Abstract

A submersible pump (11) comprising an electric motor (1) provided with a power cable (5) connecting the electric motor to a power supply overground. The power cable is internally provided through the entire pump and starts from the motor and extends internally through the motor housing (7) into the strainer (2) of the pump through a liquid tight seal provided in the top end shield (9) of the motor at the periphery thereof. The cable runs through the strainer along the inner wall thereof. The power cable further extends through the impeller housing (3a) of the pump along the length thereof through a sleeve (10) provided in the impeller housing at the periphery thereof and protrudes out through the top of the impeller housing at the periphery thereof liquid tight. The cable further extends to the power supply externally along the discharge chamber (4) of the pump (Fig 1).
