The utility model discloses a double-stator water filling type submersible tubular pump, which is characterized in that an axial rotor core is arranged between a guide vane body and a water absorption chamber in a motor cavity, axial stator cores are respectively arranged on two sides of the axial rotor core and in the motor cavity, stator coils are arranged on the outer sides of the axial stator cores and in the motor cavity, and the axial rotor core and the water absorption chamber are arranged in the motor cavity. And a rotor assembly connected with the axial rotor iron core is arranged between the water absorption chamber and the middle position of the guide vane body. The whole structure has the advantages of greatly shortening the axial distance, improving the heat dissipation effect, being compact in structure, light in weight, safe, reliable and the like, the two stator iron cores are innovatively placed on the two sides of the impeller rotor iron core, large friction loss caused by rotation of the im
