The present invention refers to a coupling device between the rotor parts and the motor of single and/or double- impeller centrifugal pumps. The device comprises an elbow pipe, coaxially incorporated with an impeller and associated at one end, by a joint, with a projection from the shaft of a standardised electric motor. Said elbow can be provided at the other end with means of coupling for another impeller. <IMAGE> |
