QJ well submersible pump is a water lifting tool, with the motor and pump integrated into a whole body and submerged into water. It is used to draw ground water from a deep well, or from river, reservoir and aqueduct etc., mainly for agricultural irrigation, water for human being and livestock in plateau areas, water discharge in cities, factories, railways, mines and construction sites.

        1、 Integrated body of motor and pump, submerged operation of great safety.
        2、 No special requirements on borepipe and ascending pipe(i.e., it can be used in steel pope well, ash pipe well and shallow well; if pressure permits, steel, rubber and plastic pipes can all be used as ascending pipe).
        3、 small occupation apace, and no need of a pump room.
        4、 Compact and simple structure and small volume.

        1、 Three-phase AC power supply of rated frequency at 50Hz and rated voltage at 380±5％.
        2、 Pump inlet shall be kept below the dynamic level by 1 meter, but the submerged depth shall not exceed 70 meter below the static level. And the lower part of motor shall be kept at least 1 meter to the bottom of the well.
        3、 Generally, water temperature shall not be higher than 40℃.
        4、 Water quality:(1)Sand content in water not greater than 0.01％(Weight ratio);
        (2)PH value between 6.5～8.5;
        (3) Chlorine ion content not greater than 400mg/l.
        5、Well shall be straight and slippery with no misalignment of borepipes.
