FIELD: engines and pumps.
SUBSTANCE: invention relates to pumping equipment for recovery of reservoir fluid from wells. Submersible pump unit consists of pump and valve electric motor equipped with tubular shaft with flow channel, tight thin-wall shell on stator, and at least one hole in wall of housing. Shafts of pump and valve electric motor are connected by means of splined coupling provided with holes in wall. Flow passage in the tubular shaft communicates the well with the pump through the holes in the wall of the splined coupling.
EFFECT: invention is aimed at improvement of submersible pumping unit reliability due to design simplification.
