Abstract: A submersible downhole pump (1) includes an elongate pump unit (3) defining a longitudinal pump axis (L) and a pump unit diameter (D), and at least one cable lug (13) for attaching a cable. The at least one cable lug (13) is connected to the pump unit (3) and pivotable around a pivot axis (P) perpendicular to the longitudinal axis (L) between a defined first position and a defined second position. The at least one cable lug (13) is positioned, in the first position, fully within the pump unit diameter (D). In the second position, the at least one cable lug (13) is positioned at least partially protruding outside the pump unit diameter (D).
