The invention discloses a double-stator double-impeller water filling type submersible tubular pump which comprises a stator and a rotor, the stator comprises two annular stator iron cores and a primary guide vane body located between the stator iron cores, and each stator iron core is provided with a coil winding; the rotor comprises a rotating shaft and two impellers, a primary rotor is fixed to the outer edge of each blade in each impeller, the rotating shaft is coaxially and rotatably installed in a primary guide blade body, the two shaft ends of the rotating shaft extend into an inner ring of the stator core to form cantilevers, and the two impellers are coaxially and annularly fixed to the two cantilever parts of the rotating shaft in a one-to-one correspondence mode; and the primary rotor at the edge of each impeller blade is adjacent to the inner ring side of the stator core in the corresponding direction. Friction loss can be reduced, it is ensured that the stator core has enough effective length, an
