Abstract
The present invention provides an electric submersible pump assembly with a latch device permitting downhole connecting and disconnecting of the pump and motor. The latch device includes a pump latch connector and a motor latch connector that allows a pump and an electric submersible motor to be disposed in a wellbore independently and then connected. The pump latch connector attaches to the pump and includes a rotor connector box and a stator connector pin. The motor latch connector attaches to the motor and includes a rotor connector pin and a stator connector box. The rotor connector pin is disposable in the rotor connector box and the stator connector pin is disposable in the stator connector box thus connecting the previously suspended motor and motor latch connector to a retrievable pump, with the pump latch connector attached.
