FIELD: units for lifting liquids from wells.
SUBSTANCE: proposed pumping unit includes housing with central tube forming three working stages interconnected hydraulically by means of spring-loaded check valves. Sections of central tube located in zones of working stages are tubular diaphragms made from thin-walled alloyed steel. Mounted on boundaries of working stages in central tube are suction valves. Pumping unit is lowered into well by means of lifting pipes and is connected with hydraulic pulsar. Pumping unit is also provided with throttle valve, shut-off unit and storage reservoir.
EFFECT: facilitated procedure of mounting and dismantling of equipment in well; reduced usage of metal.
