ABSTRACT:
A centrifugal pump comprises impeller blades which are pivoted at their inner ends to a rotor so that the impeller blades can rotate relatively thereto between two extreme positionss. The extreme positions are defined by stop means in the form of pins. The construction enables the centrifugal pump to be operated efficiently when driven in either direction, the blades being allowed to flex during operation.
