<p>The pump (1) has a rotor shaft (5) i.e. hollow shaft, carrying an impeller (7) at an axial end. The impeller is arranged in a pump chamber (15). A gap pipe (2) includes a radially outwardly extending flange (8) at an impeller side end. A bearing support (9) with a sliding bearing (10) for bearing the shaft is arranged between the flange and the shaft. An annular prechamber (11) lies between the impeller and the flange, limited into the impeller by a dimensionally-stable separator (12), and communicatingly connected with a rotor chamber (4) by inner and outer channels (13, 14).</p> |
