FIELD: engines and pumps.
SUBSTANCE: proposed pump unit comprises electric drive stator with inlet guide vane and straightener blade. Rotor shaft with impeller runs in bearings at the cover. Cylindrical grooves are made at rotor ends. Recesses and cover cylindrical surfaces make the hydraulically communicated groove seals.
EFFECT: decreased unbalanced axial force at the rotor, axial load at bearing and higher efficiency of the pump.
