FIELD: oil producing industry. SUBSTANCE: invention relates to centrifugal electric pumps for lifting formation fluid from well. Proposed centrifugal high-lift electric pump has check and drain valves, sludge nipple stopped from top and provided with through radial holes below the plug. Sections of pump with inlet module or gas separator and submersible electric motor with hydraulic protection connected in series are installed on oil well tubing. Ring whose inner diameter is smaller than outer diameter of scraper for cleaning tubing string is installed inside tubing string above drain valve. EFFECT: imp4roved reliability and increased service life of pump owing to prevention of destruction of drain valve. 2 dwg
