The tail of the listed equipment is furnished with a tip arranged to translate upward along the crossover show inner surface. The stator is rigidly coupled with the aforesaid tubing arranged to rotate the mouth drive. The aforesaid crossover shoe is rigidly and axially coupled with the hole anchor locked relative the hole walls. The aforesaid tail is arranged beneath the rotor and furnished, above the tip, with the travel limiter representing a stop. Note that the rotor is locked axially and radially relative to the stator. The proposed hole screw pump is designed to be used in minor-diameter holes for production of high-viscosity oil.
