FIELD: pump manufacture, possibly lifting stratum liquids and gas-liquid mixture from wells.
SUBSTANCE: pump includes axial stages having stator apparatus and impeller in the form of sleeve with diameter at side of inlet of impeller determined according to outer diameter of impeller, pump efficiency, number of revolution and diameter coefficient of impeller. On end surfaces of sleeve washers of wear resistant material are arranged. On lateral surface along helical line vanes are mounted with predetermined pitch. Vanes have rounded shape of inlet edges with predetermined inclination angles relative to ends of sleeve. Stator apparatus includes sleeve with shoulders on end surfaces and with vanes on lateral surface. Said vanes are mounted at predetermined spacing.
EFFECT: enhanced technological effectiveness, lowered labor consumption for making pump, improved operational reliability, increased useful life period of pump.
