generated surface and the formed stator vanes are cut-outs of this conical generated surface. A vane side edge located on a smaller radius of the cone (9) forms the free vane inner edge (12) lying next to the rotor's rotational axis.
