<p>A centrifugal pump, especially immersion pump, consists of: a scroll case (3) with a rotor impeller wheel enclosed with a suction cover therein; a casing (4) with a constant inner diameter; a stator (5); a partition wall (7); and a cover (8) of the pump. The scroll case (3), stator (5), partition wall (7) and cover (8) of the pump are fitted in the casing (4) with a constant inner diameter. A process for the production of sad pump rests in a stepwise order: moulding said stator (5) into the casing (4); said casing (4) onto the scroll case (3) with a rotor (12); the partition wall (7) into the casing (4); and the cover (8) of the pump into the casing (4).</p> |
