<p>The pumping unit described comprises a flow machine (2) having one or more rotors (5) and an electric drive motor (3) therefor. The shaft (6) of the motor (3), on the side facing the flow machine (2), is secured axially and radially by means of a bearing plate (8). For the purpose of simple and rapid sectional dismantling and reassembly of the pumping unit by unskilled personnel without using tools, at least two of the assemblies comprising bearing plate (8), motor casing (12) and housing (4) of the flow machine (2) in question are each provided with a component bayonet formation (18, 19). Furthermore, a single-piece or multi-piece ring body (13), which holds these group components together, is provided with inner (16) and outer (17) component bayonet formations, which interact with the first-mentioned bayonet formations. <IMAGE></p> |
