<p>The pump assembly has a pump unit and an electric motor for driving the pump unit, which comprises a stator (2) and a rotor. The stator is separated from the rotor space by a split tube turning in the rotor space. A circular wedge connection (4) between the split tube and the stator, is supported to the stator by the split tube. The split tube has an outer peripheral surface which comprises inner circular wedge profile deviating from the circular shape.</p> |
