The article studies common causes of submersible pumps failure. The influence of formation temperature on the operation of submersible pumps is studied. Negative factors appearing, at increase of temperature of electric motor of submersible pump are studied. The influence of high temperature on the material of submersible pump has been studied. The effect and methods of installation of cooling casing for submersible pump are studied. Calculated the flow velocity passing near the electric motor part of the submersible pump. Determined the optimum diameter of the cooling jacket for the submersible pump.
