FIELD: engines and pumps.
SUBSTANCE: electrical bore-hole pump includes pump section, inlet section, section of protection device and section of electrical motor, which includes power supply and communication unit, and common casing passing above all the pump sections.
EFFECT: creation of compact pump due to combination of functions of casings of the pump section, casing of inlet section and multiple casings of protection device section into one common casing, which reduces the problems with joints, misalignment of bearings and reduces concentricity error.
