ABSTRACT:
A progressive cavity pump is located in a well and driven by a downhole electrical motor. A connector locates between the drive shaft of the motor and the rotor of the pump. The connector includes a connector shaft which has a lower end restrained on a longitudinal axis. The upper end orbits with the lower end of the rotor. The connector shaft has splined ends that are received in couplings. The connector shaft flexes during the orbiting movement.
